The Department of Defense, through the NAVSUP Weapon Systems Support office, is seeking qualified sources for the procurement of tactical replacement parts, specifically NSN 7R-1680-016471322-RQ, with a quantity of three units required for delivery FOB origin. 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 solicited. Interested vendors must provide comprehensive documentation as outlined in the NAVSUP Source Approval Information Brochures, and failure to submit the required data 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.HULL@NAVY.MIL.
