    "F-22 raptor " to India ?

    I do not get personal as you may have already noted. If this is not flame-baiting, then what is, I wonder!

    Please go ahead and make a clean breast of yourself. No philosophy here. This is a bulletin board; not only members but 100s of guests also read various posts. Somebody or other surely will engage with me if they disagree. As for being an expert, I am not propounding any new theory. All these...

    If you have any reservation, you can debate and counter me. I never make any post to win an argument nor DFI gives any prize to the winner. :)

    "F-22 raptor " to India ?

    Both IRST and IR homing are same. Both track the target from its heat signature. Both are passive sensors meaning they do not emit any signal unlike AESA radars or DIRCM. IR sensor on missile is mounted on nose, (see the image of Nag) or they can be gimbal mounted to look sideways..these kind...

    There are fire and forget missiles. These missiles have on-board seekers (IRST) which home in on targets. US's much acclaimed anti-ship Harpoon is one such. Back home we have Nag anti-tank missile with own guidance. Pilot intervention of fire-&-forget missile is possible upto some distance ( See...

    "F-22 raptor " to India ?

    VHF radars can't be mounted on plane. They have tall polls for antenna. They will be ground-based but can "talk to" pilots to give input. Another minus is VHF signals are noisy, indistinct and full of clutter in lower atmosphere. Plus point is long-waves of VHF can reflect back faithfully from...

    IRST provides top-class missile guidance and homing..in fact in the terminal stages, all missiles use the infrared camera to lock onto the target. VHF, I agree cannot be an airborne radar because of its antenna size.

    I see qwip more as a photodetector than heat detector. Heat detectors use IR devices in the short and medium spectrum of IR radiation--invisible). Qwip uses longer & cooler IR wavelength which is near-visible; otherwise the entire infrared spectrum is distinguished only by wavelengths, each...

    For every counter-measure, there is counter-counter-measure. Jammers, anti-radiation missiles, towed decoy radars have not rendered on-board Radars in fighter planes useless.

    Seekers in missiles are also IRST..qwip can not be categorised as an IR sensor.

    "F-22 raptor " to India ?

    You are right. When two stealth fighters engage, the detection will shift from RF to IR signature. F-22 junked AIRST to save money, but Pak Fa will go ahead and have it. At the same time, there is nothing to presume that if India buys f-22, it is to engage in a duel with Pak Fa !! Pakistan will...

    Ha.. i saw it in several places on this forum & PDF. So thought most members knew the source !

    The main problem in maintenance of Raptor is the stealth coating. It degrades easily and has to be redone frequently. I dont know any other major hardware problem F-22 is facing. Please provide link..I failed to find any.

    "F-22 raptor " to India ?

    Which sensor it is? F-22 has AN/ALR-94 passive radar receiver system, made by BAE systems, capable of detecting the radar signals in the environment. Composed of more than 30 antennae smoothly blended into the wings and fuselage. With greater range (250+ nmi) than the APG-77 AESA radar, it...

    Lol....no body took the image seriously. It was just usual bulletin-board bantering. Btw, JF-31 looks entirely different in reality.

    "F-22 raptor " to India ?

    Proponents of Pak Fa point out that Raptor doesnt have 3d trust vectoring nozzle and its APG-77 radar has only 250 km range against Pak's 400 km, that Raptor lacks IRST etc. But both boeing & Lockheed Martin are quietly upgrading avionics to ensure that at any point of time Raptor will be a few...
