    They were a one trick pony and were never fighters, but simple short range light bombers.

    Correct, although the F-117 was also a proof-of-concept for stealth that the USAF was able to test in combat while getting some actual work done. If the F-117 had proven to be easy to target, then I suppose that stealth would have remained largely a black-program rumor, if anything, and the ATF and JSF programs might well have resulted in very different aircraft. But since the technology was deemed effective, it became mandatory for all full-fledged fighter projects, so they were forced to go public with it.

    The fact that at the time they were still state of the art,

    State of the art, no–that would have been the still-in-development F-22–but effectively stealthy despite its early design, yes. Although the USAF sensibly wanted to have a limited force of F-117s that they could test in combat in order to justify the ATF and JSF design points to themselves, they couldn’t wait to retire the F-117s as soon as a replacement became available.

    supported by not just the US but NATO with all those force multipliers we keep hearing about, be it jammer, tanker, satellite, UAV, etc etc they were still not safe in an environment where on paper it should have been a walk in the park.

    Well, that’s combat for you–sometimes an Abrams tank gets four T-72 kills in one day, and sometimes a puny RPG to the back of its turret bustle makes all of the ammunition erupt like fireworks, sending the tank back to the manufacturer or the scrap heap in spectacular fashion. It’s still a highly effective design overall, even if one gets wrecked every so often.

    The same applies to the F-117’s stealth–a SAM system has to be rather close to shoot one down and an old system like the S-125 has to be really, really close (almost right under it at typical cruising altitudes), but if that happens, whether by chance or by cunning, then bye-bye F-117. As for the force multipliers, I’m not sure about this case, but F-117s are usually unescorted and operate in areas where there is currently little information available.

    As mentioned the SA-3 is a heavily compromised ancient weapon, yet with the right tactics the well trained AD forces of Serbia put one over on the high tech digital forces of our current NATO overlords. A $2 rifle killed the Death Star.

    That’s always a valid lesson in warfare, but even technology that isn’t perfect can have value, and it would be wise to analyze all aspects of any significant incident to find many truths, not merely point out the obvious and revel in the irony.

    The F-117 was billed as the super stealthy invulnerable bomber.

    It seems that as usual, the news media took a few quotes and ran crazy with them. I recall one reporter mistakenly believing that each F-22 costs $60 billion (in the US, a billion is 10^9), which was really the cost of the entire program, including R&D and production–she kept repeating: “$60 billion for one plane! ONE PLANE!” :rolleyes:

    Its only drawbacks were it had to fly at night and it could only carry two decent sized LGBs and it had relatively short legs. After it was shotdown it lost the title of super stealthy invulnerable bomber and its drawbacks of flying at night, limited payload, and short legs suddenly became an issue…

    Actually, the decision to retire the F-117 came more than six years after the shoot-down, which I would hardly describe as sudden. It was made on December 28, 2005, which was 13 days after the F-22 officially entered service for the USAF. Should we consider this a coincidence that happened to follow six years of protracted suddenness? 😉 No, just like I had said in previous posts, they were waiting to make sure that the F-22 program would survive to reach operational status in sufficient numbers, which then made the F-117 expendable.

    The Su-25T and the Su-25TM are quite different. Hope the A-10C deals with the A-10s friendly fire issues. Isn’t it funny that a plane can be successful yet can be ignored by its own airforce… Both the A-10 and the Su-25 have had upgrade programs but they take so long to be realised in service.

    The obvious reason is that they and their role are not very glamorous. Pathetic, huh? 😡

    They claimed it couldn’t be detected…

    Either I don’t remember that, or I ignored statements simplified for public consumption because I knew the truth of the matter. But regardless, while it’s alright to point out propaganda that turns out to be proven false, which I do nearly every chance I get, it does not mean that everything said by the same side of a debate (with generally much more nuanced arguments) is untrue.

    Youare right, the S-125 has no special qualities. Makes the kill look even more impressive to me..

    It does to me, as well, and I only mentioned it because someone earlier used the shoot-down as a testament to how advanced Russian equipment is.

    And whether it was luck or not, I care exactly as little as I care about luck Heheman might have had when shooting down two IrAF aircraft with his F-15C in one day.

    There was some luck involved because the several missiles that were fired are said to have had difficulty intercepting the F-117. If the whole incident had involved an F-16 from the beginning, then it would have been fired upon immediately instead of making the SAM crew devise clever and well-executed albeit cumbersome tactics, and the missiles would have chased the F-16 around the sky until they either brought the F-16 down or were evaded by it. The F-117 frankly cannot evade SAMs by maneuvering, but it still evaded targeting until the SAM crew managed to get the radar close enough, and it possibly evaded one or two SAMs by stealth alone (tracking would have been intermittent).

    If this is what you believe, how can you call the shootdown a luck? What you have described here is an excellent example of precise ambush tactics..

    I don’t merely call it luck–I give the SAM crew full credit for their excellent work. The luck had to do with one of the old missiles being able to detonate closely enough, and the fact that the USAF’s planners were careless (which was out of the control of the SAM crew, from their point of view). By the way, in an earlier post, I had also attributed the F-117’s previously perfect record in high-threat areas partly to luck. The risk was so great that I’m sure the USAF was surprised that several F-117s weren’t shot down over Baghdad. Was that all due to luck? No, but if I think that a substantial or extraordinary amount of luck was involved, then I will state it because probability is an important aspect of any analysis. To simply ignore it would indicate bias or wishful thinking, whatever “side” someone is on. Disagree with my analysis if you wish, but I’m trying to be as impersonal, dispassionate, and fair as I can.

    1. IIRC, F-22 is less stealthy than F-117.

    While the F-22 was still being developed, this was a common belief, even among its supporters. The reasoning was that there was something “ideal” about the F-117’s method of achieving stealth and that the F-22 must have compromised on this substantially in order to have far superior aerodynamics. This logic turned out to be based on false assumptions.

