ChangKong-1
From Biocrawler, the free encyclopedia.
The ChangKong-1 (CK-1) is a radio-controlled target drone developed by the Nanjing Institute of Aeronautics in the People's Republic of China. It is based on the reverse engineering of Lavochkin La-17C drones supplied to the PRC by the Soviet Union in the early 1960s before all such Soviet technical aid to the nation was withdrawn. Its chief designed was General Zhao Xu and the first example flew on December 6 1966. A key difference from its predecessor is the use of a turbojet in place of a ramjet engine.
Entering service with the People's Liberation Army Air Force (PLAAF) in the late 1970s, its main mission as a target drone was soon supplemented by an additional role in collecting air samples from Chinese nuclear tests, replacing crewed aircraft in this role.
