The Kh-22 family was developed in the USSR in the 1960s and specifically designed to be launched from Tupolev-22 bombers.
Later, both the missiles and the aircraft were modernized as part of the so-called "Kh-22 special air-to-surface missile complex."
Upgraded in the 1970s, the missile had an impressive speed of 4,000 kilometers per hour, a 1,000-kilogram warhead and a range of 500 kilometers.
