725 Squadron History

725 Squadron has its origins in the Royal Navy (RN) where it was formed as a Fleet Requirements Unit on 27 August 1943. The Squadron's aircraft and operations were varied before moving to Cornwall to become an Air Target towing unit in August 1945. The Squadron was disbanded in December that year.

725 Squadron recommissioned in the Royal Australian Navy (RAN) at Naval Air Station (NAS) Nowra as a Fleet Requirements and Communications Unit on 13 January 1958. Under the command of Lieutenant Commander John Brown, the Squadron flew a variety of aircraft including Douglas C47A Dakota, Auster J5-G Autocar, Hawker Sea Fury Mark 11, Fairey Firefly AS-5 and Fairey Gannet AS1. In May 1959, the Squadron's role was changed to Anti-Submarine Warfare (ASW) training.

725 Squadron suffered its only fatality on 28 December 1959 when Sub Lieutenant LA Mauritz's Gannet crashed attempting to land at NAS Nowra. The Gannet's unusual twin engine configuration, driving two counter rotating propellers located one behind the other, enabled the Gannet to fly with only one engine engaged in order to conserve fuel and extend endurance, however, both engines had to be engaged when taking off or landing. Mauritz was attempting a single engine landing with tragic consequences.

Part of 725 Squadron's responsibilities was to provide interception practice for Direction Officers training at HMAS Watson in the Radar Plot branch. The Squadron also provided aircraft for ships working up at sea near Jervis Bay performing varied tasks such as radar and communications calibration exercises through to mock attacks with multiple aircraft.

The Squadron was decommissioned on 31 May 1961 and absorbed into 724 Squadron.

725 Squadron recommissioned on 1 November 1962 flying the first two Westland Wessex 31A helicopters delivered to the RAN for ASW training and support to 817 Squadron, the Fleet Air Arm's (FAA) front line Wessex Squadron. 725 Squadron was eventually equipped with ten Wessex helicopters.

On 10 February 1964 at 8:56pm, HMAS Melbourne (II) collided with HMAS Voyager (II) in one of the most tragic accidents in Australian naval history. The disaster resulted in the loss of 82 lives, all from Voyager. 725 Squadron participated in search and rescue efforts in the aftermath of the collision.

The Squadron also embarked in HMAS Sydney (III) throughout the 1960s, providing anti-submarine escort duties during her many troop transport voyages to Vietnam, a responsibility it shared with 817 Squadron. The Wessexes were equipped with dipping sonar and an offensive armament of torpedoes and depth charges in its ASW role. While in the operational area, the normal routine was to have one Wessex screening the ship while another was fully armed and prepared on her deck. Shortly afterwards the RAN's FAA Squadrons adopted US Navy prefixes and 725 Squadron became HT725 Squadron indicating that it was classed as a rotary wing training unit.

The FAA became embroiled in industrial unrest in July 1974 when the Storeman and Packers Union black banned the RAN resulting in fuel shortages and flying restrictions. This became a serious, and even life threatening, issue the following month when heavy rain and flooding inundated the Nowra area. The FAA, including HT725 Squadron, was called upon for disaster relief operations but the fuel shortage gave rise to concerns about whether rescue efforts would have to cease. Eventually common sense prevailed and fuel tankers began to arrive allowing personnel from NAS Nowra to rescue some 352 people.

725 Squadron decommissioned on 27 December 1975.

In June 2011, the Government announced the acquisition of 24 Sikorsky MH-60R Seahawk ‘Romeo’ naval combat helicopters as replacements for the Sikorsky S-70B-2 Seahawks. On 13 December 2012, it was announced that 725 Squadron would recommission as the new training squadron for the Romeo aircraft while 816 Squadron will be the operational support squadron. NUSQN 725 was stood up on 11 February 2013 under the command of Commander David Frost, RAN. The acquisition of the Romeo was for a ‘total package’ including training, technical and logistic support from the United States Navy (USN).

The Squadron’s aircrew and maintainers are training at Naval Air Station (NAS) Jacksonville and Naval Station (NS) Mayport, both located in Jacksonville, Florida, USA. The first group of more than 30 maintainers left Australia on 8 March 2013 and began their training at NAS Jacksonville’s Center for Naval Aviation Technical Training Unit on 1 April. By the time the Squadron returns to Australia in 2015, around 65 maintainers will be qualified to service and repair the Romeos.

The first aircrew were certified to fly the Romeo on 16 August 2013 and six days later, the Squadron moved into its own hangar space in building 1122 at NAS Jacksonville.

Carrying the tail number N48-001, Australia's first Seahawk Romeo completed its initial test flight at Sikorsky's production facility in Stratford, Connecticut, on 26 June 2013. The helicopter successfully passed a range of tests during the 1 hour and 20 minute sortie including controllability, engine performance, vibration analysis and navigation. A second sortie later that day completed the 'Contractor Flight Acceptance' phase.

NUSQN 725 moved into its own hangar space in building 1122 at NAS Jacksonville on 22 August and took delivery of their first two aircraft on 12 December 2013. The two Romeos were formally accepted into RAN service by NUSQN 725 on 24 January 2014 at a ceremony attended by the Squadron, their American counterparts, family members, the Australian Defence attaché in Washington, Rear Admiral Steve Gilmore, and the commander of the USN 4th Fleet, Rear Admiral Sinclair Harris, USN.

The next two aircraft arrived at Jacksonville in late February 2014 along with a non-flying MH-60R ‘Bromeo’ maintenance training aid airframe, the first of two, which will be used to train aircrew and maintainers. The Bromeo is a cost-effective way to expedite training free from the constraints of flying and operational commitments of in service aircraft. At around the same time another group of aviation maintainers arrived bringing the total of RAN FAA personnel at Jacksonville at that time to 95. That number increased to 112 by October when the first Romeo was delivered to Australia, and all had returned to Nowra by the end of the year.

In the last week of August the squadron participated in Exercise GREY FOX, the biggest missile firing exercise ever undertaken by the USN’s Helicopter Maritime Strike Wing Atlantic. The Strike Wing was responsible for seven USN Romeo squadrons and was also supporting NUSQN 725 in the USA. The exercise involved the coordinated delivery of 29 Hellfire missiles, nine of which were fired by NUSQN 725, the most of any squadron across the Strike Wing. The ability to make such a significant contribution to the exercise was a testament to the dedication of both the deployed members of the squadron and the support they had received from their USN counterparts. The Squadron continued to make use of the opportunity to participate in large scale international exercises while in American waters.

Just one month later NUSQN 723 would fire nine Hellfire missiles during Exercise GREY FOX.

The first Romeo arrived at HMAS Albatross on 14 October 2014 along with the Bromeo training airframe and moved into brand new facilities at the air station. They were transported aboard a Royal Australian Air Force C-17A Globemaster from NAS Jacksonville and were followed by two more Romeos over the following three weeks. That same month the squadron surpassed 1,000 flight hours in the Romeos while undergoing training in the USA.

The Romeo made its maiden Australian flight on 14 November 2014 when the crew of Lieutenant Commander Todd Glynn, Lieutenant Craig Castle and Leading Seaman Liam Carruthers flew the helicopter from Albatross to Sydney. The aircraft flew over Sydney Harbour and hovered over some of the city’s most iconic sites where Sydneysiders gave the helicopter a rousing reception.