    What we learned later was that the F-117 was a rather crude example of stealth technology, with the reasons being the lack of computing power available to its designers (used to estimate reflectivity), and that they simply knew less about stealth techniques back then. It’s not the faceting alone that creates stealth but also their positions and relative angles to other facets that physically make electromagnetic waves at radar frequencies bend or diffract around the aircraft to an extremely high degree (resulting in several orders of magnitude of RCS reduction, if not more). Both techniques are useful and effective in their own ways, and must be combined in order to achieve stealth.

    The F-22’s VLO design is a superior combination of these techniques made possible by greater computing power and undoubtedly by a far greater amount of money being spent on it (which translates to research and effort). Where larger “facets” are advantageous, the F-22 has fewer of them in order to reduce the probability of detection (the tradeoff was detection at longer ranges, but this is considered the superior compromise). And where the other technique is required, while the F-117’s facets–necessarily large due to primitive computers–glitter like a disco ball at some distance in many directions as it moves, the F-22’s smooth shapes–essentially an infinite number of carefully aligned facets–result in a consistently VLO radar return while also allowing for superior aerodynamics. In short, the F-22’s stealth is both more advanced and superior to that of the F-117 in the context of actual combat.

    2. You take an aircraft 25 years newer but still keep the same ancient SAM system which was obsolete even in F-117 times.. God, you really know how to design a story to you favor 😉

    🙂 I was merely giving everyone an example of one of the major differences between the F-22 and F-117, namely sensors (the ALR-94 alone probably costs more than a whole F-117 😉 ). I was simply being scientific in changing as few variables as possible.

    My piece of advice: take S-400 or at least S-300PMU-2 and reconsider.

    Point taken, but it would change nothing–in an otherwise identical scenario, the F-22 would likewise detect the S-400 searching for it, and either report its location and evade it, or attack the S-400 site itself if hunting SAMs is of a higher priority than its primary target.

    Unfortunately, that is exactly what F-22 cannot do..

    While the F-22 is currently limited in the weapons it is cleared to carry and does not carry IR targeting equipment, it is the most accurate JDAM platform (probably due to its avionics), and the upcoming GBU-40 (SDB II) will give it a potent weapon against even mobile targets. That should be good enough until the F-35 can take over for the F-117 completely (and then some).

    By claiming it was invisible to radar they were claiming it was invulnerable. You can’t kill what you can’t detect.

    Even if they were making such claims, you’re not arguing with them on this forum.

    Just because it was faceted doesn’t mean it wasn’t stealthy… and equally just because the B-2 and F-22 have curves it doesn’t necessarily mean they are more stealthy.

    You’re probably right in a “mathematical” sense, but in combat the F-22 is indeed more stealthy. It has far fewer glints, which significantly reduces its probability of detection at intermediate ranges (i.e. between obvious BVR and obvious WVR). This advantage becomes more pronounced as range decreases, making the F-22 even harder to actually kill once it has been detected. In addition, because the F-22 can detect, categorize, and plot threats, its pilots can maneuver to remain hidden from detection, whereas F-117 pilots are pretty much flying blind in comparison, depending far more on luck for survival. And aside from defensive considerations, while enemy fighters and SAM sites might be hunting the F-22, the F-22 is hunting them, too, and it’s going to see them first in virtually every engagement.

    There is no reason to believe that technology and tactics worked out to defeat the F-117 wont work on any other stealth design.

    The same tactics would not have worked against the F-22. If you attempt to gradually zero in on that thing from a distance with radar, it will locate and kill you (or get someone else to).

    BTW with the Skat the Mig Design Bureau is developing a UAV with similar attributes to the F-117 except that it is unmanned. Of course a 2,000km flight radius sounds better than the F-117s radius without inflight refuelling.

    Well, it looks like they think that stealth is a useful feature.

    The F-117 was supossedly to be invulnerable but it is not and the thing that shows it was more of a publicity rather than a real military threat is the fact that a 1960`s SAM that was used in 1973 to kill F-4s, killed a 1980`s supposedly more modern Stealth fighter, it was not even the modern S-400 but a very early SAM that was supported by an air force of only 14 MiG-29s and a small nation of a few million people in the middle of a civil war, it was not a military superpower like Russia or China or a powerful regional power like India

    There is no point in us arguing over this because I have never considered the F-117 invulnerable, myself. The USAF, for their part, never explicitly claimed invulnerability, and they never hid the fact that it only flew at night (that’s funny, they even flew the 1960s F-4s during the day). If you’re suggesting that many people (not anyone I’ve seen in my short time here) believed that it was invulnerable anyway, then obviously a shoot-down–under any circumstances whatsoever–proved them wrong. Well, there’s no arguing with that logic, either, but when stated repeatedly to those who have always known better, it seriously begins to look like a “strawman” argument. The potential implication that stealth technology failed to achieve its alleged (falsely so) goal of invulnerability and is therefore a failure in general is equally misleading. And for all the talk about the S-125 being a 1960s system, as I’ve already pointed out the F-117 is just as crude an example of its own technology as the S-125 (probably even more so).

    Now, if you’ve been trying to say, indirectly for some reason, that the F-117 was retired because it was no longer useful as a USAF propaganda tool for self-deluding people, then I’d accept that as a possible factor that made the decision for retirement easier, although the other reasons I’ve given still stand.

    Why to retire the F-117 if it was really stealthy?

    Despite being a primitive early example of the technology (isn’t it obvious?), the F-117 still is really stealthy–we just seem to have different conceptions of what this means. To me it means that radar detection and tracking ranges are reduced to a small fraction of what they would normally be for an aircraft.

    I’ve already explained why the F-117 was retired. In a nutshell, it is a crude aircraft that provided a single unique capability that is no longer unique now in the USAF inventory. Additionally, the airframes are old for an aircraft of its size and class, there is no reason to build more of them with the F-22 and eventually the F-35 to take its place, and its stealth is more costly and time-consuming to maintain. The last part is significant, as the USAF retired their fleet of EF-111A Ravens so that they didn’t have to keep a small number of a unique type flying, despite still having a major requirement for their capabilities; this was fulfilled by sharing EA-6B Prowlers with the US Navy, but it nonetheless shows their strong desire to reduce the number of individual aircraft types in their inventory whenever possible. For the record, the USAF actually considers both the F-15 and F-16 obsolete because of their lack of stealth, but they are numerous and ultimately every air force needs numbers. If it were up to the USAF, they would eventually replace every F-15 with F-22s and every F-16 with F-35s.

    well simple modern SAM can even hit F-22s according to Russian statements,

    And if for some crazy reason an F-22 flew at medium altitude right over an S-125 site, then it could potentially be shot down, too–you wouldn’t need an S-400 to do that. Likewise, you could kill somebody just as dead with a Springfield M1903 from the year 1903, shooting right through a modern “bulletproof” vest using the latest Spectra materials.

