About this opportunity
The Department of the Navy Naval Supply Systems Command has awarded contract N0018926RB001 to BAE Australia Limited for ROTHR DDRx system sustainment support services on a sole-source basis, with award effective June 25, 2026.
The justification cites 10 U.S.C. 3204(a)(1) as implemented by FAR 6.302-1, establishing BAE Australia as the only responsible source. The DDRx technology is proprietary to BAE and cannot be repaired by other companies. Previous DDRx contracts with BAE (DIA contract HHM402-15-C-0059 and Navy contract N00189-22-C-Z021 valued at $34.8 million) established BAE's exclusive capability. Memoranda of Understanding between the U.S. Department of War and Australian Department of Defense signed in August and September 2020 prohibit transfer of Australian defense articles to third parties, preventing other contractors from performing sustainment services. A sources sought notice posted January 8, 2025, and January 28, 2026, resulted in minimal interest with no viable alternate sources.
Required services include maintenance, technical support, software support, risk management framework support, and asset retrograde repair and return processes for the ROTHR system, a land-based high-frequency radar providing wide-area surveillance at three locations: Virginia, Texas, and Puerto Rico. The contract structure includes a base year plus four one-year options, with primary performance at ROTHR Texas and BAE Australia facilities. Services for Virginia and Puerto Rico will be included in option years following delivery of respective DDRx systems. Funding derives from FY26 Operations and Maintenance appropriations. The Contracting Officer determined the anticipated cost is fair and reasonable.
