Founded in 1957, Changfeng is one of the design academies under the China Aerospace Science and Technology Corporation (CASIC), and is China’s main designer and producer of air and space defense systems.  With a growing emphasis on air and space defense, it consists of a design department, 10 specialized research institutes, a simulation center, three factories, and nine independent commercial enterprises. It is located on Yongding Road, in the western suburbs of Beijing. The research institutes and manufacturing facilities of the Second Academy are clustered in a complex in western Beijing, along with other specialized guidance, navigation, and control R&D centers of the CASIC and CASC (China Aerospace Science and Technology Corporation) academies. 
Changfeng conducts research and development, and production of air and missile defense, anti-satellite weapons (ASAT), radar systems, and associated ground equipment. The People's Liberation Army (PLA) Air Force serves as a core customer the Second Academy, for which Changfeng has produced several surface-to-air (SAM) systems, including the Hong Qi (HQ)-2, HQ-7, and HQ-61.  Changfeng developed the 8610 SRBM (Short-Range-Ballistic-Missile) based on the HQ-2 SAM previously developed by the academy. It is likely that the 8610 and associated technologies were sold to Iran. 
In recent years, Changfeng has expanded its focus to include submarine-launched and land-based ballistic missiles, such as the Julang (JL)-1, Dong Feng (DF)-1, and DF-21. The DF-21D, sometimes known as a “carrier killer,” is thought to be the only missile capable of sinking an aircraft carrier.  It is also likely that the Second Academy designed, developed, and produced the space intercept systems that were tested in January of 2007 and 2010.