    As for “Russian statements,” well, Russian government officials have also claimed that the Su-30 and Su-35 are stealthier than the F-22, which is ludicrous. Any SAM system could shoot down the F-22 depending on the circumstances, so while the oversimplified statement here is literally true, it is devoid of any real information. It tries to imply that modern SAMs (Russian, I presume) can detect and shoot down F-22s from the same range and with the same effectiveness as they do other fighters. The only appropriate response is that extraordinary claims require extraordinary proof.

    and once you have a good radar to deal with F-22s that still radiate and bounce energy back to its source well, then fighters like the Eurofighter or Su-35BM can become handy,

    F-22s do in fact bounce energy back to its source, but nothing like these other fighters do–not even close. In the vast majority of cases, they will be tracked, targeted, and shot down first by F-22s. If you can think of tactics that could be used to effectively counter the F-22, I’d like to read them.

    IIRC the F-117 initially was called “The hopeless diamond”. I also once heard, “It has the RCS of brick, but flies like one too…:D”. So I guess the thing has done pretty darn well for a flying brick….

    The F-117 was a highly successful design, especially when we consider that it was sort of a stopgap until more refined designs could be produced. Nobody was sure whether future programs could or would produce VLO fighters, and the USAF wanted a few dozen examples of a workable, if rudimentary, stealth aircraft. It was never seen as a type that would be flying forever as the ultimate example of stealth–it was just the first of its kind.

    For ground attack I take A-10C if you ask me. Sturdy, durable, armored, with heavy punch, good ejection seat and engines that eat up anything including used frying oil. It would require three hits to take me down. Plus the new N/AW capability which brings the ‘bolt into the 21st century, and the GAU/8A is still the best antitank gun mounted on an aircraft

    I like the Avenger cannon as well as the positions of the engines, which seems to make them less vulnerable to MANPADS (being turbofans could also help in terms of IR signature), although the Su-25TM/Su-39 is also a very good CAS airplane.

    The reality is all aircraft have flaws and the F-117 was retired simply becasue the new generation of SAM are deadlier than even the SA-3 that shot one proving that still is not invulnerable.

    Well, first of all, I’m sure that the USAF has always known about the F-117’s limitations, whatever the public perception/marketing was. If the F-22 program had been properly handled (i.e. been given consistent funding, had more focus on finishing testing and development than marketing to keep the program alive, etc.) and had been completed earlier, then the USAF would undoubtedly have begun retiring the F-117 earlier. Pretty much all it was uniquely useful for, as a stealth “fighter,” was making a mad, mostly blind dash through heavy air defenses (early in a war) hoping that it didn’t happen to get too close to a SAM battery or that SAM radars could not track it well enough. For any other aircraft, this would have been suicide, but the F-117 was both survivable and lucky enough to escape virtually unscathed, at least until somebody outsmarted the USAF that one time.

    That said, you are correct in that the new generation of SAMs (which the USAF has not yet faced in combat) would increase the risks associated with such tactics to the point where the F-117, unable to determine the safest route through expanded radar coverage, would now more likely be shot down than survive. Without the F-22, it might have been kept around for certain kinds of missions against less sophisticated foes, but with the F-22 in service, its time had definitely run out.

    The point I was trying to make was that the S-125/SA-3 shoot-down was not in itself what forced the F-117’s retirement–it would have happened around the same timeframe anyway. If there was any effect, it would have been through public perception rather than any revelation on the part of the USAF. I basically agree with your other points.

    Actually the Germans got the idea by observing the RAF Mosquitoes which would barely show in the radar, or would only do so at decreased ranges. Plus with the speed of the Mosquitoes, these light bombers were difficult to intercept. Even at that time, it was understood that wood does not reflect radar very well.

    I’m sure that it wasn’t long until RAM was developed, either, probably to use on parts of radar systems themselves at first. Almost nothing we talk about today regarding stealth wasn’t thought of decades before the F-117–it’s the application of scientific knowledge and ideas that takes a while to catch up. It should be noted, however, that even a primarily wooden aircraft would not be considered very “stealthy” in the modern sense, due to uncontrolled reflections from metal parts, both external and internal.

    Wood as you know, is a natural composite.

    I know what you’re saying, but pedantically speaking ;), “composite” simply means a material that combines two or more base materials in a manner that combines their differing properties while keeping the base materials distinct. There are composites that contain metal and therefore probably reflect radar very well. However, wood is a natural organic polymer, and the plywood that they undoubtedly used is considered a type of composite. Sorry, I’m just trying to be accurate. 😮

    So the Germans wanted their own Mosquito. It was a twin engined zerstorer/night fighter/schnell bomber that went by the name Ta-144, as it was Focke Wulf’s Kurt Tank who worked on that. However, the plane had problems staying glued together.

    Interesting…I’ll have to look that up sometime.

    The Horten wing would have been a horrible plane to fly. The Northrop YB-49 also demonstrated that these things are just horrible to fly, leading to their cancellation. FBW was the major breakthrough that enabled flying wings to be flight manageable.

    I wonder (and hope) that the thought that these aircraft may be somewhat unstable would have at least crossed their minds. Perhaps they believed that human pilots could react quickly enough to fly them safely…I guess they couldn’t. 🙂

    The question is if the F-117 was invulnerable, then why there are reports of some F-117 damaged and the early retirement of an aircraft that is basicly unvulnerable?

    Who said that the F-117 was invulnerable? It is inherently very difficult to detect and track at useful ranges, which is why it had value under certain circumstances, but it is definitely not invulnerable–nothing is.

