Class A airfield
From Wikipedia, the free encyclopedia
Class A airfields were World War II military installations constructed to specifications laid down by the British Air Ministry Directorate-General of Works (AMDGW). Intended for use by heavy bombers and transports, they were the standard air base design for the Royal Air Force as well as U.S. Army Air Forces units operating from the UK.

Upon the entry of the US into the war a number of RAF Class A bases were transferred to the U.S. Eighth Air Force for use as heavy bomber bases with the RAF units formerly occupying them being redeployed to other RAF bomber airfields, and U.S. Army Engineer Units constructed more airfields to this standard or brought earlier airfields up to this specification by lengthening runways, etc.[1] Many units of the U.S. Ninth Air Force also flew from Class A airfields. The term Class 'A' came about because, quite often, the resultant aerial shot of the crossed runways would look like the letter A.[2]
