QF 6-inch naval gun
These guns were developed to exploit the new "QF" technology, which involved loading the propellant charge in a brass case with integrated primer in its base.The brass case sealed the breech, allowing a lighter mechanism, and at the same time disposed with the necessity of washing or sponging any smouldering fragments left from the previous shot, which could ignite the charge (then of black powder) prematurely.[3] The preceding generation of British 6-inch guns (BL Mks III, IV and VI) had old-style trunnions by which they were mounted on Vavasseur inclined slides to absorb recoil.The pre-dreadnought battleship classes of the Royal Sovereign-class (including the turreted HMS Hood-class, Centurion-class, Majestic-class and Canopus-class ships carried up to 12 guns.During the Second Boer War one gun was brought ashore fromHMS Terrible in Natal in February 1900 at the request of General Redvers Buller, presumably[citation needed] in response to the failure at Colenso.[7] The 7-ton weight (compared to the 2½ tons of the Boer 155 mm "Long Tom") meant that it was effectively immobile on the battlefield and could not be moved forward to shorten the range.[11] In World War I Britain urgently needed heavy artillery on the Western Front, and various obsolete 6-inch naval guns were converted to 8-inch howitzers.[14] These guns were adopted in very limited quantity by the United States Army Coast Artillery Corps as part of the Endicott period fortifications, and were initially mounted 1898–1907.
