Austal Limited (ASX:ASB) is pleased to announce that Austal Australia has been awarded a contract extension for the construction of two additional Evolved Cape-class Patrol Boats, to be delivered to the Australian Border Force (ABF). The A$137.02 million contract brings the total number of Evolved Cape-class Patrol Boats to be constructed by Austal to 12, with eight delivered to date.
December 23, 2024 -- Austal Limited Chief Executive Officer Paddy Gregg said the two additional Evolved Cape-class Patrol Boats for the ABF will further enhance the capabilities of Maritime Border Command and ‘Operation Sovereign Borders’, tasked with the ongoing protection of Australia’s maritime borders.
“The eight Evolved Capes delivered by Austal since 2020, operating with the Royal Australian Navy, are making a significant contribution to our maritime and border security. These additional vessels for the Australian Border Force will further enhance the capability for maritime surveillance and border patrols throughout Northern Australia.
“Austal previously delivered eight, original Cape-class Patrol Boat fleet to the Australian Border Force from 2012 to 2015; it’s a testament to the vessel’s capability and our team’s shipbuilding expertise that we’re now tasked with constructing two Evolved Capes for the ABF; their first Evolved Capes, to enhance their existing capabilities for this important mission,” Mr Gregg said.
