Going high or fast was never something revolutionary. However it does work. Many times MiG-25 was attacked by Israeli F-4s, same generation fighters of its era, and it proved very difficult, almost impossible to shot down. MiG-25RBs simly flew on top of F-4s, in a sense “punching through” (by dodging) everything they throw at them. Only after Israeli got F-15s, MiG-25s start to go down. Even F-15s were not always succesful in intercepts, there are occasions MiG-25 dodged all 4 BVR missiles fired by each F-15 and ran away. In desert storm, first air to air kill was a MiG-25 shooting down an F-18, which was 20 years newer and quite possibly better maintained and better piloted.
If those Mig-25s had penetrated defenses and shot down a high value target then I might agree with you, but with the exception of the F-18 shootdown over Iraq they generally only succeeded in that they were not shot down themselves. There is no doubt some value in harassing your opponent but generally you can’t declare success based simply on the fact that the Migs were often able to escape the engagement alive.
All of this tells me going high/fast and having big, long range missiles actually works, and works very well.
One kill against an F-18, and one against a predator falls well short of what I would consider working very well, especially given that several Mig-25s were also shot down over their operational life.
IMHO a well maintained and piloted MiG-25/31 is still a big threat to all 4/4+ gen fighters, simply because a) they have means to shoot their targets at longer ranges b) their targets have no effective means to shooting them down (AIM-120 historically didnt work so well)
They are a threat, certainly, but nothing in their operational history suggests they are any greater a threat than other fighters of similar vintage. You can point to the AMRAAM’s success rate in combat, which is excellent by any reasonable standard, but where is the track record for the Mig-25/31?
“Hit succesfully with high Pk” should be more correct. There are many other things to consider. First and most obvious is, a missile does not need to hit its target to be effectively kill it. AIM-54 with 61 kg HE warhead needs only to get within ~25 meters of an aircraft to kill it. An AIM-92 with 3 kg warhead, for example, reqiures direct impact to detonate. Even with higher G capability, its doubtful a Stinger will be a more effective than Phoneix to a highly maneuverable aircraft.
Actually most 4th gen can pull 9Gs at 30k, however at what energy cost? Its -2400 fps for an F-16 with 6 AIM-120s. How long can it sustain such G levels? Probably less than 2 seconds. So pilot would be trading altitude to maintain airspeed, hence high G ability. By the time pilot has dodged a BVR missile, he would have lost 15k altitude and some airspeed, his situational awareness, jetissoned his fuel tanks and mission payload (if any), and enemy still has target lock and able to fire the second missile. With afterburners lit enemy is in an even superior energetic position, closed in so his missiles are more effective. If the victim dodges the second, he would be in such energy state he wont be able to pull high Gs or escape. Thats why I find it ridicolous to dismiss any BVR missile, especially the longer ranged AIM-54 or R-33 and similar types.
Can a single R-37 shoot down a Eurofighter? Possibly no. Can 4 R-37 missiles shoot down a Eurofighter? Possibly yes. Same goes for any missile/aircraft.
The other issue is that missile guidance logic is smart enough to lead a target even if they are turning. A jet pulling a steady nine-Gs will be a more difficult target than one flying straight and level, but that does not necessarily require the missile to be pulling significant Gs in the final moments before impact. If the guidance logic is working as designed the missile will lead the target such that so long as it continues to pull a steady 9Gs the missile will only need to make very minor corrections in the moments before impact.
Most of this is the same old same old, no real reason to rehash yet again.
I do find the wing loading chart somewhat amusing as it shows the F-4 beating the F-16 and the F-15 beating the F-22. (It also leaves off the F-35C :eagerness:)
Seems to suggest there just -might- be more to maneuverability than wing loading….
The PAKFA most likely flies much longer, Faster, is stealthier, and has better sensors. As far as weapons, new weapons will slowly start to trickle in as the jet approaches IOC and then grows further (just like we’d be doing with the NGJ)…Speed and range here is what its biggest capability in my opinion. Besides the F-22 (production of which has ended – and wont come back) there arent many fighters out there that can give you very good range at a mach 1.6-1.7 cruise speed (Thats what i expect the PAKFA will deliver)…..Heck the F-35 can barely get there with full Afterburners and that too after exhausting most of its range.
