India is all set to spend over 25 billion U.S. dollars to induct 250-odd fifth generation advanced stealth fighter aircraft, local newspaper The Times of India reported on Tuesday. The aircraft, on way to being co-developed with Russia, will be part of India's biggest-ever defense project; and the pact between New Delhi and Moscow will be inked when Russian President Dmitry Medvedev comes visiting in India in December, said the newspaper. "We are looking to induct 200 to 250 FGFA in phases from 2017 onwards," Indian Air Force chief Air Chief Marshal P.V. Naik was quoted as saying. Naik said the 30-ton FGFA will be a "swing-role fighter, with very advanced avionics, stealth to increase survivability, enhanced lethality, 360 degree situational awareness, smart weapons, data-links, high-end mission computers" and the like. The aircraft will have a potent mix of super-manoeuvrability and supersonic cruising ability, long-range strike and high- endurance air defense capabilities. The aircraft will be built to Indian Air Force's specifications, the report said.
