NAVSUP WSS Philadelphia intends to solicit on a sole-source basis to Rockwell Collins a repair requirement for radio receiver-transmitters (NSN 7RH 5821014440314 V2, P/N 822-2640-001), total quantity 4. Responsible sources may submit capability statements, proposals, or quotations for consideration, but the Government intends to negotiate with limited sources under 10 USC 3204(a)(1) and FAR 13.106-1(b)(1). Source approval applies to this NSN; firms not already approved must submit a Source Approval Request, and the procurement will not be delayed for SAR approval. UID requirements do not apply for FMS requirements, Buy American clauses will apply, and this is not a Total Small Business Set-Aside. Electronic procedures will be used, no telephone requests or hard copies will be accepted, and interested organizations should email NAVSUP WSS N7 Contract Specialist Caitlin V. Donahue.
