RAAF

RAAF Base Richmond (IATA: XRH, ICAO: YSRI) is a Royal Australian Air Force (RAAF) military air base located within the City of Hawkesbury, approximately 50 kilometres (31 mi) northwest of the Sydney Central Business District in New South Wales, Australia. Situated between the towns of Windsor and Richmond, the base is the oldest base in New South Wales and the second oldest in Australia. The base is home to the transport headquarters RAAF Air Lift Group, and its major operational formations, Nos. 84 and 86 Wings. The main aircraft type operated at the base is the Lockheed C-130 Hercules. Richmond is a regular venue for air shows and had at times been mooted as a site for Sydney's proposed second international airport. Sited on a piece of land originally known as Ham Common, Richmond became an RAAF base in 1925. Its inaugural commander was Flight Lieutenant (later Squadron Leader) Frank Lukis, who also led the base's first flying unit, No. 3 Squadron. Many other squadrons were formed at Richmond in the ensuing years, as well as a separate Station Headquarters and No.
