Mk I Churchill tank with hull-mounted 3-inch howitzer on exercises on Salisbury Plain, January 1942

Ordnance QF 3 inch howitzer was a howitzer fitted to British tanks of the Second World War so they could fire a HE shell in "close support" of infantry.

It was used to equip the British Infantry tanks: Matilda II, Churchill tank Mk I, and the cruiser tank Crusader (65 rounds).

Later in the war a larger 95 mm howitzer was employed for the same purpose.
