The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is soliciting proposals for the procurement of components related to the Reserve System, classified under the NAICS code 336413. This opportunity is a sole source requirement, indicating that the government lacks sufficient data to contract with any source other than the current approved supplier, necessitating Government Source Approval prior to award. The components are critical for aircraft hydraulic, vacuum, and de-icing systems, emphasizing their importance in maintaining operational readiness and safety in naval aviation. Interested vendors must submit the required documentation as outlined in the NAVSUP WSS Source Approval Brochure, available online, and can direct inquiries to Casey Brown at casey.m.brown20.civ@us.navy.mil or by phone at 215-697-3752.