    Look in the US air force the B-1B and B-52 are still flying and they flew before the more “powerful and invulnerable F-117 specially when the B-52 is too old”

    The B-1B and B-52 are still valuable because of their range and payload capabilities, but they would never be used in the same manner as the F-117 because most likely every single one of them would be shot down during their first mission–it is simply not a fair comparison. Also, being larger, more expensive aircraft, they were designed with much longer service lives, and were flown more like airliners than fighters.

    Of course the excuses will abound but the reality weapons are not invulnerable sooner or later are destroyed in combat and always there are going to be reports of more aircraft shot down.

    No excuses are needed–the F-117 or any stealth aircraft can be shot down if they get too close to a SAM site or another fighter (due to tactics and/or luck). However, this does not change the fact that they are significantly less vulnerable to being detected and tracked by radar systems than conventional aircraft. The F-117 is too simple and crude to take full advantage of this capability–it’s not much more than a concept demonstrator equipped with FLIR and a laser designator, and it’s definitely not a fighter–but there are more complete, advanced stealth fighters already flying and being developed.

    Russian airraft are like any other airraft designed in the west, they have flaws and virtues and as such some are good and some are not so good or even bad weapons

    This is true enough.

    but in general russian aircraft have flaws and virtues and in Combat do kill enemy aircraft and have some degree of effectiveness and also some are destroyed in Combat and the proof is they are still sold

    As far as I’m concerned, the proven effectiveness of Russian SAMs means that their industry knows what its doing regarding weapon systems, and if their aircraft can fly well, which everyone can see for themselves, then they should be quite capable in combat. While they may not be as proven by some measures because of circumstance, I wouldn’t dare to underestimate them.

    The way I see it, a desperately outdated SAM system with constant maintenance and spares shortages managed to take down a dedicated stealth attacker.

    While this is true, just to make things clear for everybody, even the crudest radar can track a VLO aircraft if it is close enough, and the F-117 itself is a very basic machine that relies almost entirely on its stealth for survival (that’s why they only cost $45 million each despite the new technology and limited production run). It does not have a jammer (the S-125 is more vulnerable to ECM than modern SAM systems), nor does it even have chaff and flare dispensers (as far as I’m aware). It was always intended as a special-purpose tactical bomber produced under a limited program while more advanced designs were being worked on. And although it may be “dedicated” to stealth, that’s only because stealth is its only defense–between the two, the F-22 actually has superior stealth characteristics against radar, for example.

    For me this is a huge achievement.

    It is a very impressive tactical feat achieved by the SAM crew, but it’s not because of any special qualities of the S-125. It probably took a fair amount of luck, too, although most everything people do requires at least some.

    Keep in mind, that at the time the S-125 was designed, the word ‘stealth’ was not even in Cassell’s.

    Neither the terminology nor the technology matters if you can get close enough. In this case, unless my sources are inaccurate, it appears that the S-125 crew had managed to momentarily detect F-117s at some unknown distance using low-frequency search radar, which is not surprising (it’s just physics). They discovered a regular pattern or repetition in the flight paths of the F-117s over a period of time, and moved their S-125s close to where they believed the aircraft would fly next; the crew also placed spotters along the flight path to visually (or aurally) detect the aircraft and warn the SAM operators ahead of time. Then when one F-117 predictably flew too close to the S-125, the targeting radar finally managed to lock or track it well enough to shoot it down with a missile.

    From the point of view of the F-117 pilot, there wasn’t much he could have done, really. The air campaign planners should have varied the routes more, but it’s possible that they were either overconfident in the F-117’s stealth capability or they had no idea that SAMs were operating in that area. In general, it’s always possible for an F-117 to fly too close to a SAM site just by pure chance, but in this case, it was the enemy doing an excellent job of concealing themselves (SAM stealth!) and exploiting any weaknesses they could.

    So does this shoot-down mean that the F-117’s stealth was worthless? Absolutely not–it was still a very difficult plane to shoot down in general, despite having no other defenses. But the poor mission planning on the part of the USAF, good luck, and smarts all worked in the favor of the SAM crew that day. The natural question to ask is: what does this incident imply for current VLO fighters? Humans can be clever creatures at times, so as far as developing and using new tactics goes, that remains to be seen, but this case shows that it still wasn’t easy to target a VLO aircraft, and that’s how it will likely remain for some time.

    However, I can say that if an F-22, for example, was involved in this incident, things probably would have been different. Early on, the F-22’s ALR-94 would have quickly located the search radar, whereupon a Wild Weasel team could have been dispatched to seek out and destroy the SAM site. Even if we hypothetically skip this part and assume that the F-22 somehow unwittingly got too close to the S-125 (which is also less likely due to its superior stealth), then it probably would have survived anyway because of its cruising altitude of 50000 feet (normal for the F-22, which “likes” altitude), its countermeasures, as well as its agility (the most agile, mobile American fighter as opposed to the hobbled F-117). A more modern, sophisticated SAM may be able to hit the F-22 under such conditions, but probably not the S-125.

    It should be clear now why the F-117 was slated to be retired soon after it became apparent that the F-22 would achieve operational capability. Although its stealth, per se, was still effective and it was an excellent precision bomber, the F-117 couldn’t do anything else. It was defenseless against other fighters and SAMs that happened to be fortunate enough (or had crews clever enough) to detect it, it had no sensors other than FLIR to give better situational awareness in order to maximize its capabilities, its growth potential was limited, and it was too old to be worth upgrading much anyway.

    As for the main subject of this thread, man what a can of worms! 😮 I’d have to agree with most of flex297’s answers, actually, because far too much depends on circumstances and timing for anybody to make sweeping generalizations about the relative merits of aircraft produced and used by different countries. While there’s no denying that aircraft of Western design are more proven in combat, this too is at least in part a matter of circumstance. It means that the designs are good enough to succeed when used properly, but does not necessarily mean that Russian designs are not good; the exact same principle applies to SAM systems if we switch the two sides, also a result of circumstances.

    Of the SA-3 and the F-117 one is soon to be withdrawn from service… and it isn’t a SAM.

