The Department of Defense, through the Department of the Navy's NAVSUP Weapon Systems Support, is soliciting proposals for the procurement of Preload Assembly components. This is a sole source requirement, indicating that the government lacks sufficient data to contract with any source other than the current supplier, necessitating Government Source Approval prior to award. The items are critical for maintaining operational readiness and are categorized under the NAICS code 336413, which pertains to Other Aircraft Parts and Auxiliary Equipment Manufacturing. Interested vendors must submit the required documentation as outlined in the NAVSUP WSS Source Approval Brochure, available online, and direct any inquiries to Casey Brown at casey.m.brown20.civ@us.navy.mil or by phone at 215-697-3752.
