The Naval Surface Warfare Center, Philadelphia Division (NSWCPD) is issuing a Request for Information (RFI) to identify sources for depot-level repair services for the U.S. Navy M250-KS4 Marine Gas Turbine Engines (MGT). These engines are used on DDG-51 Class ships and LCS Freedom Variant vessels. Offerors must be Rolls-Royce Authorized Maintenance Repair and Overhaul Centers (AMROC) for the M250 family of engines, demonstrating access to all required OEM drawings, repair procedures, and specialized tools. Contractors must have an operational test cell and repair facility capable of functional and performance testing, including vibration, starting, restarting, and acceleration. The RFI lists specific OEM specialized tools and equipment required for disassembly, repair, and reassembly. Vendors are requested to provide company information, proof of AMROC agreement, ability to meet a 180-day Repair Turn-Around-Time (RTAT), typical capabilities, equipment origin, user references, and warranty information by June 3, 2026. This RFI is for informational purposes only and is not a request for proposal.

This Statement of Work (SOW) outlines the requirements for the repair of Model M250-KS4 Marine Gas Turbine Engines for the Naval Surface Warfare Center Philadelphia Division (NSWCPD).
