Yeah they are still deciding.They are currently deciding on which private company will be involved in the R&D phase.
K9/ K10 is still an imagination. Seems like they themselves don't know what they want. Kaveri failed to generate 100kN within weight limitation, it's heavy, why do they think that kaveri tech specification will be implemented in new engine. They want to ruin the JV I guess. I don't think any one will be ready using Kaveri as base, its a small engine, good thrust for that size but heavy one.Kaveri can't power AMCA the way it is today. A new engine program is planned. F414 will be the interim engine.
But India still doesnt have that indigenous manufactured, that's the problem it's a foreign tech. The Mig 29 and Su30s were fitted later on.The F-35's EODAS is outdated. The Litening G4 alone is two generations ahead of the EODAS
It will be better if India also produces such system.
