I found this info initially
F-14 F-15 on the f-14 specs note that the F-14/a engines produce 20,900 lbs of thrust. Later models produce 27,000lbs of thrust each.
lower on the spec sheet it states max speed as mach 1.88, Im guessing this wasnt revised after the engine upgrade.
The F-15 does indeed have a mach 2.5+ top speed at "sea level" I wonder how fast at highr alts
Its engines produce 25,00;bs of thrust each. Soo Im figuring they are fairly evenly matched on top speed when you figure in wheight of the A/C and thrust to wheight ratio,s..
Other fact sheets I have read give slightly different numbers and some just dont jive {like having the same speed with lesser engines}
I suppose this is the "classified barrier"
