The F-119 engined F-22 has fixed inlets and is not especially fast. What makes you think fixed inlets make a difference? The engine, therefore, does _not_ have to be made of the *very* expensive highest-temperature alloys. The F119 is made of MUCH better alloys than the J93. I think the temperature problem is handled by the fact that the J93 compresses the air much less than an F119. So does the J58 and the engine the Mig-25 uses. My question is, how long would the F-119 last in a mach3 aircraft like the B-70?
