3.7" QF Anti Aircraft Gun Mk I

The British 3.7" QF anti aircraft gun was Britain's primary Heavy AA gun used during WWII. The gun had a bore of 3.7" or 94mm and fired a 25 lb shell (11kg) with a ceiling of 28,000ft (8,500m). This was later improved. Prior to 1938 Britain had fewer than 180 AA guns larger than 50mm. By the Battle of Britain in 1940 this number had risen to 1,140. The 3.7" QF remained in production until 1945. Heavy Anti Aircraft Regiments usually had three batteries each with 8 guns in two troops.
