RAF Ascension Island (IATA: ASI, ICAO: FHAW), also known as Wideawake Airfield or Ascension Island Auxiliary Field, is a military airfield and facility located on Ascension Island in the Atlantic Ocean. The airfield is jointly operated by the Royal Air Force (RAF) and the United States Space Force (USSF). Under the terms of an international agreement between the UK and US governments, only state aircraft (e.g. military and diplomatic flights) are authorised to land at Ascension, with the sole exception being civil aviation between Ascension and Saint Helena. The facility is home to a U.S. Space Force ground tracking station in support of the Eastern Range and rocket launches from Cape Canaveral Space Force Station in Florida.

In 1939 Ascension became important as a high-frequency direction finding radio station covering trade routes. Wideawake Airfield (named after a noisy colony of sooty terns nearby) was built by the US military in 1942 by arrangement with the British government. The work was done by a US task force of the USAAF 38th Engineer Combat Regiment and the airfield opened on 10 July 1942. The first aircraft to land on Ascension Island was a Fairey Swordfish from HMS Archer in June, 1942 and it went on to be used by more than 25,000 aircraft as a staging point during the Second World War. An unusual visitor was a captured German Junkers Ju 88 bomber, which landed there in October 1943 as it was being flown from the Middle East to the United States in stages. A U.S. Air Force tracking station (now administered by the U.S. Space Force) was officially activated as a satellite of Patrick Air Force Base (now Patrick Space Force Base) in Florida on 25 June 1956. The airfield's runway was extended in the latter part of 1980. The base was re-garrisoned by the RAF in 1982 and used extensively as a staging airfield, for the Avro Vulcan bombers and the Handley Page Victor tankers, during the Falklands War. A series of long-range bombing raids was carried out from there under the name Operation Black Buck. The first mission was on 30 April 1982. At one stage during that conflict, Wideawake became the busiest airport in the world for the number of aircraft movements. In 2017 a parliamentary answer disclosed the runway needed a 'full depth resurfacing'. In June 2020 the U.S. Department of Defense announced the runway would be repaired, with a completion date in 2022 after eighteen months work; until then commercial flights were suspended. Normal flights were able to resume in August/September 2022 when repairs to the eastern side of the runway were completed (see further discussion below). The USAF relies upon contractors to maintain the airfield facilities and the satellite station. An update is underway, with a completion date in 2025.