    Well, if both the F-22 and F-35 programs had been cancelled, then the USAF would likely have decided to keep the F-117s going indefinitely. Everyone should know by now (or from the beginning, really) that F-117s are incomplete fighters and have special vulnerabilities, which is why they generally only fly into combat at night. That said, they would still be the only attack aircraft that the USAF would risk sending into a dense SAM environment early during a war, even if it’s possible, however unlikely, that they would be shot down. The F-117 was not sent into retirement by a single shoot-down, it was superseded by a more capable aircraft.

    Stealth application in aviation is actually an old concept. I read somewhere that the Germans tried to build a wooden fighter in World War 2 to reduce RCS.

    That’s right: the Horten flying wing, which happened to have a favorable shape in addition to the materials, although I’m not sure whether the Germans were going for stealth or trying to compensate for shortages in metals while increasing range. It seems that almost every idea that finally gets applied has been around for a while, which represents a natural technological lag. The main questions that should be asked regarding each application should be: 1) how effective is it in its current environment, and 2) what tradeoffs does it force? I think you’ll find that each case is unique in how it answers these questions, especially when you examine all of the details involved.

    By the way, if this is too generalized in a “typical western” manner for 1MAN, then (deep sigh) I suppose I could go over a few examples. 😉

    Answer to Dork Matter
    You are almost completely right in the most in your excellent description of two formidabel aircrafts and I am very impressed you say that in reality the F-22 and F-35 have a radar operating for you. If so – why don’t procure unmanned planes?

    Answering your question in earnest (although I assume it is rhetorical), I strongly believe that a human still needs to be in the loop, and that he (or she) needs to be in the cockpit rather than relying on datalinks that could be compromised.

    Despite your fine answers I think you and many enthusiasts for that plane have forgot new workload in modern aircraft

    While aircraft crews do have some new things to worry about, it is offset by not having to worry about the engine flaming out by advancing the throttle too quickly, or navigating by dead reckoning–these tasks are handled by computers now, and at these kinds of tasks, they’ve generally become better than humans. Yet back in the days of WWII, fighters typically had a crew of one, as they’ve almost always had since then, and he had to worry about all those things. Some of the most successful dive-bombers back then had a crew of two, but the second guy was primarily a rear gunner that tried to keep attacking fighters at bay in order to buy some time. Some fighter-sized bombers had a crew of three that included a separate navigator/munitions officer, but that did not make them any more successful.

    but mostly the cost and that it already is too old, expensive, irrelevant and counterproductive for the 21th combat environment.

    I don’t see why they are irrelevant and counterproductive. While aircraft like the F-22 and F-35 have not been needed for the most recent conflicts, the USAF must be prepared for any potential conflict against far more powerful adversaries that have more sophisticated and more numerous equipment. The goal is to be able to overcome any adversary decisively, not fight a long and bloody air war against even major powers or take heavy losses from ground fire against smaller militaries, which becomes increasingly more likely as improved SAM systems become available.

    I think instead there is a better need to “jump” directly to create the next- sixth generation platform.

    That’s exactly what former US Secretary of Defense Donald Rumsfeld said while he was trying to kill off the F-22. The problem is that it is difficult and risky to look far enough ahead, not only in projecting the threat environment but in predicting how far certain technologies could be advanced to meet those challenges. In my opinion, the USAF has a near-immediate need for better, more survivable fighters.

    Best suited for that is, at least as gap-fillers, use a mix of one/two-seat equipped either F/A-18E/F, F-15E Strike Eagle, Eurofighter, Rafale, Gripen or perhaps even(?) the Su-27 family and MiG-35, longer than expected because the risk for a recenssion or for worst case situations the world can be hit just now.

    As periodic recessions are part of the normal business cycle, I would be somewhat reluctant to preemptively cancel programs on which tens of billions of dollars have been invested, as well as settle for a force of gap-filling fighters, just in case a large number of American consumers finally decide to pay down some of their credit card debt. 😉

    You almost pointed exactly into the political eyes when you described “three or more peoples” in a combat aircraft. That is very funny but I will “ironically” add it to four; each from the air force, army, marines and Navy, that to do all force services satisfied.

    Your photomontage would make a great political cartoon! 😎 By the way, that’s how many crew members are normally on board the EA-6B Prowler, and these days they do fly with mixed crews from the USN and USAF. 🙂

    I can’t ever understand why not generals from different services don’t build bridges and can cooperate more in all useable combat aircraft and work operative in same sensor pipeline? There must be something wrong in modern strategic and tactically planning when every general, in their own services, are working for their own system and grandmothers. Too many people don’t work enough integrated today – 2008. There are for example big fights between services in the military force about whom going to command all UAV/UCAV instead use them together by operators in two-seat aircrafts for all forces (CAS).

    I don’t understand, either, but that’s the nature of bureaucracies, which are mainly under the influence of control freaks. That said, ultimately just about everything is about control–even those who literally fight for their freedom are fighting for control over their own lives and destinies. But I digress.

    They are the best to link the best picture to the pilot and all users on the battlefield. You don’t need to earmark him as an air force operator except in the air safety role. He can be a commander from – example, an army battalion, a SIGINT system, or “why not(?)” the coast guard or the police services.

    That’s exactly what they’re trying to do, but there are major investments involved in making the sharing of all of this information as automatic, reliable, and secure as possible in a “messy” combat environment, which is the only way to overcome the reluctance of some of the leadership.

    The back seat must be suited for the best use in the right environment in the right future!

    I don’t think that anyone would dispute that having a second seat, per se, would be better than just having one, but it’s not free in terms of both training and retaining qualified crews, as well as making compromises to the aircraft. Actually, I’m in agreement with you that it would be prudent to at least have this provision available just in case, but what I’m arguing is that the current situation is not nearly as bad as you think it is.

    There is also more need to communicate over the radio-frequency spectrum because all operation demands that. Only the pilot is not enough, I am sure. Think how much you private are using your handheld telephone and all the need you use in the cyber (internet) world.

    On the other hand, too much of this kind of communication can drive people crazy, as well. 🙂 I don’t think it necessarily makes me more productive, and I always found a way to get things done in the past.

