The Department of Defense, through the Department of the Navy's NAVSUP Weapon Systems Support, is seeking proposals for the repair and modification of a flight-critical item identified by NSN 7R-1680-016480499-RQ. This procurement requires government source approval prior to contract award, as the technical data available has not been deemed adequate for full and open competition, meaning only previously approved sources will be considered. The selected contractor will be responsible for delivering one unit, with delivery terms set to FOB Origin, and must provide comprehensive documentation as outlined in the NAVSUP WSS Source Approval Information Brochures to be eligible for consideration. Interested parties should contact Nadia Govorushko at (215) 697-2813 or via email at NADIA.GOVORUSHKO@NAVY.MIL for further details and to ensure compliance with submission requirements.
