HISTORICAL DATA
This was an automatic gun of “all-steel” construction with a high rate of fire and was the first British 6” (15.2 cm) design to use cartridges instead of bagged powder charges in over sixty years. These weapons were originally intended for triple mountings on the projected Neptune class and for twin mountings on the projected Minotaur class of 1947. These projects were both canceled shortly after the end of World War II and the first two experimental guns were not completed until 1949. Per the post-war naval gun designation system, they were then redesignated from QF Mark V to QF Mark N5.

In the early 1950s, these weapons were selected to arm the Tiger class cruisers, which had lain incomplete since the end of World War II. These ships were then completely redesigned and work was resumed in 1954 with HMS Tiger being completed in 1959, nearly two decades after she had first been laid down.

There are many reports that these weapons were unreliable in service, but that does not seem to have always been the case. The initial problems found during development at Shoeburyness and with the prototype on HMS Cumberland were rectified during trials, one major breakthrough being the choice and filtration of the oil in the oily servos fitted to the turrets.

These weapons were controlled by the Gun Direction System (GDS1) using the Type 992 radar. This system enabled the ships to engage multiple targets within a few seconds of each other and was technically very advanced for its time.

HMS Blake was the last cruiser in commission in the Royal Navy. In December 1979, a few days before she was decommissioned, she enjoyed the distinction of firing the Royal Navy’s last 6” (15.2 cm) gun salvo.

Constructed of a loose barrel with hydraulically operated horizontal sliding breech block.
