# U.S. Navy Trains RAN Maintainers in Hawaii

A U.S.-led training rotation at Pearl Harbor Naval Shipyard and Intermediate Maintenance Facility equipped 20 Royal Australian Navy Fleet Support Unit sailors to help maintain U.S. and U.K. nuclear-powered submarines, building sustainment capacity under AUKUS. A further U.S. submarine maintenance period in Western Australia is scheduled by the end of 2026, and submarine rotations from HMAS Stirling are planned to begin in 2027. No contract award, solicitation, or contract value was identified.

- The effort points to continued demand for submarine maintenance expertise, workforce training, and sustainment infrastructure. ASC Pty. Ltd. is identified as a civilian sustainment provider training to lead intermediate- and depot-level maintenance.
- Contractors supporting submarine sustainment can assess whether their maintenance, training, or infrastructure capabilities align with the developing Australia-based support model; the signal does not identify a specific procurement opportunity or solicitation.
- The Western Australia maintenance period is scheduled for the remainder of 2026, with HMAS Stirling rotations planned from 2027, providing relevant planning milestones for organizations supporting AUKUS sustainment.
