List of active Royal Australian Navy ships

The Royal Australian Navy (RAN) fleet is made up of 31 commissioned warships and 16 non-commissioned as of April 2024^[update].

The main strength is the seven frigates and three destroyers of the surface combatant force: seven Anzac class frigates and three Hobart class destroyers. Six Collins-class boats make up the submarine service, although due to the maintenance cycle not all submarines are active at any time. Issues present early in the service life of the submarines have now been fixed and five submarines are mission capable. Amphibious warfare assets include two Canberra-class landing helicopter dock ships and the landing ship HMAS Choules. Four Armidale-class patrol boats perform coastal and economic exclusion zone patrols, and four Huon-class vessels are used for minehunting and clearance (another two are commissioned but in reserve since October 2011, for sale as 2018). Replenishment at sea is provided by two Supply-class replenishment oilers, while the two Leeuwin-class perform survey and charting duties.

In addition to the commissioned warships, the RAN operates the sail training ship Young Endeavour, eight Cape-class patrol boats and seven ships making up the National Support Squadron. Other auxiliaries and small craft are not operated by the RAN, but by DMS Maritime, who are contracted to provide support services.^[1]

The majority of the RAN fleet is divided between Fleet Base East (HMAS Kuttabul, in Sydney) and Fleet Base West (HMAS Stirling, near Perth). Mine warfare assets are located at HMAS Waterhen (also in Sydney), while HMAS Cairns in Cairns and HMAS Coonawarra in Darwin host the navy's patrol and survey vessels.

For over 30 years, the Osborne Naval Shipyard in South Australia has been the main supplier of 'Tier 1 combatant' vessels to the RAN, having constructed the entire Collins-class submarine fleet and Hobart-class destroyer fleet. Osborne will further supply the navy with the currently under-construction Hunter-class frigate vessels, aswell as SSN-AUKUS nuclear-powered attack submarines and Hobart class guided-missile destroyer replacements. The Henderson Shipyard in Western Australia will supply the RAN with smaller 'Tier 2 surface combatant' vessels. These include Australian general purpose frigate's, Large Optionally-Crewed Surface Vessel's (LOSV), and Cape class and Arafura class patrol boats.
