RAF Mousehold Heath was a Royal Air Force station on Mousehold Heath near Norwich. The area between the Salhouse and Plumstead roads (outside of the outer ring road) was originally the Cavalry Training Ground. It became the Royal Flying Corps Mousehold Heath aerodrome during the First World War and was the location where Boulton & Paul, among other local manufacturers, passed over the aircraft they had built into the hands of the RFC. It was sometimes also known as Norwich aerodrome by the RFC On the formation of the RAF in April 1918, it became "Royal Air Force Mousehold Heath".

After the war, Boulton and Paul continued to use the site. The Norwich & Norfolk Aero Club was formed at the airfield in 1927 which then became the first Norwich Airport in 1933. The airfield fell into disuse during the Second World War and has now mostly been redeveloped for housing.

Boulton & Paul was a Norwich general construction firm working in metal and wood. In 1915 they approached the government offering their services for production of war materiel. They gained a trial contract for 25 Royal Aircraft Factory FE.2b At the time, an Aircraft Acceptance Park for aircraft being produced in Norfolk was under construction by the War Department near Thetford about 25 miles away. Rather than deliver aircraft there, Boulton & Paul suggested putting an aerodrome on the Cavalry Drill Ground to the north of Norwich. This was accepted and Boulton & Paul gained a contract for the buildings to house an RFC School of Flying on the new aerodrome; No. 9 Reserve Aeroplane Squadron was formed there in July 1915. In October 1915, the first aircraft built by Boulton & Paul, a FE2b serial 5201 and marked "Bombay No.1" flew from Mousehold.

As aircraft output increased the aerodrome was extended, with more buildings built by Boulton & Paul. In 1917, the RFC established Norwich Aircraft Acceptance Park, later named No. 3 (Norwich) Aircraft Acceptance Park at Mousehold to take aircraft from other local manufacturers as well, this included Portholme Aircraft Company, Mann Egerton and Ransomes, Sims & Jefferies. Ransomes based in Ipswich had their aircraft works built by BP and been given BP's jigs and templates for FE2 construction when BP moved to building the Sopwith Camel.

In 26 July 1919 the acceptance park became the Norwich Storage Park.
