The Department of Defense, through the Department of the Navy's NAVSUP Weapon Systems Support, is seeking proposals for the procurement of 9 units of the flight-critical item identified by NSN 7R-1377-016098988-P8, reference number 474617-1-03. This procurement requires government source approval prior to contract award, as the technical data available does not support acquisition through full and open competition, meaning only previously approved sources will be considered. The selected supplier must provide comprehensive documentation as outlined in the NAVSUP WSS Source Approval Information Brochures, and offers lacking the necessary data will not be considered. Interested parties should contact Timika Nicholson at (215) 697-2582 or via email at TIMIKA.NICHOLSON@NAVY.MIL for further details and to ensure compliance with submission requirements.
