I think you mean Su-57/F-35 acquisition depends on how Amca program shapes up since Tejas mk2 can’t fill the shoes of a stealth platform.
We should name Mk 2 as Mirage..
Whenever we believe it's time for first flight, date moves to next year/fiscal/quater..
The IAF top brass thinks Mk2 is already 'operationally irrelevant'. If the F414 deal stalls, Mk2 is DoA, anyway. Re-engineering the airframe for AL-31/41 will take a minimum of 5 years.
This will impact the AMCA mk1 program too for which mk2 serves as a testbed.
Defence secretary spoke about having a network centric air force to bridge the gap with Chinese 5th generation aircrafts.
The M88 T-REX, with a slightly larger fan diameter, would be a suitable replacement for the F414 and would not require any modifications to the aircraft, as its overall dimensions and weight would be lower than those of the F414. M88s with the correctly sized fan could be delivered quickly, as this would be the same size as the M88 prototype that had been considered for the UAE during the initial negotiations; the T-Rex would arrive three years later and would be fully interchangeable, providing the Tejas Mk2 with its final performance specifications, whilst the weapons system would have been developed using the enlarged M88.
