725 Squadron is a naval aviation squadron of the Royal Australian Navy (RAN) Fleet Air Arm. The squadron was originally created in August 1943 as part of the Fleet Air Arm of the Royal Navy. It initially served as a fleet requirements unit, was rerolled in August 1945 as a target towing unit, then was disbanded in December 1945. In January 1958, the squadron was re-formed, as a fleet requirements and communications unit of the RAN, operating a variety of fixed-wing aircraft. The squadron was redesignated as an anti-submarine warfare training squadron in May 1959, then was decommissioned in May 1961 and absorbed into 724 Squadron. 725 Squadron was recommissioned in November 1962 as an operational anti-submarine helicopter squadron, flying the Westland Wessex. During this commission, the squadron was involved in HMAS Sydney's troop transport voyages, the rescue of personnel following the Melbourne-Voyager collision, and the Operation Navy Help Darwin relief effort post-Cyclone Tracy. The squadron was decommissioned in December 1975. 725 Squadron was commissioned for the fourth time in June 2015, this time as a training unit for MH-60R Seahawk Romeo helicopters: the squadron had been reactivated two years prior as a non-commissioned unit train on and accept into service the Romeos.
