What did the declassified documents reveal?

Wu‑kung Airfield, China – a Central Intelligence Agency photographic‑interpretation report dated August 1971, detailing the airfield’s role in strategic‑weapons industrial activity. The report was declassified and approved for release on February twenty‑third, two thousand four, under the authority of the CIA’s Director of Central Intelligence. It was made publicly available through a Freedom of Information Act request and posted on The Black Vault, where the full text can be accessed at the archive link. The document begins with an abstract. It states: “Wu‑kung Airfield is one of the principal medium bomber bases in China. Its current inventory includes BADGER, designation TU‑16, and BULL, designation TU‑4 aircraft. The airfield was complete and operational when it was first seen on overhead photography. It has a single east‑west runway.” The report continues: “Wu‑kung Aircraft Repair Base is collocated with Wu‑kung Airfield. It contains approximately— and probably serves as a major repair base primarily for bomber aircraft.” The narrative proceeds to describe the location, noting that the airfield lies approximately eight and a half nautical miles east‑southeast of the town of Wu‑kung, and about fifty‑five nautical miles southwest of the Hsi‑an Airframe Plant Yen‑Liang 172, the series‑production plant for BADGER medium jet bombers. The record observes that BADGER and BULL aircraft were based at Wu‑kung as of the latest photography, and that a small number of BEAGLE, designation IL‑28, have also been observed, suggesting that type may be serviced at the site. Construction activity is detailed: runway lengthening and apron enlargement were first observed complete in the early‑seventies, and the aircraft‑repair base was observed under construction and later completed. The report notes that Wu‑kung Airfield was the first Chinese airfield to receive BADGER bombers. Until nineteen sixty‑eight, China was known to have only two BADGER aircraft, supplied by the Soviet Union in nineteen sixty. The first Chinese BADGER were observed at Wu‑kung and at Hsi‑an Airframe Plant Yen‑Liang 172. The number of BADGER observed at Wu‑kung increased over time, while the number of BULL aircraft decreased. The highest BADGER count recorded was twenty‑six on a specific photograph. The repair base, situated immediately south of the airfield and linked by a taxiway, supports activities ranging from engine test and overhaul to complete aircraft maintenance and modification programs. The airfield and repair base are served by an all‑weather road network and a rail spur from the Hsi‑an to Wu‑kung railroad. Electric power is supplied from a local source via a small transformer yard on the southern boundary of the repair base. A steam plant, item thirty‑two, is located at the repair base, with two additional small steam plants in the aircraft‑maintenance areas at the airfield. Two housing and support areas lie directly south of the repair base, likely serving both the base and…
