QF 3.7-inch AA gun

In 1925 the RAF established a new command, Air Defence of Great Britain, and the Royal Artillery's anti-aircraft units were placed under its command.

•

In British service the gun replaced the 3 inch AA gun in Heavy Anti-Aircraft (HAA) Batteries of the Royal Artillery, almost always in Heavy Anti Aircraft Regiments, which were usually in an Anti-Aircraft Brigade.

•

It remained in use after the war until AA guns were replaced by guided missiles, notably the English Electric Thunderbird, in the late 1950s.

QF 3-pounder Hotchkiss

A 3-pounder Hotchkiss was used on an improvised mounting in a battle that resulted in Australia's first prisoners of World War 2 being captured in 1940 near Berbera.
