I seriously doubt whether Washington will release mini turbofan engines to us.Then we must go for American options for engine alone.. May be we can contact to get the engine used in tomohawks, for time being.
Any info on their willingness?. Can you quote a source?. The Americans may offer the Tomahawk missiles (probably) for use against the Chinese but not the engines themselves a la carte. They would like us to be dependent on them. Not be self-sufficient.
