Nuclear-powered submarines
The Royal Australian Navy (RAN) currently operates six Collins-class submarines, which are diesel-electric vessels built in Adelaide, South Australia. However, the Australian government has announced plans to acquire nuclear-powered submarines as part of its naval fleet modernization. This initiative is being undertaken through a partnership with the United Kingdom and the United States, known as the AUKUS security partnership.
Under the AUKUS agreement, Australia will acquire a fleet of nuclear-powered submarines, known as the SSN-AUKUS class. The SSN-AUKUS submarines will be advanced vessels incorporating cutting-edge technologies from all three partner nations. The United States has authorized the sale of three Virginia-class SSNs to Australia, with the option to purchase two more. The first boat is planned to be delivered in the early 2030s.
The SSN-AUKUS class will be powered by Rolls-Royce pressurised water reactors (PWR) and will displace over 10,000 tonnes. They will be equipped with a vertical launch system capable of launching cruise missiles, such as the Tomahawk missile, and will have the ability to fire hypersonic and Mk-48 torpedoes. The first SSN-AUKUS boat is expected to be delivered to the Royal Australian Navy in the early 2040s, with construction beginning at the Osborne Naval Shipyard in South Australia by the end of the 2030s.
The addition of nuclear-powered submarines will provide Australia with a world-class capability and strengthen its strategic position in the region. It will be one of only seven countries operating nuclear-powered submarines, enhancing its naval capabilities and interoperability with its AUKUS partners. The SSN-AUKUS program also includes the development of a joint combat system and the sharing of components and parts with the US and UK navies.

Destroyers
The Royal Australian Navy (RAN) currently operates three Hobart-class guided missile destroyers: HMAS Brisbane, HMAS Hobart, and HMAS Sydney. These vessels are based on the Navantia-designed F100 frigate platform and are fitted with the Aegis Combat System, an advanced air defence solution capable of engaging threats at ranges beyond 150 kilometres. The Aegis system incorporates a state-of-the-art phased array radar and the SM-2 missile, enhancing the destroyers' defensive capabilities.
The Hobart-class destroyers were constructed in Australia by the Air Warfare Destroyer Alliance, with each ship assembled from 31 pre-fabricated modules or 'blocks'. These vessels measure approximately 150 metres in length and displace 7,000 tonnes. The design and platform integration were performed by a highly skilled team from Navantia Australia, who integrated modern weapon systems such as the Aegis Baseline 7.1 Refresh 2, the Tomahawk Weapon System, and the Saab Australian Interface.
As multi-purpose warships, the Hobart-class destroyers provide air defence not only for themselves but also for accompanying ships and land forces in coastal areas. They are equipped with long-range anti-ship missiles and naval guns, enabling them to engage in surface warfare and provide support to troops on land. Additionally, each Hobart-class destroyer carries a helicopter for surveillance and response, further enhancing their versatility.
In terms of appearance, the Hobart-class destroyers feature a sleek and modern design, incorporating the latest technological advancements. While the specific design details may be classified, these vessels are likely to have a streamlined profile, advanced sensors, and a range of weapons systems integrated into their superstructure. The destroyers are named after prominent Australian cities, with the possibility of a fourth vessel being named Melbourne or Adelaide.

Frigates
The Royal Australian Navy (RAN) operates seven Anzac-class frigates, which are mid-capability patrol frigates. The Anzac-class frigate originated from the RAN's New Surface Combatant (NSC) project, which began in the mid-1980s to find a replacement for the RAN's River-class destroyer escorts. The project settled on a ship of approximately 3,600 tonnes displacement, with a focus on anti-ship missile defence, damage control, and ship survivability. The Anzac-class frigates are also operated by the Royal New Zealand Navy (RNZN), which has two such vessels in its fleet.
The RAN also has plans to acquire six Hunter-class frigates, which will be built in Australia by ASC Shipbuilding, a subsidiary of BAE Systems Australia Ltd. The Hunter-class frigate is a modified version of BAE System's Type 26 frigate and is expected to be one of the most advanced anti-submarine warships in the world. It will provide the Australian Defence Force with high levels of lethality and deterrence and will have the capability to conduct a variety of missions, including humanitarian assistance and disaster relief.
In addition to the Anzac-class and Hunter-class frigates, the RAN also intends to acquire eleven general-purpose frigates, which will be among the navy's less capable 'Tier 2' warships. These frigates will be optimised for undersea warfare and will operate independently and in conjunction with the 'Tier 1' ships to secure maritime trade routes and escort military assets. The first three ships in the class will be built by a selected winning bidder, while the remainder will be constructed at the Australian Marine Complex in Western Australia.
The RAN's fleet also includes Hobart-class destroyers, Collins-class submarines, Canberra-class landing helicopter dock ships, Bay-class landing ship, Armidale-class patrol boats, Cape-class patrol boats, and Huon-class minehunters. The navy is continuously upgrading and replacing its vessels to ensure a modern and capable fleet.

