BAE Systems has completed on-dock production activities associated with the anti-ship missile defence (ASMD) upgrade of the Royal Australian Navy's sixth Anzac-class frigate, HMAS Parramatta.
The vessel was undocked after 600,000 hours of complex systems integration and engineering work at the Henderson facility.
HMAS Parramatta is now scheduled to undergo the test and trials phase.
BAE Systems Australia chief executive Glynn Phillips said: "Our highly skilled workforce is at the core of our capability, ensuring that the project achieves the quality, cost and schedule milestones despite the enormous complexity of such work.
"Our team, together with our Anzac Alliance partners, is very proud to support the Royal Australian Navy and its efforts by successfully implementing a world leading defence capability."
Under the ASMD programme, each ship will receive combat management system upgrades, the incorporation of an infrared search-and-track system, as well as phased array radar and a dual navigation radar system.
Additionally, BAE will perform a number of complex engineering and structural changes to the frigates, which include enclosing the quarterdeck and modifications to accommodate naval helicopters.
The ASMD programme involves 30 local and national subcontractors and more than 100 Australian suppliers.
The project is conducted through the Anzac Ship Integrated Material Support Programme Alliance comprising of BAE Systems, Saab Systems and the Defence Department's Capability and Sustainment Acquisition Group.
A total of eight Anzac ships are set to undergo ASMD upgrades.
HMAS Toowoomba is the next Anzac-class vessel scheduled to be undocked this year after receiving upgrades.
HMAS Stuart will be docked this year and is due for completion next year, while HMAS Ballarat, which is undergoing sea trials, will be accepted into active service.
