NAVSUP Weapon Systems Support Philadelphia intends to solicit a limited-source procurement for 39 units of a signal data converter (NSN 7RH 5895 014608011 XH, P/N PS491-1), delivered FOB origin. The Government lacks drawings/data and does not own the necessary data rights, so it expects award to the approved source; non-approved firms must submit a Source Approval Request, and the procurement will not be delayed for SAR approval. This is a total small business set-aside under FAR Part 15, not FAR Part 12 commercial procedures, and all responsible sources may submit capability statements, proposals, or quotations. Electronic procedures will be used, with the solicitation posted to NECO; no telephone requests or hard copies will be honored. Interested organizations may email their capabilities and qualifications to the listed contact.
