HMAS Waller (SSG 75) is a distinguished Collins-class submarine operated by the Royal Australian Navy, named after Captain Hector Waller, a notable naval officer from World War II. Laid down on 19 March 1992 and launched on 14 March 1997, Waller was commissioned into service on 10 July 1999. Constructed by Australian Submarine Corporation (ASC), she is part of a class that is an enlarged version of the Swedish Västergötland class, making her the largest conventionally powered submarine in the world at 77.42 meters in length, with a beam of 7.8 meters and a waterline depth of 7 meters. She displaces approximately 3,051 tonnes on the surface and 3,353 tonnes when submerged. Her hull is built from high-tensile micro-alloy steel and fitted with anechoic tiles to reduce sonar detection. Waller's armament includes six 21-inch torpedo tubes, capable of carrying up to 22 torpedoes, including the Gould Mark 48 and UGM-84C Sub-Harpoon, with upgrades to the Mark 48s to the CBASS version. Her propulsion system comprises three Garden Island-Hedemora HV V18b/15Ub diesel engines, generating electricity stored in batteries, which powers a single 7,200 shaft horsepower DC motor connected to a seven-bladed propeller. She can reach speeds of 10.5 knots on the surface and 21 knots submerged, with an operational range of up to 11,000 nautical miles at 10 knots. Her endurance lasts approximately 70 days. Waller has an active operational history, including participation in international war games, notably operating as part of a U.S. Navy carrier battle group in 2000, where she performed well in simulated engagements against nuclear submarines. She has demonstrated her capabilities in exercises such as RIMPAC 2000 and Operation Tandem Thrust in 2001, sinking surface and submarine targets, including a Los Angeles-class submarine and a decommissioned USS Fletcher during RIMPAC 2008, marking her as a significant asset in submarine warfare. Throughout her service, Waller has faced maintenance and safety challenges, including a fire in 2014 and another in 2021, both of which were successfully managed with repairs completed. Her operational history highlights her role in enhancing Australia's underwater defense capabilities and her participation in multinational exercises, underscoring her importance in regional maritime security.
