The Ordnance QF 6 pounder 6 cwt Hotchkiss Mk 1 and Mk 2 was a shortened version of the original QF 6 pounder Hotchkiss, and was developed specifically for use in the sponsons of the later Marks of British tanks in World War I, from Mark IV onwards.

The original 6 pounder had turned out to be too long for use with the current British heavy tank designs, which mounted guns in sponsons rather than turrets. The 6 pounder 6 cwt Mk I of single tube construction was introduced in January 1917 in the Mark IV tank. The Mk II gun was developed at the same time, having a built-up barrel construction.[1]
