The QF 6 pounder Nordenfelt was a light 57 mm naval gun and coast defence gun of the late 19th century used by many countries.
Note that this gun should not be confused with the short-barreled 57 mm Cockerill-Nordenfelt "Canon de caponnière" or fortification gun, which was used to arm the German A7V tank in World War I.
Nordenfelt guns can be visually differentiated from equivalent and similar Hotchkiss guns by having slimmer barrels than the Hotchkiss, hence the Nordenfelt was considerably lighter.
United Kingdom[]
The UK adopted a 42-calibre version as Ordnance QF 6-pounder Nordenfelt [note 1] Mk I, Mk II, Mk III.

They were originally mounted from 1885 onwards for use against the new (steam-driven) torpedo boats which started to enter service in the late 1870s. The Nordenfelt gun was adopted at the same time as the very similar QF 6 pounder Hotchkiss, but the Navy was not satisfied with the special Nordenfelt ammunition and fuzes. Following the explosion in 1900 of an ammunition ship due to defective fuses, Britain replaced Nordenfelt fuzes with the Hotchkiss design. Nordenfelt guns were phased out in favour of the Hotchkiss and were declared obsolete by 1919.[3]
Finland[]
When Finland gained its independence from Russia in 1917 dozens of QF 6-pounder Nordenfelt cannons were stationed in Finland. After the Finnish Civil War in 1918 around 35 - 40 Nordenfelt cannons became available to the Finnish army. These guns were later used as a standard light coastal gun of the Finnish coastal artillery and were in service until the 1950s. During World War II some of these guns were also used as fortification artillery and bunker guns in the Mannerheim Line.[4]

The Victorian Navy manual of 1895 quotes a muzzle velocity of 1,818 ft/s (554 m/s) using a 1 lb 15 oz (0.88 kg) gunpowder charge, but maximum range of only 5,000 yards (4,600 m). Text Book of Gunnery 1902, Page 337 quotes m.v. of 1,818 ft/s (554 m/s) and maximum range 4,500 yards (4,100 m). 5600 metres is quoted for the 48 calibres model at Krepost Sveaborg, Helsinki.
