SR-71 was a spy plane, not a fighter....it didn't carry any weapons...the Skunk Project ended and all SR-71s retired and spy planes were no longer needed as Satellite Technology became advanced
Still a war time aircraft, Cold War time aircraft, isn't it? It's the coolest looking one too, in my opinion, and it's still the fastest manned airbreathing jet aircraft ever made.
"the SR-71 operated at high speeds and altitudes to allow it to outrace threats. If a surface-to-air missile launch were detected, the standard evasive action was simply to accelerate and outfly the missile."
"At sustained speeds of more than Mach 3.2, the plane was faster than the Soviet Union's fastest interceptor, the Mikoyan-Gurevich MiG-25, which also could not reach the SR-71's altitude. During its service life, no SR-71 was shot down."