The reduced RCS will help, as will the improved sensors, speed, etc. My point is that this really isn’t a new problem. Forty+ years ago people were talking about more or less the exact same threat, only then it was the Mig-25 with its improved speed, sensors, and huge fast missiles. I am not saying that the PAK FA isn’t an improvement over the Mig-25, only that this is one more notch in the steady improvement we have seen for decades, not a revolutionary new type of threat.
If we follow Shaw’s simple formula, then a missile that has lost speed so it is only able of pulling 20g,
can at best engage a fighter doing max 4g at 30.000 ft.
If OTOH a fighter can pull 8g at 30.000 ft, then the missile has to be capable of at least 40g.
For starters, no BVR missile can do that, but they can plink down a fighter doing 4g,
a cutting edge WVR missile can take down an 8g fighter at 30.000 ft at point blank range.
It was never disclosed at what altitude an amraam could pull 30g, but i’m betting it was at low alt., since it looks twice as good on paper.
ed: to expand on BIO, T-50 need much less safety margins while bypassing defenses.
:very_drunk:
Spare us this “BVR missiles don’t work” theorizing… we have thoroughly debunked it over and over and over again.
I think he used PUNCH THROUGH analogy to show that the PAKFA will look to penetrate the defensive cover that usually surrounds integrated air forces. Breaking past the fighter, ISR cover to get within range to lob LRAAM’s towards strategic targets…
Certainly, I just don’t get the fascination with the size of the PAK FA or its missiles. A Eurofighter with Meteor presents a similar and arguably greater threat.
Its a Russian_F-22, with unique russian requirements, and based on their force structure. They want Long range, Speed is a pre-requisite for any 5th gen air defense fighter, and the russians are always uncompromising on brute maneuverability and 3d TVC….It would also have BIG RADARS, probably all over the airframe, as well as other antennas (such as the L band wing mounts) just like the F-22. Its the Russian Air dominance fighter.
Of course
They want a big fast maneuverable plane that can go a long way. They also want a reduced signature airframe relative to their previous designs and improved sensors. I don’t think anyone debates that.
Everyone thinks they are right. That does not mean that everyone wants others who disagree to be dead. If a Christian minority lives in a Muslim majority country, my understanding is that that community can practice her own laws within their community. That is respectful and the proper thing.
And what happens when a Muslim decides to convert to Christianity? Or decides that the “Prophet” Muhammad was just a 7th century warlord with no special insight into the workings of the universe?
Islam is not a religion but a complete way of life. It is an economic system, a political system, a social system, a legal system. In the lands that are majority Muslim, it is fair for Muslims to demand those systems to come into place. We have even won elections to that effect but in every case, by Western support of small secular elites, who control the post-colonial army and administration, we’ve been thwarted.
That is exactly the problem. Once the Christian world was characterized by the same primitive worldview that placed the Church at the center of public, private, and political life. Over a long and painful process it has for the most part found ways to move forward. 1,000+ year old texts are no way to run a society.
Who or what many Islamists say or think, you don’t really know. You just know what the media tells you or how it portrays small numbers of highly extreme people, who may even be in the pay of another (for instance Adam Gadhan).
Sure… :rolleyes:
We all know the PR version, and we are also all familiar with the newspaper headlines.
A Muslim by definition cannot be an extremist – the Quran clearly states:
“We made you to be a community of the middle way, so that (with the example of your lives) you might bear witness to the truth before all mankind.” (Qur’an, 2:143)
Oh good, I guess all you need to do is call up all those guys killing people in the name of Islam and let them know it is time to knock it off. :eagerness:
I just think that this forum would be the better without these periodic jibes at Muslims, in this very thread you have examples of how excellent the secular and Western views are – calling to destroy the Ka’aba and the Vatican and calling to turn the Middle East into glass. Those statements here are not made by Muslims, so you can see first hand who the extremists are.
