The QF 14-pounder was a 3-inch medium-velocity naval gun used to equip warships for defence against torpedo boats.

The gun equipped ships built in Britain for various foreign navies including Chile.

In 1900 they were removed, mounted on field carriages and went to China with the Victorian Naval Contingent to confront the Boxer Rebellion.

These 2 guns were non-standard and fired QF fixed rounds (i.e. the cartridge was loaded with shell attached) unlike the standard guns which fired separate ammunition (i.e. shell and cartridge loaded as separate items).

[3] In Victorian naval service in the 1890s the gun is reported as firing a shell weighing 14 lbs to a range of 8,000 yards with a muzzle velocity of 2100 ft/second, using a 6.5 lb black powder charge.
