The Department of Defense, through the Department of the Navy's NAVSUP Weapon Systems Support, 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, which limits competition to previously approved sources only. Interested vendors must provide comprehensive technical data and documentation as outlined in the NAVSUP Source Approval Information Brochures, and 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.
