The Mark 16 mounted in a twin Mark 19 mount became the standard medium antiaircraft gun for the newer cruisers and destroyers of the Royal Navy. The mount was relatively simple, being unpowered and lacking an integral ammunition hoist (ammunition was passed from a fixed hoist into the back of the mount.) Singly mounted Mark 16s were used only by the Royal Australian Navy.

By the end of the war, the Mark 16 was being supplied with VT shells with radar proximity fuses and with Shark antisubmarine shells.
