During World War II, these guns were used in emergency coastal batteries.
This gun has the distinction of having the highest muzzle velocity of any British 6" (15.2 cm) used without super charges.
Similar to other Vickers wire guns with cannelured rings except that the wire was used only part way, with the B tube directly over the A tube forward of the jacket. The reserve guns, which never went to sea, differed in having a tapered inner A tube. Used a hand-worked Welin breech-block. A total of 19 guns were produced.

|Note: The Rate of Fire
figure given above is found in references for British guns of this caliber,
but "Warrior to Dreadnought: Warship Development 1860-1905" quotes
Jellicoe's 1906 figures for rates of fire for these guns in gunlayers'
tests and in battle practice and notes that the latter figures corresponded
well to those actually attained by the Japanese at Tsushima:
Gunlayers Test: 12 rounds per minute
In "Jutland: An Analysis of the Fighting" by John Campbell, it is stated that almost all British capital ships had few or slow hoists for their 6" (15.2 cm) guns and that once the ready ammunition was used up, the rate of fire dropped to about 3 rounds per minute.
