    You might believe it to be a joke, but the prospect of a missile swarm overwhelming CVN defenses terrifies the USN. It is a real threat. And it works against IADS too.

    Maybe on paper…
    In the real word, if some fluke shot doesn’t happen, a CVN should (and probably can) withstand a large number of hits by the Harpoon sized projectiles.
    Sure, it will be busted, but afloat.

    However, what really frightens USN is AS-4 nuke “Kitchen”, a smaller plane sized 350kT missile, which can’t be stopped by CIWS, nor pretty much anything the USN can put against it.
    This is the real “carrier killer” and you need many Tomcats, with even more Mach5 AIM54s to stop it…and each Tu-22M3 carries, several of them.

    Presumably if the S-300/400 it’s defending is stationary, the the Pantsir will also be stationary. If they are on the move, they’re likely not firing(or reloading). The SDB II can engage moving targets.

    CIWS is designed to cope with multiple high-subsonic/supersonic, threats.
    If it can’t, it isn’t a CIWS then.
    How many slow SDBs will it take until they saturate a single Pantsyr (and there will probably be more, defending high priority target)?
    …and once they’re through the CIWS’ screen, SDBs still need to hit, which may be impossible, if the bomb is damaged when passing through the screen, or just simply miss, or…

    The point was that at some point, the number of incoming bombs is > than the available number of outgoing missiles. This works in pretty much whatever scenario you want to use, where tactical aircraft are performing SEAD/DEAD missions.

    Yes well, at some point you get to sink a CVN with enough kamikaze Mig21s attacking from opposite directions…the question is where will you find enough “volunteers”? 😀
    If you need to use an entire squadron each time you go for a double digit SAM battery, you won’t get very far fighting that way…especially if some of the planes get shot down.

    So, once you start to use saturated attacks, the point of “cheap” fighting (using SDBs) goes down the drain and a few well placed high-speed ARMs, would probably do a job much quicker, cheaper and with much less resources invested in the sense of flight hours (no. of planes) and all following expenses.

    A bomb has a much higher likelihood of hitting a stationary target, than a missile does hitting a moving target(especially when EW/EA is being used).

    And Pantsir is stationary target??

    Again, you’ve shown a willful misunderstanding of the point. When each striker carries 8 SDBs(or more if we include legacy aircraft), at some point the defender’s ability to engage(and reload) are going to be overwhelmed.

    At what point?? Against whom??

    USAF against Albaina?! 😀
    Ww, what are you talking about??

    On the other hand, those point defenses will become quickly overwhelmed, as they-
    A- don’t have a 100% PK

    And bombs have?

    C- have a finite number of missiles vs. much cheaper SDBs

    And strike wing has infinite weapons?

    Generations aren’t “stupid” (:D) per se, but the way members of fanbrigade, use them.

    There are some things common to planes of the latest gen (whichever it is), indeed.

    I’d say, first and foremost, it’s a low aspect wing of large area, suitable for high speeds and instantaneous maneuvering at high alphas to try to solve the combat as quickly as possible,
    as opposed to previous gen, which was designed for sustained performance, due weapons (heaters/gun) tracking requirements.
    Such wings offer less supersonic drag, enabling higher speeds and F22/EF+GripenNG already SC, bringing the average combat speed to a somewhat higher level, compared to previous gen.

    As for the avionics, new gen. of fighters feature reduced pilot workload through advanced MMIs, sensor fusion and high degree of automation, as well as networked type of warfare,
    significantly rising pilot’s awareness of what’s going on around him, one of the prime factors, which gets ppl shot down.

    Due the high performance required of modern designs however, the new gen planes appear to have somewhat shorter range than their high-bypass engined predecessors, in spite of similar fuel fraction.
    Most of new gen. fighters feature modern materials in an attempt to keep the weight in check.
    Thrust to weight ratio is increased in comparison to previous gen. to cope with those large and draggy, low aspect wings and increased weight.

    Stealth plays part in the new gen of fighters, but as an element to increase survivability.
    Some chose to solve survivability through passive stealth, while others opted for less stealth, but supplemented with stronger EW suite.

    Also, the new gen. introduced TVC and operationally exploited post-stall part of the envelope, for the first time and some models are already flying using TVC.

