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 fire control system, identified by NSN 7R-6350-015773503-QE, with a quantity of 19 units required. This procurement is critical as the item is flight critical, necessitating government source approval prior to contract award, and only previously approved sources will be considered for solicitation. Interested vendors must provide comprehensive documentation as outlined in the NAVSUP WSS Source Approval Information Brochures, and failure to submit the required data will result in disqualification from the award process. For inquiries, interested parties can contact Timika Nicholson at (215) 697-2582 or via email at TIMIKA.NICHOLSON@NAVY.MIL.
