The 58-metre aluminium monohull patrol boat is the third of eight to be delivered to the Royal Australian Navy. The first two Evolved Cape-class Patrol Boats, ADV Cape Otway and ADV Cape Peron were delivered in March and August 2022, respectively.

The Evolved Capes feature new, larger amenities to accommodate up to 32 people, improved quality of life systems and advanced sustainment intelligence systems that further enhance the Royal Australian Navy’s ability to fight and win at sea.

The patrol boats will be utilised for a wide variety of constabulary and naval missions and play a critical role in Australia’s national security, as a high-performing, reliable and effective maritime asset.

In-service support for the Cape, Evolved Cape and Guardian-class Patrol Boat fleets operated by the Australian Border Force, Royal Australian Navy and Pacific Island nations is provided by Austal Australia through dedicated service centres located in Henderson, Western Australia; Cairns, Queensland; and Darwin, Northern Territory.

Each vessel has a crew of 18, and two crew groups are assigned to each vessel, alternating between operating the patrol boat and shore duties, to ensure maximum vessel availability.
