About this opportunity
The Department of the Navy Naval Supply Systems Command issued a sole source justification notice on December 16, 2025, for technical assistance to troubleshoot and repair the No. 1 High Pressure Air Compressor (HPAC) First Stage cooling system aboard a submarine. The contract, awarded on December 12, 2025, was justified as a sole source procurement based on RIX Industries' status as the sole authorized Original Equipment Manufacturer in the United States with exclusive proprietary access to the technical drawings, expertise, and components required for the 5R5-75B HPAC unit used in submarine applications. RIX Industries was selected as the awarded vendor because all components and parts are proprietary to the company and mandated by NAVSEA for submarine use, making them the only viable source capable of performing this complex, highly engineered repair work. The justification was supported by Casualty Report (CASREP) 25067 and processed under the Simplified Acquisition Threshold, though the specific contract award amount was not disclosed in the notice. This non-nuclear ship repair procurement falls under PSC Category J999 and addresses an urgent operational requirement to restore critical submarine equipment functionality.
