ADV Cape Otway

Australian Defence Vessel (ADV) Cape Otway, named after Cape Otway, is an evolved Cape-class patrol boat of the Royal Australian Navy (RAN).

It is the first of eight evolved Cape-class patrol boats to be delivered to the RAN. Prior to Cape Otway, the RAN already operated the Cape-class patrol boats ADV Cape Fourcroy and ADV Cape Inscription.

It was built by Austal in Henderson, Western Australia, commissioned on 23 March 2022 and based at HMAS Cairns (naval base) in Queensland, where it arrived in June 2022. The patrol boat's primary duty lies in fisheries protection, immigration, customs and drug law enforcement operations.

The ship is one of the original six evolved Cape-class patrol boats the RAN ordered in April 2020 to replace the Armidale-class patrol boats in this role, at a projected cost of A$324million. This order was subsequently expanded by another two boats in April 2022, at an additional projected cost of $124million. In November 2023, the RAN ordered a further two evolved Cape-class patrols, at a cost of A$157.1million.