Britain, Germany, US and the West in general has done far more harm to humanity than anything we Muslims may or may not have done. http://www.ae911truth.org/en/about-us.html
I did not start this non-aviation related controversy, but we will not stay silent when you attack and insult us, and attempt to marginalize us by labeling us in your own preferred hues.
Britain, Germany, the US, and the West in general is the primary reason the modern world we know today exists at all. From space flight, to antibiotics, to the internet, to automobiles, aircraft, etc etc, all were primarily the product of scientific and engineering progress in the West, Russia, and Asia. That isn’t to say that anyone is without fault, but the idea that the world would be better off without the West’s contributions is ludicrous.
I find the idea that a plane is going to “punch through” its opponents by virtue of its large size and speed amusing. This isn’t Rugby people…
A PAK FA will likely be just as dead from a Meteor/AMRAAM as a Mig-21 if they take the hit, and no, a PAK FA is not going to somehow “punch through” (whatever the heck that means) while dodging missiles the whole way. To the extent a manned fighter can dodge missiles at all it is only something that can be done at longer ranges. Closing that distance ensures you will eat a missile.
I agree that the PAK FA’s range and speed will be valuable and that it would likely be tasked with trying to find opportunities to engage high value targets, especially given the PAK FA’s likely small numbers, but that is easier said than done when dealing with the US/NATO. Protecting high value airborne assets is something they have been working on for decades and practice in most major exercises.
This isn’t really any different in concept from what Mig-25s were supposed to be able to do. Those are also very large, very fast, aircraft with very large missiles. (Of course in the end that didn’t make much difference.)
My favorite part:
The smaller AGM-88 anti-radar missile and AIM-120 air-to-air missile are the American analogues of the new Russian weapons. Both several feet shorter and hundreds of pounds lighter than their Russian counterparts, the U.S. munitions reflect a specifically American air-warfare philosophy. American stealth jets including the B-2 bomber, the F-22 and the still-in-development F-35 carry relatively small, lightweight weapons with short ranges.
This is a Massive Ordnance Penetrator:

That is 30,000lbs (13,600kg) of “relatively small, lightweight” bomb. :rolleyes:
Agreed
He really is just terrible… anyone on this forum that can’t find numerous holes and errors in this article needs to find a new hobby.
http://www.flightglobal.com/blogs/the-dewline/2010/05/aviation-week-suspends-bill-sw/
Yep. Nothing to see here.
Bill has become a lot more careful with the “attorney speak” where things “might happen” or “maybe won’t” He makes sure to post under names that are not his on forums. Forums where he hasn’t already been outed and crushed before withdrawing that is. So while “Bill Sweetman” has been very careful with a kind of passive-aggressiveness that a even a mother-in-law would find extreme at his professional publication, “Low Observable” has been much more direct and upfront in his criticism of the JSF.
That bit about the mother-in-law could have cost me a keyboard had I been drinking while reading your post. Note that I never said that it certainly would have wrecked my keyboard, only that it might have. :eagerness:
As long as we are talking about things that are “technically defamatory.” I would like to point out that technically, everything Low Observable says, is what Bill Sweetman says as they are one in the same. Pseudonyms aside. Technically the law does not see a difference from your internet handle, (or any other aliases) and the person actually posting. So I would be careful about getting “too technical” there, Bill. Though I would love to see you seek restitution for the technical defamation, and force the whole thing to played out in court with all evidence available publically about who really said what between you and your internet personalities, and if Fed did in fact break the law.
Are LO and BS are the same person? I suppose they might be. Naturally I am not saying that they are, just that that is one theory that is out there. 😎
I would suggest that it would make a lot of sense if they were given the one’s fascination with trying to salvage the reputation of the other. Of course I am not going to say they are the same guy.
You can’t say that I said that.
:eagerness:
And so the saga continues, as Jackster combs the Interwebz in search of something that isn’t there, Hopsalot asserts that not saying that “cats cannot fly” means that you are saying “cats can fly”, and Fedaykin sulks in his tent rather than admit to making an assertion that was false and technically defamatory.
Sure LO, you are the one guy who can’t figure out what was being said in those blog posts.