Patrol boats
The Royal Australian Navy (RAN) operates a range of patrol boats, including the Armidale-class, Cape-class, Arafura-class, and the larger Offshore Patrol Vessels (OPVs). These vessels play a crucial role in protecting Australia's borders and interests, conducting civil surveillance, enforcing maritime law, and supporting environmental protection efforts.
The Armidale-class patrol boats have been in service since 2005 and currently comprise 12 active vessels. These boats are tasked with tracking, intercepting, and boarding suspicious vessels, and their crews are authorised to make arrests and seize cargo. In 2014, issues with hull cracking and corrosion were reported, leading to a mid-life refit program to extend their operational lifespan until a replacement class of larger vessels enters service.
The Cape-class patrol boats were built by Austal between 2012 and 2017 as replacements for the Bay-class. They operate from bases in Cairns and Darwin and are identified by their Australian Defence Vessel (ADV) prefix. Two additional Cape-class boats were commissioned to supplement the Armidale-class fleet.
The Arafura-class patrol boats are mentioned as part of the current RAN fleet, with one currently in service. They are also expected to be supplied by the Henderson Shipyard in Western Australia as "Tier 2 surface combatant" vessels.
Additionally, Australia has invested in the development of 12 OPVs to eventually replace the Armidale-class fleet. Luerssen Australia Pty Ltd was selected as the main contractor for the SEA1180 Offshore Patrol Vessel program, with a US$3.6 billion contract. These larger vessels will enhance the RAN's capabilities in patrolling Australia's vast maritime zones.

Ship colour schemes
The colour scheme of a ship in the Australian Navy depends on its class and purpose. For instance, the Australian Navy's Cape-class patrol boats feature two distinct colour schemes. The ADV Cape Fourcroy and ADV Cape Inscription retain the blue-and-red customs colour scheme, while the Evolved Cape-class ships have a grey naval colour scheme.
The colour scheme of a ship can also change over time, as ships are upgraded or replaced. For example, the Australian Navy's Anzac-class frigates, which were first put into service 28 years ago, are being retired and replaced. Similarly, the Collins-class submarines, which have been in service since 1993, are slated to be replaced by nuclear-powered submarines with superior stealth, speed, and range capabilities.
The colour scheme of a ship can also depend on its intended theatre of operations. For instance, the OPVs, or "minor war vessels," will be focused on "civil maritime security operations" and "regional engagement" in the southwest Pacific and southeast Asia. The colour scheme of these vessels may be chosen to better camouflage them in these specific regions.
Additionally, the colour scheme of a ship can be dictated by its role within the Navy. For example, the Supply-class replenishment oilers, which provide replenishment at sea, may have a different colour scheme than the combat-focused Anzac-class frigates.
Finally, historical factors can also play a role in a ship's colour scheme. During World War I, the light cruiser Sydney's four funnels were camouflaged to make the ship less visible to enemy forces.

Frequently asked questions
The Royal Australian Navy (RAN) fleet is made up of warships and non-commissioned vessels. The warships include destroyers, frigates, submarines, patrol boats, supply ships, landing helicopter dock ships, and landing ships. The non-commissioned vessels are identified with the prefix ADV (Australian Defence Vessel) and include patrol boats and hydrographic survey vessels. The RAN fleet is quite diverse in terms of appearance, with different classes of ships serving different purposes.
Here are some examples of Australian Navy ships and a brief description of their appearance:
- Hobart-class destroyers: These are large, powerful ships that are almost 148 meters long and weigh 7,000 tonnes each. They are designed to protect other ships, troops, and defence infrastructure near the coast.
- Anzac-class frigates: These frigates are starting to get old, with the first one, HMAS Anzac, being retired after 28 years of service.
- Collins-class submarines: These are diesel-electric submarines that began entering service in 1993. They were designed by Swedish submarine builder Kockums specifically to meet Australian requirements, including the need for great range without nuclear propulsion.
- Cape-class patrol boats: These are relatively smaller vessels that operate from bases like HMAS Cairns and HMAS Coonawarra in Darwin. They are identified by their Australian Defence Vessel (ADV) prefix and blue-and-red customs colour scheme.
Yes, the Australian government and the Royal Australian Navy have announced plans to upgrade and expand the surface naval fleet. The plan includes increasing the "surface combatant fleet" from 11 to 26 "tier one" and "tier two" ships. The "tier one" ships will be built at the Osborne shipyards in Adelaide, including the construction of nuclear submarines through the AUKUS partnership with the US and UK. The “tier two" ships will be built at the Henderson shipyards in Perth, including the Evolved Cape-class patrol boats.
During World War I, the Royal Australian Navy (RAN) played a significant role alongside the Grand Fleet and other Allied navies. The RAN began the war with 16 ships and ended with 37 ships, including cruisers like the Sydney, which was involved in early naval operations and the sinking of a German ship. The light cruiser Sydney is also mentioned, which had its four funnels camouflaged during patrols off Long Island and around the Caribbean in 1916.
