About this opportunity
The Portsmouth Naval Shipyard is seeking repair and maintenance services for Ship Service Turbine Generators #1 and #2 aboard naval vessels. The Department of the Navy Naval Sea Systems Command will procure these specialized shipboard maintenance services under the authority of FAR 6.301-1, which allows for sole source procurement when only one responsible source exists. The contract requires proprietary expertise for turbine generator systems, including access to original equipment manufacturer drawings, equipment specifications, and approved repair processes. The solicitation is expected to be released on or around October 25, 2025, with the current pre-solicitation notice posted on September 23, 2025, and responses due by October 15, 2025. A justification and approval document for the sole source procurement approach will be made available separately.
This procurement does not include any set-aside designations and will be awarded as a sole source contract to Northrop Grumman Marine Systems (NGMS), identified by CAGE Code 90099. NGMS qualifies as the only capable contractor because they are the Original Equipment Manufacturer for the Ship Service Turbine Generators and possess the proprietary data rights necessary for the work. The contract falls under NAICS code 336611 for Ship Building and Repairing and PSC code 2830 for Water Turbines and Water Wheels and Components. No specific contract value, quantities, or performance timeline details were disclosed in this pre-solicitation notice. The work involves maintenance and repair of two distinct turbine generator units designated as SSTG #1 and #2.
