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 global positioning system component, identified by NSN 0R-6605-016982856-RQ, with a quantity of three 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 this solicitation. Interested vendors must provide comprehensive technical data and documentation as outlined in the NAVSUP WSS Source Approval Information Brochures, as failure to do so will result in disqualification from the award process. For further inquiries, interested parties can contact Nadia Govorushko at (215) 697-2813 or via email at NADIA.GOVORUSHKO@NAVY.MIL.
