Historical Project 640 Project 640 had been the PRC's indigenous effort to develop ABM capability. The Academy of Anti-Ballistic Missile & Anti-Satellite was established from 1969 for the purpose of developing Project 640. The project was to involve at least three elements, including the necessary sensors and guidance/command system, the Fan Ji (FJ) missile interceptor, and the XianFeng missile-intercepting cannon. The FJ-1 had completed two successful flight tests during 1979, while the low-altitude interceptor FJ-2 completed some successful flight tests using scaled prototypes. A high altitude FJ-3 interceptor was also proposed. Despite the development of missiles, the programme was slowed down due to financial and political reasons. It was finally closed down during 1980 under a new leadership of Deng Xiaoping as it was seemingly deemed unnecessary after the 1972 Anti-Ballistic Missile Treaty between the Soviet Union and the United States and the closure of the US Safeguard ABM system.
