The Cape class is a ship class of 10 large patrol boats operated by the Marine Unit of the Australian Border Force and Royal Australian Navy. Ordered in 2011, the vessels were built by Austal to replace Customs' Bay-class patrol boats, and entered service from 2013 onwards. Following availability issues with the Armidale class, two vessels were chartered by the Royal Australian Navy from mid-2015 to late 2016. A further two vessels were ordered at the end of 2015 by the National Australia Bank, who will charter the patrol boats to the Department of Defence from completion in 2017. A further six vessels were ordered in 2020.
