The Royal Australian Navy (RAN) is set to decommission its Adelaide-class guided-missile frigate, HMAS Sydney, after 32 years of service with the navy.
The warship will be decommissioned on 7 November, at her home port of Garden Island, Fleet Base East, Sydney.
Commissioned in January 1983, HMAS Sydney is the third warship in a series of six multi-purpose frigates.
Retired warrant officer marine technician Ian James Kemp, who served the navy for 40 years, has spent almost nine years on board HMAS Sydney.
Kemp said: "What I can say, is that one of my greatest highlights was when I was at the helm; when HMAS Sydney achieved her milestone of 500,000nm since her commissioning in 1983.
"It is hard to believe the time has come for Sydney to decommission."
Based on the US Navy Oliver Hazard Perry design, Adelaide-class frigates are long-range escort ships with roles including air defence, anti-submarine warfare, surveillance, interdiction, and reconnaissance.
The ships are capable of countering simultaneous threats from the air, surface and sub-surface.
These FFGs were the first RAN ships to be powered by gas turbines for main propulsion.
The RAN has already decommissioned the first two Adelaide-class frigates, HMAS Adelaide and HMAS Canberra.
