HMAS Otway (S 59) was an Oberon-class submarine operated by the Royal Australian Navy, notable for its significant service during the Cold War era. Constructed in Scotland by Scotts Shipbuilding and Engineering Company, she was laid down on 29 June 1965 and launched on 29 November 1966, being the first RAN submarine launched by a member of the Royal Family, Princess Marina. Otway was commissioned into the RAN in April 1968 and arrived in Australian waters later that year, after a voyage that included the first RAN visit to Ghana and the first Australian submarine to round the Cape of Good Hope. Measuring approximately 295.2 feet (90 meters) in length with a beam of 26.5 feet (8.1 meters) and a draught of 18 feet (5.5 meters), Otway had a surfaced displacement of about 2,030 tons and 2,410 tons when submerged. Powered by two English Electric motors and two Admiralty Standard Range diesel generators, she could reach speeds of up to 12 knots on the surface and 17 knots submerged, with a range of 9,000 nautical miles at 12 knots. Her test depth was 200 meters. Her armament comprised six 21-inch torpedo tubes, initially armed with British Mark 8 torpedoes, later upgraded to the wire-guided Mark 23, and eventually to U.S. Navy Mark 48 torpedoes and Sub Harpoon missiles. The vessel also had short stern torpedo tubes for anti-submarine torpedoes, which were later removed. Throughout her service, Otway participated in various exercises, including SEATO operations, and undertook notable missions such as escorting the last Royal Navy submarine in Australian waters. She experienced minor damage during training exercises, notably when struck by a dummy torpedo and a whale, both repairs completed swiftly. Decommissioned in 1994, Otway’s upper casing, fin, and stern are preserved at Holbrook, New South Wales, serving as a memorial. Her legacy remains significant in Australian naval history, exemplifying Cold War submarine capability and fostering community remembrance through her preserved sections and associated museum.
