By November 1941 it was placed into "care and maintenance" as there was no use for it by then, as the Battle of Britain had ended and there were sufficient airfields in the area to continue the war without it.

RAF Units stationed at Chilbolton: America came into the war after the bombing of Pearl Harbor by the Japanese in late 1941, and the Allies began preparations for the invasion of Europe.

Chilbolton continued to be retained by the USAAF for use by transports as a staging airfield for cargo operations to and from the Continent and it was not returned to the RAF until March 1945, by which time most of the C-47 groups had been transferred to forward stations in France.

Folland Aircraft also occupied another part of the airfield to conduct similar work on their products, chiefly the Midge and Gnat, but were gone by the end of 1961.

With their departure, the wartime airfield began to be dismantled, with large sections of runway, perimeter track and loop hardstands being removed for hardcore.

Flying continued on the old airfield during the 1980s when helicopters and light aircraft serving a field-spraying organisation were in residence, using a grass strip built parallel to the main north–south 12/30 runway.

Today, the perimeter track has been largely reduced to a single-lane farm road as much of the airfield has been returned to agricultural use.

In aerial photography, however, much of the former wartime airfield's runways and hardstands can be seen as disturbances on the landscape, giving a ghostly appearance to the area.

A large Type B.1 hangar also survives in agricultural use on the Leckford Estate which occupies the SW corner of the former airfield.
