The Royal Australian Navy’s (RAN) second Supply-class auxiliary oilier replenishment (AOR) vessel NUSHIP Stalwart has set sail to undergo its final fitout.

The two Supply-class AOR ships are built by Navantia as part of a contract awarded in May 2016.

NUSHIP Stalwart departed from Pier 12 in Navantia’s Ferrol shipyard for Australia.

The Australian industry will conduct and complete installation and testing of the ship’s combat and communications systems, and certain logistics areas.

Last month, the RAN commissioned the first Supply-class AOR ship ‘HMAS Supply’.

The Supply-class ships will replace existing vessels retired, HMAS Success and HMAS Sirius.

The AORs will be used for carrying fuel, water, food, parts and dry cargo. They will primarily provide logistics replenishment to naval combat units at sea and bridge the current capability gap.

Furthermore, the ships will support Humanitarian and Disaster Relief (HDR) operations domestically and regionally.

Spain Australian ambassador Sophia McIntyre said: “Navantia’s role in constructing four classes of ship for Australia has formed an important plank in the development and evolution of our political, economic, military and cultural ties.

“It’s an honour for Australia to have taken its place as a part of Galicia’s historic and impressive tradition of ship building. Navantia will continue to play a crucial role in providing platform support for these ships in Australia.”

Supply and Stalwart feature Integrated Platform Management System (IPMS) built by NSAG, Navantia’s JV with Adelaide-based SAGE Automation.

Saab and Raytheon are supplying the combat management systems and communications systems, respectively.

Once the second AOR enters service, the total count of operational naval units designed by Navantia for the Royal Australian Navy will be 19.

Besides supporting the life cycle of AOR vessels, Navantia Australia was also involved in the support of other naval units.
