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; however, it is also open to air services between Saint Helena and Ascension.

History

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 airfield was built using a US task force. The work was done by 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. A U.S. Air Force tracking station (now administered by the

) 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 during the

. At one stage, Wideawake became the busiest airport in the world for the number of aircraft movements. 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. 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. The USAF relies upon contractors to maintain the airfield facilities and the satellite station. An update is underway, with a completion date in 2025.

The NASA Tracking Station at Devil's Ashpit and the Cable & Wireless Earth Station at Donkey Plain were built in the mid-1960s for space operations and communications, including the latter's use for transmitting "microwave borne data via the Early Bird Satellite back to the NASA facility at Andover, Maine".

The station comes under the overall jurisdiction of the Commander British Forces South Atlantic Islands, an officer of one-star rank. , the incumbent is Commodore Jonathan Lett. The RAF airfield on Ascension Island is run on a day-to-day basis by around 19 RAF personnel, headed by a wing commander.

Planes for emergency medical evacuation flights and the newly established monthly charter flight to Saint Helena Airport are not impacted given the size of aircraft used. Essential personnel and equipment are also exempt from the suspension. In February 2021, an RAF A400M aircraft delivered Covid-19 vaccines to the island. While A330s were unable to land at the airport until the repair reached a stage to permit the resumption of full flight operations, the United States military continued to maintain a weekly flight between the island and Patrick Space Force Base in Florida, only for the use of its personnel, while the MV ''Ascension'' supply ship regularly services US facilities.
