Summary
This Justification and Approval (J&A) for the use of other than full and open competition, specifically J&A FY 26-059, was issued by the NAVSUP Fleet Logistics Center Norfolk.
The justification outlines a sole source contract award to BAE Australia Limited for system sustainment support services related to the Direct Digital Receivers (DDRx) used in the Relocatable Over-the-Horizon Radar (ROTHR) system, which operates in Texas, Virginia, and Puerto Rico. The total estimated value of this contract includes a base year plus four one-year options, with funding sourced from FY26 Operations and Maintenance appropriations.
BAE Australia is uniquely qualified to provide these services due to its proprietary technology associated with the DDRx systems, which were originally developed and produced under previous contracts.
The justification cites statutory authority under 10 U.S.C. 3204(a)(1), indicating that only one responsible source can meet the agency's requirements. It emphasizes that utilizing another contractor would pose significant risks to technical performance and violate existing Memoranda of Understanding between the U.S. and Australian governments regarding defense articles and services.
The required sustainment services are critical for maintaining operational readiness of the ROTHR systems, which play a vital role in counterdrug operations by providing surveillance capabilities against drug smuggling activities.
