The QF 3.7-inch AA gun was roughly the equivalent of the German Flak 8.8-cm and American 90-mm AA guns, but with a slightly larger calibre of 3.7 inches, approximately 94-mm. Production began in 1937 and it was used throughout the Second World War in all theatres except the Eastern Front. It remained in use after the war until AA guns were replaced by guided missiles beginning in 1957.The gun was produced in two versions, one mobile and another fixed. The fixed mounting allowed more powerful ammunition, Mk. VI, which gave vastly increased performance. Six variants of the two designs were introduced. (Wikipedia)
