NAVSUP Weapon Systems Support Philadelphia intends a sole-source procurement of one ESM REC PROCESSOR (NSN 9999LLW2AA020, P/N 279A146-1). No drawings or technical data are available, and the Government does not own or have rights to the needed data, so the approved source is expected to receive the award. Firms not already approved must submit a Source Approval Request (SAR), and this procurement will not be delayed pending SAR approval. The acquisition will use FAR Part 15 procedures, is not a Total Small Business Set-Aside, and will be conducted electronically via NECO. The anticipated award date is December 2026; interested organizations may email capabilities and qualifications to lauren.n.phillips6.civ@us.navy.mil.
