The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of 10 units of aircraft landing gear, identified by NSN 1R-1730-008542237-SX. This procurement requires government source approval prior to contract award due to the flight-critical nature of the item, and only previously approved sources will be considered for this solicitation. Interested vendors must submit detailed technical data and documentation as outlined in the NAVSUP WSS Source Approval Information Brochures, and failure to provide the required information will result in disqualification from the award process.
