Absolutely. But when you have audit and budget constraints blowing cold air on your neck, you are bound to make a balance between platform and spare order...
This is a typical project management problem, there will be components which are not ready by the time dead line arrives. in LUH's case, ultimately user exploitation of the platform is what the goal should be. waiting for indigenous components will delay the user exploitation and subsequent feedback cycle.
preferably atleast 75-100 order should be given to start and sustain the subcomponent manufacturing. there is also the question of fulfilling the annual quota of indigenous capex spending.
AOI for 5 LUH already came from civilian sector. If a combined LSP order from IA, IAF, IN, CG, BSF happens, the number would easily be around 70 helicopters.
