The Cape-class is a ship class of 26 large patrol boats operated by the Marine Unit of the Australian Border Force (ABF), the Royal Australian Navy (RAN) and the Trinidad and Tobago Coast Guard. First ordered in 2011, the vessels were built by Austal to replace Customs' Bay-class patrol boats, and entered service from 2013 onwards. Follow on orders were made in 2015 then 2018 by the RAN to augment, then eventually replace its Armidale class patrol boats. More orders were then made by the ABF from 2024 onwards to replace the remaining Bay class patrol boats and expand its patrol boat force.
