HMAS Watson is a Royal Australian Navy (RAN) base on Sydney Harbour at South Head, near Watsons Bay in Sydney, Australia. Commissioned in 1945 (after three years operating as HMAS Radar), the base served as the RAN's radar training school. In 1956, torpedo and anti-submarine warfare training were relocated to the base, and by 2011, Watson was the main maritime warfare training base, as well as providing post-entry education for maritime warfare officers, training for combat system and electronic warfare sailors, and command training.
