NAVSUP Weapon Systems Support Philadelphia intends to award a sole-source contract to Robertson Fuel Systems, LLC for repair of MH-60R helicopter aircraft fuel tanks (NIIN 015656152, P/N HMO43-010-11, quantity 4 EA, FOB origin). Robertson is the OEM and only known source, and the Government lacks the drawings/data or rights needed to source this part elsewhere. The procurement has a one-year contract duration, anticipates award in March 2027, and will use FAR Part 15 and FAR Part 12 commercial procedures with UID and Buy American clauses. Non-approved firms would need to submit a Source Approval Request, but the procurement will not be delayed for SAR approval; this is not a Total Small Business Set-Aside. Interested parties may email Devon McNamee to provide capability information, though this is not a request for competitive proposals and the agency intends to proceed sole source.
