Australian shipbuilder Austal has completed the sea acceptance trials phase for the country's Patrol Boat Autonomy Trial (PBAT), the company announced on 23 April.

The milestone, which included an endurance trial, was achieved by the project's testbed – a decommissioned Armidale-class patrol boat now known as Sentinel. The vessel was formerly in service with the Royal Australian Navy as HMAS Maitland and retired in 2022.

To address the shortage of workers needed to build the number of ships needed to meet US Navy (USN) fleet plans, the country should seek to bring in more legal immigrants from foreign shores, according to US Secretary of the Navy Carlos Del Toro.
