The Department of Defense, through the Department of the Navy's NAVSUP Weapon Systems Support, is seeking proposals for the procurement of a flight-critical control interface item, identified by NSN 0R-5895-017163763-RQ and reference number 540244-120, with a quantity of one unit required. This procurement necessitates 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 successful vendor must provide comprehensive documentation as outlined in the NAVSUP WSS Source Approval Information Brochures, and failure to submit the required data will result in disqualification from the award process. Interested parties should contact Kathryn S. Hull at (215) 697-6646 or via email at KATHRYN.HULL@NAVY.MIL for further details and to ensure compliance with submission requirements.
