The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of 63 units of a flight-critical generator, identified by NSN 7R-6115-016270932-QE and reference number FH30001G4. This procurement is unique as it requires Government source approval prior to contract award due to the critical nature of the item and the lack of adequate technical data for competitive solicitation. Interested vendors must provide detailed information as outlined in the NAVSUP WSS Source Approval Information Brochures, and proposals must be submitted within 45 days of this notice, with the primary contact for inquiries being Michael J. Zuccarini at (215) 697-1106 or via email at MICHAEL.ZUCCARINI@NAVY.MIL.
