Description
The United States Air Force is conducting market research (Sources Sought) to identify potential suppliers for new‑manufacture spares of a mechanical transmission (NSN 1680‑011‑427‑636 RK, Part Number NF53300‑03A) used on the B‑1B bomber. The effort is a “new spares buy” with an estimated requirement of 45 units (minimum 11, maximum 68). Suppliers would be expected to provide full‑scale manufacturing capability, including procurement of component parts, inspection, testing, preservation/packaging, logistics, and delivery to Tinker Air Force Base, Oklahoma. The solicitation is not a formal contract request; no funds are presently allocated, and the Government seeks information to decide whether the requirement will be competitive or set‑aside for small businesses. Interested parties must submit a Source Approval Request (SAR) package electronically via DoD SAFE and indicate interest through the “Add Me to Interested Vendors” button. No award date or contract value is specified at this stage.
