NAVSUP WSS Philadelphia intends a sole-source repair procurement for one unit of NSN 7R7021016851725 (PN 266A640-530), naming Lockheed Martin as the intended source while the source-approval paragraph references Sikorsky as the anticipated single acceptable offeror. Any firm not already approved to manufacture the material must submit a Source Approval Request, and the procurement will not be delayed for SAR approval. The acquisition will use FAR Part 15 procedures rather than FAR Part 12 commercial-item policies and is not a total small business set-aside. Electronic procedures will be used and the solicitation will be posted to NECO. No telephone requests or hard copies will be honored, and interested organizations may email capabilities and qualifications to Samantha.m.freedman.civ@us.navy.mil.
