NAVSUP Weapon Systems Support Philadelphia intends to sole-source the purchase of four indicator panels (P/N 06550-00835-102) from Sikorsky Aircraft Corp, the OEM and only known approved source. No drawings or data are available, and the Government does not own the rights needed to source this part elsewhere. Non-approved firms may submit a Source Approval Request, but the procurement will not be delayed for SAR approval, and this notice is not a request for competitive proposals. The acquisition will use FAR Part 15 procedures rather than FAR Part 12 commercial-item policies, with electronic solicitation procedures via NECO and delivery FOB origin. The anticipated award date is November 2026.
