We're proud to announce the successful launch of Hull 544 — the final Guardian-class Patrol Boat contracted for construction under the Pacific Patrol Boat Replacement Project (SEA3036-1) for Defence Australia.

The launch marks a significant milestone in the (now) 24 vessel program that began in May 2017 with the plate cutting on the first Guardian, HMPNGS Ted Diro; and has seen 22 vessels delivered to date, to support maritime security across the Pacific.

Every Guardian-class Patrol Boat constructed by Austal here in Henderson Western Australia reflects the skill, dedication and resilience of our #team and our supply chain and industry partners. 

Through challenges and change, we have worked collaboratively to refine processes, strengthen capability and establish a highly efficient steel shipbuilding production line.
