The Department of Defense, through the NAVSUP Weapon Systems Support office, is seeking proposals for the repair and modification of circuit card assemblies, specifically NSN 0R-5998-017256390-RQ, with a quantity of 2 each required. This procurement is critical as the items are flight critical, necessitating government source approval prior to contract award, and only previously approved sources will be considered for this solicitation. Interested vendors must provide detailed technical data and documentation as outlined in the NAVSUP Source Approval Information Brochures, as failure to do so will result in disqualification from the award process. For further inquiries, interested parties can contact Kathryn S. Hull at (215) 697-6646 or via email at KATHRYN.S.HULL.CIV@US.NAVY.MIL.
