The Navy intends to procure 10 units of NSN 1R-1560-017021750-LU, a wrist item, through a sole-source contract to CENTROID INC, the Original Equipment Manufacturer and only known source. The government does not own the technical data or rights needed to purchase from other sources, and a Source Approval Request (SAR) is required for any non-approved firm, though the procurement will not be delayed for SAR approval. This acquisition will follow FAR Part 15 procedures and is not a commercial item purchase or a small business set-aside. Other responsible sources may express interest and submit a capability statement or proposal, which will be considered for potential competitive procurement. The solicitation will be posted electronically via NECO, and communication must be directed to the government point of contact by email.
