We have already signed a deal for customized FE414S6-IN (tailor made for Indian climate) engine. This will go in Tejas Mk2.
Ofcourse it is common knowledge that LCA Mk-II will have customized F414.
But what I was saying was w.r.t AMCA. Considering the fact that AMCA is designed as a twin-engine swingrole fighter (with supercruising as a desirable trait, although it has not been revealed what exactly IAF expects from AMCA, or if it expects anything at all!), we now have 4 possible, practical paths that we can take :
1) Keep it in line with LCA developments. This means a further modified/uprated (if deemed necessary) version of the F414 that's going on LCA Mk-II.
2) Keep it in line with our other fifth-generation gamble : FGFA. Conduct a feasibility study for a downscaled (w.r.t thrust-levels, weight & size. Not tech) version of the Izdeliye-30 turbofan which is a truly next-gen engine with Variable-Cycle technology, Plasma-arc ignition (doesn't need oxygen to start), among other NG technologies.
3) Go for customized variants of Snecma M88, ensures familiarity with Rafale Make-in-India program.
4) Make a stupid decision & go for Eurojet EJ200 or EJ220/230 versions.
R&D regarding indigenous K10+ and K11 Kaveri turbofans should continue, but should't be put on AMCA for operational purposes until fully matured. Let the companies learn all that they can from the F414, M88, uprated AL-31 and Izdeliye-30 licensed productions.
So if we are going to phase out older planes then it will be MiG 29 first and Sukhoi 30MKI next, in that order, I guess? The kind of investment we have made in SU30MKI doesn't make it seem like they are going away for 20 more years. So the mix will be MiG 21 bison, Tejas, Mirage 2000, Jaguar, Rafale, MiG 29, SU30, AMCA, FGFA
At the very least you can be sure MiG-21 and Jaguar won't be in service by the time AMCA starts getting inducted into operational squadrons. By the time AMCA gains numbers, MiG-29 will be on it's way out followed by Mirage-2000.
I expect Su-30MKI to be starting the phase-out process in mid to late 2030s. The earliest-builds from 2002-2004 will go out first. Replaced by more FGFAs.
IAF is like an obsessed school kid who wants to collect all latest models of hot wheels toys. I think we aren't giving enough attention to our strategic airlift capability. The medium lift transport aircraft project with Russia has hit a roadblock, no new C17's are coming and we purchased CASA C295 even when efforts are being made to revive the HAL-Russia project. Someone is seriously trying to fill up all aircraft requirement with imports to prevent indigenous development.
If Indo-Russian MTA is cancelled, then that could mean either 40+ C-130Js (possibly produced by Tata under MII just like C295), or ~25 Airbus A400Ms. But my money is on additional C-130Js. The advantage here is that if Tata gets to make them in India, we can also turn TASL centers into the regional Asia/Middle-East MRO center for all C-130, C-130J and C-130J-30 planes in this neighbourhood.
Plus the chances for procuring something like KC-130 will go up. Cool bird if you want to refuel choppers mid-air.