    Anyway, even so, during Red Flag this is how F-22 pilots–in their lonesome little cockpits–coordinated with AWACS to provide the entire “blue” force with accurate identification and targeting information from the F-22’s sensors, resulting in an unprecedented level of success (for the blue force F-15s as well). It would have been easier, however, and more quiet if a Link 16 transmit capability were integrated into the F-22 (it can currently only receive). In any case, a WSO might have helped, especially without Link 16, but the pilots seemed to handle this unanticipated level of radio communication just fine.

    This is a extensive work even in one-seat equipped fighter as F-35A and F-22A. A pilot don´t like internet protocolls during hard g´turning.

    If an F-22 or F-35 pilot finds himself in a dogfight, then it probably means that his primary tactics have failed, at which point he must focus on ACM rather than things like internet protocols. Under such circumstances, while a second pair of eyes in the back could come in handy at times, it’s really up to the pilot to fight for survival; the people with which he must coordinate would be his wingman and other elements of his group.

    I want to make it clear that I’m not trying to belittle the role of WSOs, here. In some aircraft (mostly larger ones) and under certain circumstances (e.g. an F-15E hugging the terrain at night), they are essential personnel. It all depends on the roles assigned to aircraft, the capabilities of the aircraft, and the tactics used.

    I want to stress – pilot workload in too modern fighters are more related to political economical demands to save money than to do a force better in an operation safer with two.

    Yeah, there’s always that, and there’s no avoiding it, either.

    The fight between own force services is dangerous instead choose a common combat plane suitable for all force services.

    Well, sometimes just a single force needs more than one type, so it’s reasonable for them to want different variants of the same basic system.

    If you go to F-35A or F-22A first, it’s going to be a long time to get the sixth generation aircraft faster. Future combat planes perhaps are unmanned and have a capability as doing F-35A superfluous already when they enter their service.

    I’m not willing to look that far ahead regarding required capabilities and technological possibilities.

    That’s why I am most critical and because I am looking at new thinkings when AESA will be equipped in –for example, the new generation of Gripen which is going to be roll-out in April this year but even other equaling combat aircrafts.

    You can put an AESA on any fighter if you wanted to (some F-15Cs have them and more will in the future), but you can’t make them VLO, which more than anything else is the raison d’être of fifth-generation fighters.

    To control unmanned aircraft you have to use them inside the combat area or from a carrier battle group closer to the targets – not only from Creek Air Force Base in U.S but even from your backseater. I should have want to describe that better but primary it is an absolutely need to reduce pilots workload in the future even if most of the tasks are automatic, as you described, in the F-35A and F-22A.

    OK, although this will depend on how sophisticated we can make the UCAVs and the kinds of workarounds we can come up with for any limitations, I see what you mean about the potential of having a second seat. But that’s only one vision, and I suppose it would be possible to add a second seat if that becomes necessary, if not to existing airframes then to new ones; F-35s in particular will be built and acquired over a period of time. It’s probable, however, that the USAF would prefer to use larger aircraft for such a purpose because it lets more people work more closely together when necessary.

    With today’s very advanced air defences, it doesn’t matter if you’re piloting F/A-18E/F or F-35A, because you dare not to fly into a heavy threat environment without electronic warfare protection a.s.o.

    Such protection should be much more effective when used in conjunction with stealth, however. I suspect that even lowly chaff is going to make a big comeback among countermeasures (assuming that the F-22 or F-35 actually get targeted at some point). 🙂

    Shooting down enemy aircraft – has perhaps no meaning in 21st-century warfare. Al Qaeda and the Taliban have no air force, nor do they coming to.

    Except for airlines….

    The threat are today merely the Russian or China but you can´t do anything else than discover them with your AESA and shoot your Meteor – the best man discover the foe more quickly by a skilfully operator and he is a senior operator with the “right eyes”.

    Not all AESAs are equal, and not all “stealthy” targets are, either. Fighting F-22s and F-35s is not going to be like hunting cruise missiles at all, I can tell you that. It’s not going to be a fair fight–Raptors and Lightnings hide in the shadows and play dirty. This is not arrogance or nationalism speaking, it’s simply what these fighters were physically designed to do, and it’s presumably one of the reasons that they cost so much.

    Su-35 has 12 points, the wintips may be occupied with ECM pods. It also can carry four R-77 missiles under the fuselage between the engines.

    There are only two hardpoints (tandem) between the engine nacelles, so are the R-77s carried on double launchers or are you including the two hardpoints under the nacelles themselves (one each)?

    Never mind–somehow I missed the diagram indicating that four R-77s can be carried in the “tunnel” between the engine nacelles. They’re probably carried on double launchers. Imagine having double launchers on every station that could carry them, which is most likely the middle eight–that would make for a loadout of 20 R-77s (18 with ECM pods). 😮 Such a loadout would never actually be used in combat, but it’d make a great photo opportunity. 😎

    Regardless of the intake design, the YF-23A met the USAF’s LO requirement, with some people claiming that it actually exceeded the requirement.

    I could be wrong, but I’ve always thought that the RCS measurements were done on high-fidelity pole models of the EMD designs at the time. The YF-23 and YF-22 demonstrators–which were based on earlier designs–were used to validate the predictions that both contractor teams had made regarding flight performance, particularly supercruise. If this is true, then the YF-23 demonstrators didn’t necessarily have every piece of equipment related to low observability as a result, and the same could have been true of the YF-22 demonstrators. I wasn’t questioning whether the production F-23 would have been stealthy, but what effects the changes that were made from the YF-23 design to the F-23 design might have had on engine performance; obviously, there are a lot of variables to consider. It’s all academic now, of course, but still kind of interesting.

    Previously, I had always “waved my hands” and blindly assumed that the YF-23’s intakes were still stealthy, as if stealth were a form of magic, but obviously it’s not magic, it’s a matter of physics and technology. If an engine face (or even more) is exposed over a fairly wide range of frontal angles, then something has to be done about that, and I wonder what was really going on in this case. I had wondered about the X-32, too, but that mystery has been revealed, and it got me thinking about the YF-23 and the old ATF controversy again.

