the superior range of the 10.5 cm (4.1-in) SK L/45 guns of German torpedo boats, Viking was experimentally rearmed, replacing the forward 4-inch gun with a BL 6-inch Mk VII (alongside HMS Swift, she was one of only two Royal Navy destroyers ever to carry such a weapon). The 6-inch gun proved too large for the Tribal class, and other ships did not receive this modification. On Viking, it was replaced in late 1916 by a QF 4-inch Mk V gun.