It should give one pause when they find themselves choosing between playing dumb and admitting they were wrong. Not that I am saying you were wrong or anything, but I would suggest that you might have been. :rolleyes:
…and don’t you dare come back later and accuse me of having said you were wrong. I never did that. :eagerness:
http://www.urbandictionary.com/define.php?term=Lamesauce
I am well aware of Mr Sweetman’s existence, as it happens. I don’t think he has ever said or written that the JSF exhaust would melt decks, which is why I asked for a direct quote and citation and why I am not surprised that your only response is bluster.
As for you, Jackster, learn to read. I did not say that JSF critics had not advocated cancellation, but that they had not predicted it (which is what your original snark hinged on). Clearly some of the realists have called for the project to be scrapped, and indeed if the real story had been told in 2008-09 it should have been.
Continuing with the farce where we don’t know who you are for a moment…
BS is generally fairly careful how he words things such that he can imply the sky is falling without quite going on the record saying so.
On the subject of melting decks BS contributed this blog post a couple years ago:
Gore goes on to list the “unrelenting tide of good news” about the F-35. He does this by getting the good news wrong and leaving out the bad news.
“The STOVL variant, the F-35B, is about to emerge from the probationary period imposed on it by then-Secretary of Defense Robert Gates.” The probationary period was two years, imposed ten months ago. The Pentagon could rescind it, but I don’t see any signs of that happening, or of more F-35Bs being added to the LRIP stream.
And Gates’ words at the time — that the F-35B was “experiencing significant testing problems (that) may lead to a redesign of the aircraft’s structure and propulsion” — still don’t sound quite like “show me it can land on a ship and you’re good to go”.
“Remember the critics who warned that the exhausts from the STOVL JSF would melt deck plates?” No, Dr Goure, I don’t remember anyone saying that. Could you remind us, with sources? The Navy and DARPA have spent money, and indeed continue to spend money, because of concerns that the combination of exhaust heat and blast could cause fatigue over a ship’s lifetime and force costly repairs.
Test data from last month might have shown those concerns to have been overestimated, but we don’t know that yet.
[Emphasis added]
So here we see BS operating at his finest. He doesn’t say the F-35 will melt decks, only that we don’t know yet that it won’t. The insinuation is clear.
Here is BS’s original, now infamous, blog post where he compared F-35Bs to “anti-runway weapons.”
In operations around Marjah in Afghanistan, the Marines have been using AV-8B Harriers as they were designed to be used, flying the jets from runways that are too short or ill-prepared to accommodate a conventional fighter. Kimberly Johnson is reporting on this for DTI’s April issue.
…
But a Navy report issued in January says that the F-35B, in fact, won’t be able to use such forward bases. Indeed, unless it ditches its short take-off, vertical landing capability and touches down like a conventional fighter, it won’t be able to use land bases at all without some major construction efforts.
The newly released document, hosted on a government building-design resource site, outlines what base-construction engineers need to do to ensure that the F-35B’s exhaust does not turn the surface it lands on into an area-denial weapon. And it’s not trivial. Vertical-landing “pads will be exposed to 1700 deg. F and high velocity (Mach 1) exhaust,” the report says. The exhaust will melt asphalt and “is likely to spall the surface of standard airfield concrete pavements on the first VL.” (The report leaves to the imagination what jagged chunks of spalled concrete will do in a supersonic blast field.)
…
This follows the revelation that the US Navy is worried about the exhaust damaging ship decks.
Lockheed Martin pooh-poohs the report, saying that it was based on “worst-case” data and that “extensive tests” conducted with prototype BF-3 in January (after the report was completed) showed that “the difference between F-35B main-engine exhaust temperature and that of the AV-8B is very small, and is not anticipated to require any significant CONOPS changes for F-35B.” [I do find it amusing that BS described the refutation of the report by the people with the hard data as “pooh-poohing.”]What do “very small” and “significant” mean? In VL mode the main engine on the F-35B is producing some 15,700 pounds of thrust, while a Harrier’s aft nozzles deliver about 12,000 pounds of thrust. (The fore-aft split is roughly equal.)
