    the F-111 has 2 swiveling and 1 non-swiveling hardpoint under each wing. One of those pylons can also carry an AIM-9 in addition to it’s normal load. the outer, non-swiveling pylons prevent the wing from sweeping past 26 degrees. It’s kinda neat to see a FB-111 take off with 6 tanks with the outer 2 already pointed in.

    It’s AIM-54 Phoenix missles are carried on pallets between the engines (4 missles). The 2 hardpoints on each glove vane will carry another Phoenix/AIM-9 or AIM-7/AIM-9 or 2 AIM-9 combos for a total of 8 missles. That’s typically enough for the types of engagements the Tomcat was designed for (shooting down Soviet bombers and/or any escorts).

    Have any “F/A-18 E/F Transonic Flying Qualities Overview” report?

    It will be interesting to know what is core of transsonic wing-drop problem…

    Would the KC-330 take CF6 engines? I would imagine that the USAF would demand that engine to ensure commonality since that engine is already used on USAF KC-10, E-4, VC-25.

    And why not?
    Most of the fighter bombers need a navigator – it started with the F-4.
    Just for another pair of eyes I will take a two seater.
    There is actually a great story about the evaluation of the Phantom before been bought by the IDF/AF. In that time the IDF/AF prefered single seaters, so they thought about asking the US to develop a single seater F-4 for them.
    Beni (Benyamin) Peled, the AF commander at that time, sent a group to the US, and he told to one of them – “I’m sending you to see if there is a need for a navigator in the Phantom – and the answer is better be ‘no’ “.
    In the end they understood the power of the navigator in a fighter bomber like the F-4, and since then the Israeli fighter bombers are mostly two seaters.

    Don’t get me wrong… I wasn’t criticizing, just commenting. I believe the IAF is the best, most professional airforce in the world (yes, above the USAF- and that’s coming from someone who grew up in the USAF).

    Good idea that’s already in the works. It’s called LADAR.

    Is there any nation that puts more effort into using 2 seat variants in cobat roles than Israel? Almost every picture I’ve seen of IAF aircraft are 2 seaters. 😎

    In the US, when the interstate highways were being built, there was a specfication that 20 (IIRC) of every 100 miles of interstate be perfectly straight, level and free of bridges/overpasses to be used as a runway in the event of a nuclear strike took out all the available established airfields. I’ve also seen reports of massive fields of concrete buried under farmland in the plains states (the one I saw was near Altus AFB, Oklahoma) that could be uncovered and put into operation as airfields.

    no my friend lightndatic
    the Suko will keep climbing AND accelerating AND putting more and more distance from the enemy (remember t/w superior to 1)
    its the other airplane that eventually will run out of power and will give up as you see on the diagram
    remember i’m just trying to interprete the idea behind the figure, that’s it, by the way this figure does make a lot of sense to me, that’s all 🙂
    kool posting by the way, thanks 😎

    Your explanation makes sense if you’re running from an F-4 or F-14/15/16/18 heavily loaded with A/G ordinance as those aircraft and weapons loadouts prevent accelerating vertically. Otherwise, any 4th Gen fighter can hang with the Sukhoi in the vertical long enough to get a shot off while the Sukhoi is at max AB (T/W ratio is at Max AB, remember) trying to get away.

    My second assertion is that the Sukhoi can’t slow from a max effort climb into this stall maneuver in time to still hit an adversary that can’t climb with it and desides to extend. It either has to commit to the stall maneuver early enough into the act (which would give the pursuer the time to use the appropriate counter) or stick with a full power ballistic escape run (and he better be popping flares like a madman if he hopes to have any chance). I just cannot see where this show trick would work against a competant pilot in a 4th generation fighter. See my diagram modification:

    i believe that, what the diagram means is…
    the Sukhoi because of its thrust to weight ratio will outclimb the enemy to escape (even western pilots with that kind’a power do so) and when the enemy abandons the vertical pursuit…BANG an R-73 is right behind ready to blow.
    the problem for the enemy would have been trying to engage the Sukhoi at that speed and altitude to begin with.
    like going to fight at the enemy’s own arena (not a clever idea 🙂 )
    Camaro.

    The problem with that is that once the Sukhoi commits to a vertical power climb, he’s still a sitting duck for anything but a gun shot. I know there’s nothing I want to see than a max power climbing target if I’ve got an AIM-9 to spare. In that attitude, he’s putting out tons of heat, not accelerating as fast as if he were in level flight, and not able to maneuver as sharply as he could in a horizonal plane.

    The way I see that diagram is the Sukhoi commits to the maneuver as he pulls the nose up. He’s gotta be shedding speed in order to force the overshoot. Once you see that HUGE speedbrake pop and the nose come up, you also pop up into a yo-yo and once you’ve come over the top of your loop, there’s the Sukhoi, low speed, nose down, likely trying to accelerate way from you with his behind sucking up his seat cushion.

    Whoops, I forgot to do my ‘I’m a new guy’ thread. I too have been lurking for a while and decided to jump on into the pool.

    Inside sources? I doubt anyone would ever talk about anything on the B-2. Quite risky business it is.

    I was joking about the inside sources. 😀

    The first 3 aspects of stealth SHOULD preclude the need for this tech, though. Even though the beam is tightly controlled and focused, it’s still detectable and it’s use should be sporatic at best.

    The tech about the B-2 that truely facsinates me is what do they do to control contrails?

    Good points, I think a airship could be fitted with alot more defensive systems and weapons than a Hawkeye as the weight penalty would not effect performance in the same way as a heavier than air platform.

    I guess if you’ve got enough power to run a long range radar, in times of emergency, you could shut it off and re-direct power to engines or jammers. It still seems dicey, though.

    Lightndattic, I take it that you believe that active radar cancellation is not in use with the B-2?

    I know it’s possible and understand the physics of it, but I’m not aware of it being an operational system on the B-2 (my inside sources have not reported as such 😀 ). Now the AESA upgrades do allow jamming via the radar arrays, but again AFAIK not active cancellation.

    To me it would be unwise to use such a system on a L/O platform simply because it is an emitter. With fequency agile systems, you’d be hard pressed to keep up with the jumps and you’d be blasting your position to any type of bystatic radar or even AAMs with an anti radar backup.

    The can only see 2 snags of said airships: Vulnerability (at least a Hawkeye can run) and the time it would take to get on station or re-position on a threat axis. As long as you’re going to have a large carrier with cats and arrestor gear, you might as well have an AEW platform that uses those facilities.
