HMAS Brisbane [II] (1966) was the second vessel of that name to serve in the Royal Australian Navy. She was the third of the RAN's American-built "Charles F. Adams" class guided-missiles destroyers. (The other two were HMAS Hobart and HMAS Perth.) These ships cost $40 million each (or $50 million with missiles) and were the first major Australian warships designed and built in America. They carried a complement of 20 officers and 312 sailors. Apart from the 5-inch/54 calibre guns, they were armed with Ikara missile systems and anti-submarine torpedoes.

During the Gulf War (1990-91), Brisbane was one of four Australian warships to serve a tour in Gulf waters. These formed part of the anti-aircraft screen for the US Navy carrier battle groups. Brisbane arrived in the Gulf in December 1990 and served there until March 1991, performing a number of roles. Apart from contributing to the anti-air defences in the carrier screen, she also kept watch for mines and ensured that small civilian craft kept well away from the carrier group. Later, during Desert Storm, Brisbane controlled fighter combat air patrols and tanker aircraft. Her final role was as an escort for US replenishment ships.

Mount 52
This gun mount was the aft mount (Mount 52) on the ship. The ammunition feed system for the single 5-inch gun was almost entirely automated and this meant that it could achieve a continuous firing rate equal to what an expert crew could manage over short bursts using two gun mounts. The starboard "bubble"dome, or "frog-eye", has been removed. This dome was normally used for anti-aircraft fire control within the mount (the retained port dome being used for local surface control), but this was not needed here because of the use of the Tartar anti-aircraft missile system on these Australian ships.
