HMAS Nizam (tactical numbers: G38 and D15) was an Australian, or rather British destroyer, the keel of which was laid in July 1939, launched in July 1940, and commissioned in December 1940. The total length of the ship at the time of launching was 108.7 m, width 10.9 m, with a standard displacement of approximately 1,800 tons. In turn, the maximum speed was up to 36 knots. The ship's armament included: 3 twin 120mm Mark XII guns, a single 102mm AA gun, and 4 20mm Oerlikon AA guns.
HMAS Nizam was created as one of the N-class destroyers, which, along with very similar J and K classes, was developed for the British Royal Navy as a continuation of the Tribal type, with reduced size, construction costs and overall construction complexity. They also introduced a system of two boiler rooms, which was a peculiar novelty in British destroyers. The J, K and N class ships turned out to be successful, showed good seagoing performance, considerable modernization potential and high combat value. HMAS Nizam, although it was built for the Australian fleet and formally remained its property, served in the British Royal Navy throughout World War II. Shortly after entering service, in 1941, HMAS Nizam was directed to the Mediterranean Sea, where it participated in operations in the Crete area, and in the period 1941-1942 it participated in the protection of convoys heading to Malta. In the years 1942-1943 it operated in the Indian Ocean, although in July 1943 it was temporarily directed to the South Atlantic. In 1945, the destroyer was assigned to the British Pacific Fleet, and on September 2, 1945, it was present in Tokyo Bay at the time Japan signed the act of unconditional surrender. After World War II, the destroyer was withdrawn from active operation, and it was scrapped in 1955.