    You can look inside off a microwave offen (mesh) but no microwave is transmitted outside.

    This is basically how the F-117’s engines are hidden from view, with the intake area behaving as just another facet; while this method is ideal for stealth, it affects engine performance substantially, of course.

    Is the distance between the baffels smaller as the wavelengt than block this the HF to travel inside of the duct. The first compressor stage is than invesible for a RADAR.

    The B-1B’s system evidently affects engine performance at high speeds but not as much at lower speeds and thrust settings, and the same could probably be said for most other inline blockers.

    However, it just occurred to me that with the exception of the F-117’s system, polarization may play some part in the effectiveness of radar blockers. The B-1B’s blockers are arranged in a single linear orientation, while more recent blockers mounted on aircraft such as the Super Hornet (mounted inside the intake near the engine–see the bottom-left attached image) and X-32 (mounted on the engine itself–see the bottom-right attached image) have a radial arrangement, but putting aside the specific configurations for the moment, they would all seem to allow some measurable amount of radiation to pass through, depending on the degree to which they behave as polarizers.

    Because the vanes have to be somewhat narrow at the wavefront in order to allow sufficient airflow, the blockers probably do behave as polarizers, albeit poor ones that fortunately reflect more than half of the energy coming in (ideal polarizers would be thinner and transmit half of the energy). There is also a large portion of the area in question that can be blocked (and reflected onto RAM inside the intake duct) by rotating the vanes, which trades off between RCS and airflow. This tradeoff is fixed in the Super Hornet, and appears to be quite aggressive, actually. In contrast, the X-32’s vanes were movable, closing down as much as they could during cruise in order to minimize RCS, and opening up when higher thrust was required, which increased RCS. I don’t know how fully they could have blocked the engine’s face during cruise, but in theory you could get complete blockage with very wide-chord vanes at the cost of engine efficiency. Comments from those who have real knowledge about things like polarization are welcome. 🙂

    This critical look at intake radar blockers brings us back to the question of the YF-23–with the engines removed from an otherwise intact airframe, you could see clear out the back of the airplane through the intake from some frontal angles, to which I first made reference in the following post:

    http://forum.keypublishing.co.uk/showpost.php?p=1212122&postcount=305

    Granted, the YF-23 was merely a demonstrator, but if the production F-23 was going to use internal radar blockers or a different intake design in order to hide the faces of its engines from radar, this would rightfully call into question its high-speed and supercruise capabilities vis-à-vis those that the YF-23 demonstrated, in my opinion. I don’t know whether this drawing I have of the F-23 (see the top-left attached image) is accurate, but it does show a different intake design.

    Relating this side-discussion back to the main subject of the thread, although I don’t have the data to do the necessary calculations to get the real (at least theoretical) answers, I don’t think I like the idea of using radar blockers in VLO aircraft because I’ll always wonder whether flying fast or accelerating hard would significantly increase its vulnerability to powerful, sophisticated radars like the Irbis. However, this is a moot point because the F-22 and F-35 (not sure about the B-2) don’t need or use intake radar blockers, as far as I’m aware. The complete line-of-sight blockage in the F-35 is so obvious that no example is required, and the attached image (top-right) of an F-22’s intake and S-duct is rather conclusive, as well–if you visualize the location of the engine way in the back, there is no way that it would even be close to visible at any angle unless you crawled halfway up the duct. 🙂

    There are only speculations what 1.42 looks like. Insiders say it is still classified, and imply it have had weaponry bay. The project is surely cancelled

    It’s interesting to realize how early the USSR was trying to incorporate stealth technology (apparently), at least in comparison to what most of us had thought. Being forced to wait until after the F-22 became operational (which was never a sure thing) and the F-35 went into full-scale development will at least give Sukhoi a better sense of what could and needs to be accomplished (and perhaps what doesn’t).

    and also engine AL-41 (but of course when we have to deal with classified things we can’t know the exact situation).

    I can’t say that I’m surprised, not only because it has been troubled for so long, but it may actually have less growth potential than the venerable AL-31F. The main problem appears to be that the design intrinsically depended upon materials technology that may have turned out to be a practical dead end (just a guess). It’s probably better to start over at this point using the lessons they’ve learned.

    Please tell me what kind of bombs more than the developed “small diametric bombs” planning for the F-22A and F-35A?

    first, i get the impression you aren’t impressed with SDBs. If so, you are sadly mistaken. These are the future of CAS. Obviously there will be situations that call for other weapons, but the SDB is very formidable.

    It is formidable indeed. One of the most common types of munitions used these days is the 500-lb GBU, and the vast majority of those targets could be taken out by a much smaller bomb at this level of precision, while reducing the probability of collateral damage. Additionally, the SDB can penetrate much like a 2000-lb BLU-109, it has fold-out wings that extend its range to more than 60 miles (even longer when launched at high altitude and speed from an F-22), and it can incorporate a thermal seeker for mobile targets (GBU-40).

    F-22 – 1000 lb JDAM, WCMD

    With regard to 1000-lb JDAMs, the F-22 can use both the GBU-32 (Mk 83 warhead) and the GBU-35 (BLU-110 warhead). In addition, its four wing hardpoints–all of which are capable of carrying heavy loads–are wired for smart munitions. Although there are no current plans to clear the carriage and launch of external air-to-ground weapons (just additional AMRAAMs along with fuel tanks for now), the potential is there for it to be developed into a very capable strike platform with only minimal modifications.

    You can´t only look at the stealth capability as your insurance which only is functional in the frontal aspect
    Irtusk: F-22 has all aspect stealth
    Roffe: Are you quite sure?

    yes

    it’s not equally effective from all angles, but it’s still ‘stealth’ from most angles

    Due to planform alignment, the F-22 has four major lobes (in roughly the shape of an “X”) that result in potential radar “glints”; these are mitigated as much as possible using RAM and RAS, I’m sure, but this is the major weakness in its stealth capability. However, these glints are narrow enough that even momentary detection by enemy radar would be very seldom, as well as largely avoidable since the situational awareness picture presented to the pilot shows him intuitively all he needs to know in order to remain undetected. The F-22’s stealth is best at the front, but from all other aspects, aside from the glints, it’s nearly as good. And even if the RCS of the side and rear aspects is several times that of the front, this translates to maybe a ~30% increase in detection range, which is still probably at the WVR level for typical fighter radars–most likely you’ll see the F-22 before your radar does.

