Senior IAF officials have told ET that several questions have been raised by India on the FGFA program, with little feedback or sharing of details by the Russian side. For starters, the IAF has not been given a tentative per unit production cost of the next generation fighter that is being developed by Sukhoi. "It is impossible to sign on to anything with Russia till we have some clarity on the per unit cost of an aircraft. If the price turns out to be exorbitant, we may not even be able to afford it," a senior officer told ET.
The air force's worry is not without merit, given that production costs for Russian aircraft in India have gone up tremendously in the past 10 years. At present, a Sukhoi 30 MKI that would cost Rs 227 crores to manufacture in Russia, rolls out of HAL's Nashik plant for over Rs 440 crores.
This considerable mark-up is due to the extra man hours that are required by HAL to manufacture an aircraft, the official explained.
Even if price could be sorted out, officials say that several basic questions on technical capabilities of the under development fighter exist with no reasonable explanation from Russia in sight. Besides the fact that Russia has not been able to develop a new engine for the aircraft that would give it super cruise capability - to fly faster than the speed of sound without going to afterburners - the IAF is worried about the weapons package for the fighter.
"Till now, all we see is that the weapons being offered by Russia for the FGFA are the same ones that are available for our Su 30 MKI fleet. A fifth generation aircraft is not just the platform but the entire package - from sensors to weapons, which we are yet to see," the officer said.
The IAF feels that as per the present design, the weapons on offer are too large to be fitted into the internal weapons bay of the FGFA. At present configuration this would end up with the weapons being loaded externally, taking away the most basic feature of a fifth generation fighter - stealth. "The weapons bay is too small and external weapons would show up the fighter on radar," the official told ET. India has already invest $ 295 million in the Russian FGFA program with a design contract signed in 2010. However, a subsequent plan for a full fledged research and design program has not materialized, even as the intended Indian work share on the platform has depleted.
While the US has two fifth generation fighters operational - the F 22 and F 35, China is fast tracking its own next generation fighter programs -the J 20 air superiority fighter and the FC 31 medium fighter. India has also announced its plans for a future Advanced Medium Combat Aircraft (AMCA) with the air force looking at a 15 year induction plan if the project progresses on time.
