QF 14 pounder naval gun Mk I & II naval gun

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.

Service

British ammunition
In British service the guns fired the same 3-inch, 12.5 lb shell as QF 12-pounder guns.
