Nothing personal, and I get the distinct impression you carry a torch for the Soviet Union, but...the MIG-25 was a waste of money and a joke.
And anything the Soviets did with satellites didn’t help the citizens of that country one bit...
You seem to miss my point-it isn’t the American scientists that produced things that outperformed Soviet products-they themselves aren’t exceptional-American Exceptionalism is the combination of the Scientists with our Republic.
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.
