Mig-25 was a role model for F-15 among other things.
I have no love for the Soviet Union and quite contrary but facts are facts.
Good gosh, the MIG-25 was no “role model” for the F-15. About the only commonality between those two platforms is the twin tail.
Those two aircraft had two completely different missions-the MIG-25 was an interceptor, and the program resulting in the F-15 was prompted by the MIG-25, but not because of the plane itself but because the US erroneously thought it was an air superiority fighter, which it was not.
The gross weight of the MIG-25 was 20,000 lbs greater than the F-15. Those aircraft aren’t in the same universe when it comes to size, performance, range or mission (Speaking of the F-15A)
Facts are indeed facts. Those last two paragraphs are indisputable facts.
