EOI for components was issued by GTRE in Jan 2020. That's the last I heard abt it.
Edit: The EOI is for a 50kn class engine (presumably for Ghatak). Following the engine timelines, leads to timelines for testing Ghatak.
I also meant altogether different designs for Airforce and Navy. Not something like F35A/B/C.
Further, does that mean that IAF goes for High-Medium-Low mix?
All platforms are phased away at some point in time. F35s would be around for 3 decades or more. Airforces operate in mixes of generations. Cost optimisation, capital acquisition budgets can't be wished away.
