The Department of Defense, through the Department of the Navy's NAVSUP Weapon Systems Support, is soliciting proposals for a sole source contract to supply control boxes for aircraft, specifically under the NAICS code 336413, which pertains to Other Aircraft Parts and Auxiliary Equipment Manufacturing. The procurement is critical as the government lacks sufficient data to contract with sources other than the current approved supplier, necessitating that all proposals include the required documentation from the NAVSUP WSS Source Approval Brochure. Interested vendors must ensure they are an approved source and submit their proposals along with the necessary information to be considered for this opportunity. For inquiries, potential bidders can contact Casey Brown at 215-697-3752 or via email at casey.m.brown20.civ@us.navy.mil.
