The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the repair and modification of a critical server component identified by NSN 0R-0098-LLZ98S384-H1. The procurement involves two units, with delivery required FOB Origin, and is necessitated by the part's unstable design and marginal performance during testing, which may render it obsolete without significant modifications. Interested vendors must be approved sources or submit detailed documentation for source approval, as the item is flight critical, and the government intends to negotiate with only one source under FAR 6.302-1. Proposals must be submitted within 45 days of this notice, and interested parties can contact Jake Kucowski at JAKE.KUCOWSKI.CIV@US.NAVY.MIL for further information.
