It was allocated to10 Squadron, which then operated out of Townsville, as an Anti-Submarine Reconnaissance aircraft, and was one of a total of 24 Neptunes operated by RAAF 10 and 11 Squadrons. It served with 10 Squadron from March 1962 until being retired from RAAF service in May 1977 when it was placed in storage at Townsville awaiting disposal. During its years of service A89-273 logged a total of 5476 flying hours.

Long after the aircraft was de-commissioned it was acquired from a private owner in Townsville by members of the Society in a partly restored condition.

Since its total restoration over 10 years ago, this aircraft has been on the Air Show circuit thrilling audiences with an imaginative flying routine.  In November 1996, the Society commenced an extensive maintenance program on Neptune A89-273 from nose to tail, culminating in the aircraft being declared airworthy again in January 1998. All maintenance was carried out by our own engineering team.

In November 1999, the Society had great pride in returning 273 back to its old squadron at Edinburgh Air Force Base in South Australia to celebrate the 60th Anniversary of the formation of 10 Squadron in 1939. Edinburgh is now the home base for this squadron. Neptune A89-273 VH-IOY is the only former RAAF Lockheed Neptune flying in Australia and is maintained, operated and crewed by members of HARS who maintain a high degree of maintenance and safety, and continually strive to maintain the aircraft in immaculate condition. With large amounts of spare parts and engines available it is anticipated that Neptune A89-273 will continue to be maintained in a flying condition and appearing at air shows throughout Australia for many years to come.

In 1987 a representative from HARS attended a conference held in Tahiti and contact was made with the French Embassy in respect to obtaining a French Neptune. Upon arrival at Tahiti-FAAA (Papeete’s International Airport) three were sighted, one partially burnt, one stripped of its engines and the other (147566) appeared to be intact. These three Neptune aircraft were all that remained of Escardrille 12. An inspection of Neptune 566 revealed that although some instruments were missing, the aircraft was in sound condition and its tanks still contained 2000 lbs of fuel. The aircraft was located in an area that could easily be described as a swamp, into which it was slowly sinking.

The original intention was to acquire and dismantle the aircraft as a source of spare parts for the Society’s other Neptune (273), however after viewing the documentation, the decision was made to restore the aircraft to flying condition in Tahiti and fly it back to Australia. It had flown a total of 2,430 hours and was considered to be in excellent condition as the aircraft had been extensively overhauled just prior to being de-commissioned in 1983.

After further negotiations the title was transfered to HARS. There were a number of trips to Tahiti before Neptune 566 was finally made ready by HARS members for the ferry flight to Australia in July 1989. Neptune 566 was placed on the Australian civil register as VH-LRR, and after a number of public appearances at air shows, was positioned to Tamworth for storage and care. In September 1999 the aircraft was ferried from Tamworth to Bankstown and than in January 2003 it was flown to the new HARS base at the Illawarra Regional Airport where the overhaul work continues pending return to full flying status.