    To sum up all questions in some cases is a matter of taste if your Defence Force has an unlimited quantity of money – but to send a $265 Billion aircraft in a warzone piloted by only one pilot without possibility to equip the aircraft with an operator don´t feel me satisfactory, especially when there already are cheaper and fully competent multi role aircrafts on the market as more are suited for strike roles.

    The world is in a constant state of change, and combat is no exception. Newer SAM systems have made even the best non-stealth fighters too vulnerable, and some of these otherwise highly capable fighters are available to just about anyone. In recent decades, the USAF has not had to face the best that the rest of the world has to offer in combat, so they can’t afford to be complacent and expect that they will always have the same level of success.

    Regarding the cost of the F-22 specifically, I see different numbers quoted by different people for different purposes at different times. All I know is that while it is relatively expensive, the more the USAF buys, the cheaper each unit will get due to economies of scale that have not yet been realized in this case. They believe that it’s worthwhile, and so do I.

    Anyhow four eyes are always better than two even if your plane is automatic superintended by a skilfully crew via data link at the other side of the globe.

    Aren’t six eyes better than four, though? Why do you settle for just two crewmembers when three can accomplish more work or constantly scan more of the sky?

    Every second you can’t be commanded from a another place when a threat is going on but of course there are many situations I suppose a pilot workload better can be solved with a support. Despite that a pilot eye is better used together with an operator using his AESA, IRST, NCW.info, internet protocols a.s.o.

    You’re always so concerned about operating sensors like the AESA radar, but in reality the F-22 and F-35 operate the radar for you. For the most part, you just choose which displays you want up and set the EMCON level, and the avionics will give you a coherent picture of the combat zone. Pilots don’t have to worry about how it’s actually done or which sensors are being used, and can focus on the more important tasks that require his attention.

    To avoid close dog fight an operator is the best assurance for a survive, I am sure.

    I’m not sure what you mean. The pilot still needs to have a visual sense of where he needs to fly in order to avoid dogfights. That’s what his tactical screens will show him quite intuitively at a glance, with no manual operation of the sensors necessary. It’s different from previous generations of fighters.

    F-22A and F-35A are stealth in some angles in the front aspect

    As pointed out above, the F-22 has all-aspect stealth. I assume that the F-35 is similar but do not yet have confirmation, so I can’t comment on that right now; it’s probably a safe bet that it does have all-aspect stealth to a high degree, though.

    but to fly such an expensive aircraft and only trying to point at your foe seems for me funny like those times when a pilot was searching up headings for Doppler-Zero to avoid to be hit by this age missiles during the 80th.

    No, all you have to do is avoid the engagement envelopes of enemy systems, and maneuver into favorable positions for attacking them. All of the necessary information is presented graphically on a single display. You don’t have to look at a strange (aren’t they all?) RWR display and mentally interpret and integrate that information along with data from various sensors in order to formulate your tactics. Just imagining having to go through this process during the heat of combat almost makes me feel anxious, but it’s a lot easier in the F-22 (and I would think the F-35).

    According to the small diametric bombs – how effective are they as bunker-bombs?

    They can penetrate 6 feet of steel-reinforced concrete, and even more deeply into softer material. The explosive effects are limited, obviously, but it doesn’t usually take much in such an enclosed volume once the penetration has occurred. And its fuse has a number of different modes for different classes of target, of course.

    If F-35 A2G can carry six 200lb bombs – why use them on a so expensive aircraft? You can’t be stealth in close air support or in dog fight!

    They shouldn’t have to dogfight once the F-22s take care of enemy air defenses and fighters. If, however, the situation is less than ideal, then they’ll have to carry fewer large bombs internally and/or SDBs, but at least they are far more survivable in this mode of operation. Stealth gives you options, not limitations.

    A look with your eyes in the HMD and a press on the button for an IR missile is sufficient and you can do it from a well IRST equipped F-86 Sabre or likely.

    Why should anyone buy Gripens, then, when a much cheaper F-86 would do?

    Having a 2nd person in the cockpit comparing having a pair with only one pilot each in the sky – what do you prefer?

    I’d prefer three or more, but in the big picture, it’s not worthwhile, and with the automation that can be done today, two is no longer worthwhile, either, for most missions.

    Why not use two-seaters but use the second with only one pilot (the second place empty)? You can in any case handle free after the threat and you always are able to use the best. With F-35A you always have the best but without an operator – do you understand my point to procure two seat aircrafts?

    I get your point, but then the aircraft would have to sacrifice something, such as range.

    The project which can be translated as Multi Purpose Fighter (MFI) started in 1981. According to some data in 1989 the prototype was practically ready.

    Here is a fairly informative page on where this project stood as of 1997:

    http://aeroweb.lucia.it/~agretch/RAFAQ/MiG1.42.html

    The engine should have been AL-41, with afterburner trust of 20 000 kgf. The engine was the state of the art for its time, but designing not absolutely complete.

    The latest information I have is that its development is still not complete. Sukhoi wanted to use the AL-41F on the Su-35BM, but settled for a highly developed version of the proven Al-31F instead. The AL-41F is still slated for the Su-34 in the future, but will most likely be derated, at least initially. Performance in terms of parameters such as throttle response and thrust/weight is said to be tremendous, but the problems have always been with the wear and longevity of critical parts when running at the higher thrust settings.

    There is also information (as was stated above) that there is another prototype except the demonstrated 1.44 and it is still quite classified (people who know things about this second prototype say this).

    This must be the mysterious 1.42. In the linked page above, it seems that MiG engineers were testing a whole bunch of design configurations to see what kind of aerodynamic performance they could get out of low-RCS shapes. What the 1.42 itself looks like seems to be completely unknown to the public.
