Navy Sea Systems Command has awarded a $291 million (AU$421.3 million) follow-on contract to Leidos, which has been tasked with supporting the Navy's Program Executive Office Integrated Warfare Systems Directorate.

The contract includes a one-year base period of performance with four additional one-year option periods, with work to be conducted across the globe.

As part of the contract, Leidos is expected to perform a range of support services, including shipboard modernisation, curriculum development, training conduct, depot support, technical data, maintenance planning and management.

Will Johnson, Leidos Senior vice president, logistics and mission support, welcomed the opportunity to expand the company’s offering to the US Navy.  

"We are honoured to continue our long-standing relationship with PEO IWS," he said.

“This award will enable Leidos to accelerate our support of their critical mission through modernization, domain expertise and innovation."

The announcement comes a week after the company’s Australian subsidiary, Leidos Australia, delivered new integration technology to the Australian Defence Force (ADF).

Defence confirmed the technology, dubbed “Wagardi” and developed as part of JP 2096, achieved final operational capability (FOC).

Wagardi is designed to accelerate the delivery of information users, improving decision-making in the battlespace.
