Cold War: Soviet Air Defence Forces pilot Viktor Belenko lands a Mikoyan-Gurevich MiG-25 jet fighter at Hakodate in Japan and requests political asylum in the United States; his request is granted.

The Cold War was a period of global geopolitical rivalry between the United States (US) and the Soviet Union (USSR) and their respective allies, the capitalist Western Bloc and communist Eastern Bloc, which began in the aftermath of the Second World War and ended with the dissolution of the Soviet Union in 1991. The term cold war is used because there was no direct fighting between the two superpowers, though each supported opposing sides in regional conflicts known as proxy wars. In addition to the struggle for ideological and economic influence and an arms race in both conventional and nuclear weapons, the Cold War was expressed through technological rivalries such as the Space Race, espionage, propaganda campaigns, embargoes, and sports diplomacy.

The Soviet Air Defence Forces was the air defence branch of the Soviet Armed Forces.

Viktor Ivanovich Belenko was a Soviet-born American aerospace engineer and pilot who defected in 1976 to the West while flying his MiG-25 "Foxbat" jet interceptor and landed in Hakodate, Japan. George H. W. Bush, the Director of Central Intelligence at the time, called the opportunity to examine the plane up close an "intelligence bonanza" for the West. Belenko later became a U.S. aerospace engineer.

The Mikoyan-Gurevich MiG-25 is a supersonic interceptor and reconnaissance aircraft that is among the fastest military aircraft to enter service. Designed by the Soviet Union's Mikoyan-Gurevich bureau, it is an aircraft built primarily using stainless steel. It was to be the last aircraft designed by Mikhail Gurevich, before his retirement.
