RAF Spitalgate

Military conversion and strategic rationalisation. The airfield was closed to flying as part of the post-war reduction of the UK's military estate and was repurposed for use by the British Army, which did not require an active runway.

The site was renamed Prince William of Gloucester Barracks in 1976 and is an active British Army installation. It is home to the Army Training Regiment (Grantham), which conducts basic training for new recruits. A large portion of the former airfield, including the runways and domestic sites, has been sold for a major housing development known as 'Spitalgate Heath'. While the runways are gone, several original WWI-era hangars and other military buildings remain and are still in use by the Army.

RAF Spitalgate has a long and significant history in British military aviation. It opened in 1915 as Royal Flying Corps Station Grantham and served as a major training depot during World War I, training over 2,500 pilots. Between the wars, it was home to No. 3 Flying Training School. During World War II, its role expanded significantly. It was the headquarters for No. 5 Group, RAF Bomber Command from 1937 until 1943, playing a crucial role in the strategic bombing campaign. It also served as a satellite airfield for fighter squadrons, including several Polish units flying Hurricanes and Spitfires. A landmark event occurred in 1941 when the first operational flight of the Avro Lancaster, Britain's most famous heavy bomber, took place from this airfield. After the war, it continued to serve as a training base for various RAF units until its closure to flying.

None. The site is extensively redeveloped with an active Army barracks and a large, ongoing housing estate built directly over the former runways and airfield grounds. Reopening as an aviation facility is unfeasible due to the permanent nature of this redevelopment.
