The QF 14 pounder Mk I & II was a 3-inch high-velocity naval gun used to equip battleships for defence against torpedo boats. It was produced for export by Elswick Ordnance Company (Mk I) and Vickers, Sons and Maxim (Mk II). In Royal Navy service they were modified to use the standard 12-pounder shell.
The gun equipped the Swiftsure-class pre-dreadnought battleship built in Britain for Chile and purchased by the UK in 1903 before completion.
In British service the guns fired the same 3-inch, 12.5 lb shell as QF 12-pounder guns.
