Cardington is a village and civil parish in the Borough of Bedford in Bedfordshire, England.

Part of the ancient hundred of Wixamtree, the settlement is best known in connection with the Cardington airship works founded by Short Brothers during World War I, which later became an RAF training station. However most of the former RAF station is actually in the parish of Eastcotts, as is the settlement of Shortstown, which was originally built by Short Brothers for its workers. The village of Cardington is located to the north east of Shortstown and the RAF station, and houses most of the population of the parish, which was 270 in 2005, making it one of the least populated parishes in Bedfordshire.

Cardington became one of the major British sites involved in the development of airships when Short Brothers bought land there to build airships for the Admiralty. They constructed a 700-foot-long (210 m) airship hangar (the No. 1 Shed) in 1915 to enable them to build two rigid airships, the R-31 and the R-32. Some 800 people worked there in 1917, most of them travelled daily from Bedford. Shorts also built a housing estate, opposite the site.

The airships site was nationalised in April 1919, becoming known as the Royal Airship Works.

In preparation for the R101 project the No 1 shed was extended between October 1924 and March 1926; its roof was raised by 35 feet and its length increased to 812 feet. The No. 2 shed (Southern shed), which had originally been located at RNAS Pulham, Norfolk, was dismantled in 1928 and re-erected at Cardington.

After the crash of the R101, in October 1930, all work stopped in Britain on airships. Cardington then became a storage station.

In 1936/1937 Cardington started building barrage balloons; and it became the No. 1 RAF Balloon Training Unit.

For both airships and barrage balloons, Cardington manufactured its own hydrogen, in the Gas Factory, using the steam reforming process. In 1948 the Gas Factory became 279 MU (Maintenance Unit), RAF Cardington; and then, in 1955, 217 MU. 217 MU, RAF Cardington, produced all the gases used by the Royal Air Force until its closure in April 2000; including gas cylinder filling and maintenance.

The two airship sheds ceased being part of the RAF Cardington site in the late 1940s and they were put to other uses. The fence was moved, so they were outside the main RAF Cardington site.

From 1970, No. 2 shed was used by the Fire Research Station for large-scale fire tests in sheltered conditions which could not be carried out at their site in Borehamwood, Herts. Such tests included work on sprinklers in high-rack storage, department stores and other locations, gas explosions (following the Ronan Point disaster of 1969), and reconstructions of notable fires including the Manchester Woolworth's fire of 1979. In 1972 the Fire Research Station was merged with the Building Research Station to form the Building Research Establishment (BRE) and in the 1980s onwards some of BRE's work in non-fire areas was done in the hangar until around 2001; this included multi-storey steel, concrete and wooden buildings which were constructed and then destructively tested within the huge space available. This shed was completely reclad for BRE in the 1990s by the Property Services Agency and its contractors and thus was looked after in comparison with the other shed.

The buildings tests were mentioned during the course of the BBC series The Conspiracy Files as evidence in the controversy surrounding the collapse of World Trade Center Building 7 on 11 September 2001.

A company called Airship Industries tried to revive the fortunes of the airship industry in the other shed in the 1980s, but the efforts ended in failure. The site is currently being used for the development of a new design of airship, the Skycat, by the company Hybrid Air Vehicles.