    Well, I’d say those are major differences between this and previous gen.s of fighters, based what’s publicly available.
    Dunno…I may have forget something, so feel free to complement and I’m sure some aeronautical journalists or chronicle would do this better than me. 🙂

    What i’m not sure about is if this is a ‘Sustained turn rate’ or not..?
    By your definition, its not..

    It’s not my definition, but aeronautical.
    You’re right and many planes don’t do sustained, but instantaneous, winding down to sustained.

    John Fairley, a british test pilot discribe this at Paris airshow years back, when Viktor Pugoshev did a 360 in 10 seconds= an average 360 turn rate at 35 deg.
    I don’t know.. if this is real the G-limiter must be turned off..

    I’m assuming you’re talking about post stall turn performed by V.P.?
    The point is, the plane didn’t do 360° turn, but moved its nose by 360° and there’s a difference.
    You can point your nose anywhere you like providing you have some sort of control authority and you don’t need a lift for that, at all.
    Cobra is done at 3-4g.
    To actually turn the plane, you need to change the velocity vector of your aircraft and to do that you need a lift and a lot of it.

    If you examine the case when F22 performs 360° post-stall (J-turn, IIRC), you’ll see it does 360, but with its nose, while the actual plane does mere 270° and the plane exits the maneuver at ~90° alpha.
    This is because the plane can’t generate any more lift to turn better.

    Its just like with the Su-27PD’s doing those 360 at airshows, pretty impresive turn rate, but really.. no weapons and just wapour for fuel.. and a half de-militarized(weight reduction)..:)

    Yes, but what you mentioned isn’t a turn rate.
    Turn rate is defined as the ability of a plane to change its flight path (vector) in the unit of time.
    Neither F22 nor Su27 do that, but they spin around lateral axis while stalled and that’s it.
    This is worthless in missile combat (particularly in many vs. many), but is useful in one on one gun combat, as F22 demonstrated against Rafale in UAE, when squeezed that one kill.
    The trouble is how many such combats will an F22 actually see?

    The good Colonel does simplify every thing he says in that vid.

    Actually no and he makes false claims, which is very easily provable.

    If ANY aircraft does a ‘sustain’ 28°/sec at 20k, it would have to trade a lot of altitude. Which is excactly what the F-22 must do in a merge, just like any other fighter.

    Well, by definition a sustained turn is a turn which maintains the altitude.
    So, in order to do that, the F22 must do a 360° turn in ~13 sec, while it can’t do under 20 second on SL?!

    Now can the F-22 do 28°/sec at 20k.. my guess is it is not far from the real deal.

    It’s theoretically possible of course, but the plane would immediately stall after that.

    But just how sustained is that turn, thats my question?;)

    It isn’t.

    Most of the maneuvers at airshows aren’t at combat speeds, so afterburners are used to quickly regain momentum. Of course there is less drag at higher altitudes too.

    So subsonic speeds aren’t combat speeds?
    Never heard of that and even a 3g turn will bring F22 to subsonic, eventually if flown in dry, at altitude.
    Further, yes the drag is lesser at altitude too, but is nowhere near samll as thrust, because if it wasn’t so, then the F16’s 9g sustained envelope wouldn’t go as high as to a few thousand feet above SL, only.

    28 deg/sec at 20k feet isn’t too shabby.

    LOL, not this “evidence” again.
    I’m not sure whether you’re incapable of understanding that, or you simply won’t, but either way, that doesn’t make this any more true.
    So, let’s clear that matter, once and for all.
    For an F22 to sustain 28°/sec at 20k ft, it should be able to sustain (IIRC) ~13.5g, because its Lift/Drag ratio is about the best at M.9 (like almost all other fighters) and that’s the speed, where usually the best sustained turn is flown.
    So, if the F22 was able to sustain 28°/sec at 20k ft and let’s say at 9g, then it should be able to pull 9g sust. at M.3 at 20k ft?!
    Do you have any idea, of what you’re talking about?
    I mean this is so disconnected from brain that I think, no one but you takes those figures seriously (including that, so called, Colonel).

    Do you think that most dogfights occur at airshow altitudes, and speeds? I’m not saying the F-22 doesn’t use afterburners at all. Just that it isn’t as reliant.

    Ww, at higher altitudes, there’s even less thrust and the weight remains the same, so F22 can only use AB more frequently.

    The F-22 has enough dry thrust for maneuvering purposes, to minimize the need for afterburner though, whereas I highly suspect the Rafale would be using afterburners to keep up.

