    Indian Stealth Fighter – Research Report.

    Role: 5th Generation multi-role fighter.
    Manufacturer: Sukhoi & HAL.
    First flight: 2012 (projected).
    Introduction: 2015 (projected).
    Status: In development.
    Unit cost: USD $120-160 million.
    Developed from: Su-47 & MiG 1.44.

    FGFA (Fifth Generation Fighter Aircraft) is a fifth generation fighter which is being developed by Russia and India. It is a derivative project from the Su-47 & MiG 1.44 being developed for the Indian Air Force. The program is initiated to develop a fifth generation fighter aircraft to fill a role similar to that of Lockheed Martin's F-22 Raptor and the F-35 Lightning II, the world's first fifth-generation fighter jets.

    According to HAL chairman A.K. Baweja shortly after the India-Russia Inter-Governmental Committee meeting on 18 September 2008; the Indian FGFA will be a twin seater, a new prototype will be developed for India and common technology will be shared between Russia and India.

    Development - According to HAL chairman A.K. Baweja on 18 September 2008, HAL will be contributing largely to composites, cockpits and avionics. HAL is working to enter into a joint development mechanism with Russia for the evolution of the FGFA engine as an upward derivative of the AL-41F.

    By February 2009 as per Sukhoi general director Mikhail Pogosyan India will initially get the same PAK FA fighter of Russia and the only difference will be the prototype. The first Russian prototype will roll out by August 2009.

    Difference between PAK FA & FGFA - The Indian FGFA is significantly different from the Russian PAK FA because a second pilot means the addition of another dimension, development of wings and control surfaces.

    Indian FGFA & Russian PAK FA will have the common technology.

    Design - Indian FGFA will be stealthy, have the ability to supercruise, be outfitted with the next generation of air-to-air, air-to-surface, and air-to-ship missiles, and incorporate an AESA radar.

    Indian FGFA will use on her first flights 2 Saturn 117S engines (14.5 ton thrust each). The 117S is an advanced version of the AL-31F.

    Later versions of the Indian FGFA will use a completely new engine (17.5 ton thrust each), developed by NPO Saturn or FGUP MMPP Salyut. New engine will be advanced version of AL-41F engine.
