About this opportunity
The Department of the Navy Naval Sea Systems Command awarded a firm-fixed-price contract valued at $8,346,868 to Northrop Grumman Systems Corporation on August 26, 2026 for maintenance, repair, and overhaul of the No. 1 and No. 2 ship's service turbine generators aboard USS New Hampshire (SSN-778).
Work is performed at Norfolk Naval Shipyard. The contract spans three service phases across fiscal years 2026–2028, funded through Operations and Maintenance (O&MN) accounts. Services include disassembly, inspection, repair, tuning and balancing of SSTG components; removal and installation of existing and new OEM components; and replacement of No. 1 and No. 2 SSTG Inboard and Outboard Thrust Stator and Catcher Bearings. OEM materials and specialized tooling carry a minimum 637-day lead time.
The award was made as a sole source contract without full and open competition. Northrop Grumman's status as OEM maintains proprietary tooling, equipment, drawings, and components essential to SSTG maintenance. A Sources Sought Notice issued February 28–March 10, 2023 yielded no alternative qualified sources. Historical Navy contracts demonstrate Northrop Grumman has exclusively provided virtually identical SSTG repair services for multiple vessels under prior sole source awards.
