The Department of Defense, through the NAVSUP Weapon Systems Support, is seeking a qualified contractor for a sole-source requirement to repair nine Critical Safety Item (CSI) Radiators (NSN: 161501290317, Part Number: 111669-000). The procurement is essential for restoring government-owned articles to operational condition, as the government lacks sufficient data to contract with other sources, necessitating that unapproved sources submit detailed information for approval. The contract will be awarded under a Firm Fixed Price arrangement, with specific compliance requirements including ISO 9001 quality standards and adherence to military preservation and packaging instructions. Interested parties must contact Lauren Phillips at lauren.n.phillips6.civ@us.navy.mil for further information, and the lead time for delivery is set at 180 calendar days from the date of award.
