The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of 9 units of a flight-critical control panel (NSN 7R-6110-014884684-KB). This procurement is subject to Government source approval prior to contract award, as the technical data necessary for full and open competition is not available, making it uneconomical to reverse engineer the part. Interested vendors must provide detailed documentation demonstrating their capability to produce the item or submit a request for source approval, as offers lacking the required data will not be considered. Proposals must be submitted within 45 days of this presolicitation notice, and interested parties can contact Chad M. Fichter at (215) 697-2782 or via email at CHAD.FICHTER@NAVY.MIL for further information.
