The Soviet Union and the United States reached their climax during the Cold War. Give permission. Meanwhile, Soviet Rao developed state-of-the-art anti-aircraft systems and radar systems, and a U-2 aircraft was shot down. The downed aircraft and pilots were widely promoted in the Soviet Union.
In the meantime, under the supervision of CI, two versions of A-12 and YF-12 prototypes were made in 1959. Among them, SR-71 manufactured by Lockheed Martin was selected.

Prototypes of several versions of the SR-71 were phased out at an earlier stage and the SR-71 was finalized. The aircraft was capable of moving at a speed of Mark 2.6. Although able to see on the radar, the Soviet Union was not able to successfully chase an official aircraft. Engineers at Lockheed Martin have designed the aircraft's aerodynamics and aviation systems in such a way that the aircraft can fly at low to high speeds without much damage to the body.

The unofficial regular reconnaissance missions in North Korea and the Soviet Union operated the SR-71 ... also known as the Black Bird because of the black finish and the fact that the aircraft's outer surface heated up to 500 degrees Celsius during the Mark 2.2 speed. The United States later retired the SR-71 in 1997 for aerial refueling, increasing maintenance costs per flight, and military satellite development. The SR-71 has played a pivotal role in the history of US aviation and spying. The Soviets repeatedly frustrated North Korean pilots with the SR-71. Air-to-air missiles could not chase the aircraft. Many prototypes of the SR-71 were built in the '70s to suit unmanned aerial vehicles, with future aircraft thought to be drone-operated.
