Bagram Airfield-BAF, also known as Bagram Air Base (IATA: OAI, ICAO: OAIX), is located 11 kilometres (6.8 mi) southeast of Charikar in the Parwan Province of Afghanistan. It is under the Afghan Ministry of Defense. Sitting on the site of the ancient Bagram at an elevation of 4,895 feet (1,492 m) above sea level, the air base has two concrete runways. The main one measures 11,819 by 151 feet (3,602 m × 46 m), capable of handling large military aircraft, including the Lockheed Martin C-5 Galaxy. The second runway measures 9,687 by 85 feet (2,953 m × 26 m). The air base also has at least three large hangars, a control tower, numerous support buildings, and various housing areas. There are also more than 13 hectares (32 acres) of ramp space and five aircraft dispersal areas, with over 110 revetments. Bagram Air Base was formerly the largest U.S. military base in Afghanistan, staffed by the 455th Air Expeditionary Wing of the U.S. Air Force, along with rotating units of the U.S. and coalition forces. It was expanded and modernized by the Americans. There is also a hospital with 50 beds, three operating theatres and a modern dental clinic. Kabul International Airport is located approximately 40 km (25 mi) south of Bagram, connected by two separate roads. On 15 August 2021, the entire base fell to Taliban rebel forces after the NATO-trained Afghan Army had surrendered. All prisoners at the Parwan Detention Facility were released. The International Committee of the Red Cross had revealed that since August 2009 it was informed about inmates of a second prison where detainees are held in isolation and without access to the International Red Cross that is usually guaranteed to all prisoners; the existence of a second prison was denied by U.S. authorities.
