traverse=The BL 10 inch guns Mks I, II, III, IV were British 32-calibres naval and coast defence guns in service from 1885.History
The British 10 inch calibre originated with the Committee on Ordnance in 1879 when it ordered a new 10.4 inch gun together with the new 9.2 inch [Hogg & Thurston 1972, page 176] as part of its transition from muzzle-loading to breech-loading guns. The proposed 10.4 inch gun eventually went into service in 1885 as a 10-inch gun firing a 500-pound projectile.
After Mk IV of 1889 the 10-inch calibre was discontinued in favour of 9.2-inch and 12-inch.