But the F135’s overall pressure ratio is almost twice as high, which would point to a much higher jet velocity (which LockMart doesn’t mention), the JSF nozzle is much closer to the ground, and the Harrier has two nozzles, several feet apart.
So maybe the F-35B is not shaping up to be the best anti-runway weapon since the RAF retired the JP233. However, it may still not be what the Marines got when they first acquired the Harrier in the early 1970s.
So here we go again, “maybe” the F-35B isn’t shaping up to be the best anti-runway weapon since the RAF retired the JP233… maybe. Maybe there will be “chunks of spalled concrete in a supersonic blast field.”
He can claim he didn’t say the F-35B would melt decks and spall concrete. He can write a blog post where he goes on and on with a simplistic leading argument about the F-35B’s increased thrust, etc, compared to the Harrier and then conclude by saying the F-35B “maybe” isn’t shaping up to be an anti-runway weapon. :rolleyes:
For another example of a critic claiming that F-35s would melt flight decks see here:
http://www.theregister.co.uk/2009/11/17/darpa_chilled_landing_pads_for_osprey_f_35b/
It’s now official. The new generation of high-tech hovering aircraft – namely the famous V-22 “Osprey” tiltrotor and the upcoming F-35B supersonic stealth jump-jet – have an unforeseen flaw. Their exhaust downwash is so hot as to melt the flight decks of US warships, leading Pentagon boffins to look into refrigerated landing pads.
Naturally the above wasn’t contributed by a critic… or not a critic that counts anyway… because we know no critics claimed the F-35 would melt decks. :rolleyes:
Another example of a critic being wrong, and from BS again no less:
So whatever the F-35B propulsion and structural problems are, they have to be solved without adding weight. At the same time, changing materials and redesigning components will further reduce commonality between the B and the other two versions, putting upward pressure on costs for what is already the most expensive version.
I suggest the sharp brake that Gates has put on production does not speak to a high level of faith that it can be done. It suggests that the decision to put the STOVL jet on probation, rather than sending it directly to meet Old Sparky, may have been driven by concern that killing both the F-35B and the Expeditionary Fighting Vehicle was a political impossibility, and by a desire to minimize political impact on the entire JSF program.
The next developments to look for: the outcome of the review of Marine Corps force structure, and the scale and type of resources that will be made available to fix the F-35B.
Once again, BS doesn’t -quite- say he thinks that the F-35B can’t be fixed and will be cancelled, but he “suggests” as much and argues that the only reason it hadn’t yet been cancelled was because of politics. :eagerness::rolleyes:
Because Rafale/Typhoon aren’t VLO and are smaller aircraft than F-35/SH or the proposed alternative?
Mind you, USN buying into Rafale instead of Super Hornet makes for an interesting alternate history scenario…
Not a chance… The Rafale is substantially more expensive than the Super Hornet even while trailing it in capabilities.
Sorry but starting with a better airframe (F-14) would have allowed a better lifetime upgrade and enhancement path. Instead of a SH, imagine an F-14 with a integrated weapons bay integrated into the tunnel between the engines, conformal tanks where the externals were and Aim-9 pods under the gloves and honestly tell me what the more capable platform would be.
Yes, the boat has sailed and there is no going back, but the wrong plane was chosen.
Wrong plane? Absolutely not… the Navy needed a lot of things from a new fighter, and one of the biggest was low cost.
What you are saying is the equivalent of saying that the USAF should never have developed and bought the F-16 and should have just bought F-15Cs for air to air and F-15Es for everything else. “Wrong plane” That never could have happened of course because the F-15 is just far too expensive to have been bought in the necessary quantities and it doesn’t particularly matter anyway because not every mission requires an F-15.
Your argument against the F-14 would also lead to the F-15 and F-22 also being no longer needed as the role they were designed for no longer exists either.
Exactly, and that is why the F-22 program was cut short. It is an amazing plane, but most of its reason for existence has disappeared. It seems likely with the PAK FA and J-20 that we will see a 6th generation fighter to replace the F-22 and the remaining F-15Cs but right now there is just no pressing need for more F-22s.