    What are you talking about?
    On every single display F22 flies on AB, particularly in sustained turns, climb, etc., just like any other legacy plane and apparently more than Eurocanards (it’s hard to say).
    How is dry thrust enough for F22 to maneuver is something I’d like to know very much, so would you care to explain?

    There is no need to invoke WrightWing. I have already had a ‘first cut’ at answering your question in postings 291 and 299 in the current thread.

    TWT has about >60% on the array compared to amplifier power output, while AESA has about 25-40%, depending on TR modules technology and that’s docummented.
    There’s what?, 10m of cable from amplifier to array and actual phase shifters in PESA are analogue LC circuits (IIRC), so I can’t tell where did you find those “lossy” wiring, but someone obviously documented that wrong??

    The fact that the paths from the transmitter to the antenna and from the antenna to the receiver are relatively lossy in a mechanically scanned radar compared to those in an AESA radar is well documented in the literature. So like the PESA set, the mechanically scanned radar has a ‘built-in headwind’ in comparison with its AESA counterpart. Some of the transmitter energy is lost before it reaches the antenna feed, while some of the reflected energy is lost along the path from the feed to the receiver.

    Yes well, but even if you somehow have a wiring with enormous dissipation (??), you can always stick a stronger amplifier to the backend of MSA or PESA.
    With AESA, there’s only as much power as your T/R modules can produce and you can’t stick 2000 TRs in a 1000 TRs space, can you?

    If the mechanically scanned antenna has larger sidelobes than an AESA array of the same physical size, that is another performance penalty. Transmitter power being radiated in the sidelobes reduces the energy available in the main beam.

    That’s true, but PESA doesn’t have that problem.
    Besides sidelobes or not, your power output and gain go down the drain at off bore angles, AESA or PESA.
    So, you see MSA isn’t so hopelessly out classed by AESA as you think.

    And the AESA radar’s ability to tailor its scan pattern (lingering on targets of interest, for example) is a performance enhancing technique not available to the mechanically scanned radar.

    That’s true as well, but then again everyone in the 300km radius will know you’re there. There’s a reason, there are numerous teams devising so called LPI techniques, to bring down AESA’s emissions to MSA levels first. 😉

    Hope this answers your questions and puts things into a bit more realistic perspective.

    This is untrue. Compared with a similar size/power MSA, the AESA array is generally credited with having 3x the detection range, due to much higher sensitivity, and more efficiency. It also offers significant advantages in jam resistance, modes of operation, etc….

    What a claim!

    Ww, why don’t you explain to us, how is AESA more “sensitive” and more “efficient”, than MSA?? 😀
    I’m VERY eager to learn.

    Appendix: And of course, how does AESA radar have 3x more range than MSA?

    You make up some preposterous statement, as if it were what I was claiming, and then proceed to attack it.

    Ww, you came here countless times with F22’s 1XX:1 kill ratio and used that as an argument to prove F22’s superiority.

    I’d love for you to show me the quotes where I’ve suggested that 2 Raptors could shoot down 20 Hornets(or anything) in a single sortie.

    Where did I say, you said that??
    The trouble is you’re taking such fairytales, as “anecdotal” evidence.

    If that happened in the exercise, it was only due to aircraft being regenerated. The thing is, Blue Force aircraft don’t get notional reloads, when Red Force planes are regenerated. This means the Raptors would’ve been Red Force, if they were getting notional reloads.

    A pair of F22 doesn’t have enough weapons to take out even a squadron of F18s, let alone 20+.
    The problem starts when some clerk adds several sorties together and all of a sudden we have figures, disconnected from brain, which guys like you read as gospel.

    I’m not even sure what point you’re trying to make with regards to the F-16.

    Unfortunately…

    Soo we use the same tactics that we used in the 2nd generation of fighter planes? Since the generation has nothing to do with the tactics are we still using guns only?

    Jessmo, the tactics isn’t written in the stone and you can’t blindly “use it”.
    It’s dynamic and changes even with the current fuel load in the plane.
    There’s no 5th gen tactics neither and F35, regardless of stealth, will not be able to do F22’s tactics simply due the difference in performance.

    Sometimes a modern fighter pilot will use the Sun to mask its approach, a trick 100 years old.
    It doesn’t mean he’s somehow “using” WWI tactics.
    This is pilot’s bag of tricks, which evolved from numerous encounters.
