I wonder if someday some one will invent an intake thats DSI but can deal with air speeds up to mach 3? Would you even need stealth coatings at such speeds?

Whats the current LRIP cost of a F-35?
How would it compare to a EF or squall in price?
India will need a type for its new carrier also.
They have a hot mess of aircraft types ATM.
Tejas, SU-30, Rafael, mirage, mig 29, and soon the T-50. It would be nice by 2030 to have a simple high med low air craft mix. Id reccomend
T-50 high, F-35 med and tejas low. Phase out the Su-30 in favor of the T-50.

deflecting / ctrl -ing air flw is just another way of saying ‘increase dra

g’ on one side,
its not what you would rationally do in straight flight.

underestimated ? on contrary it was overestimated,
as was proved when just about every last KPP threshold had to be reduced to make it pass

LoL so other aircraft go 50 degrees AoA with 0 deflection?

Your totally discounting body lift.
Your totally misjudging the plane on outdated assumptions.
For instance, before max AOA was demonstrated, many thought impossible for the F-35 to do + 50 degrees high alpha. It wasn’t until we saw the plane in action that we realized the insane deflection of the rear control surfaces.
This plane is greatly under estimated.

Has there been any modern jet fighter since the 80s that achieved IOC with full
Up capabilities and zero restrictions?
Super Hornet? Su-30? Typhoon? F-22?
