The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking to procure five units of the Centrifugal FUE, identified by NSN 1R-1680-016480304-RQ and reference number 1C12-49. This procurement is critical as the item is flight critical, and the government requires source approval prior to contract award due to the lack of adequate technical data for competitive solicitation. Interested vendors must provide comprehensive documentation as outlined in the NAVSUP WSS Source Approval Information Brochures, and proposals must be submitted within 45 days of this notice, with the understanding that the government may proceed with award based on fleet support needs if necessary. For inquiries, Patrick J. Kilkenny can be contacted at (215) 697-2560 or via email at PATRICK.J.KILKENNY2.CIV@US.NAVY.MIL.
