The Department of Defense, through the Department of the Navy's NAVSUP Weapon Systems Support, is soliciting proposals for the procurement of support assembly components, specifically related to airframe structural components. This requirement involves a total quantity increase from 289 to 365 units, with a focus on spare parts that necessitate Government Source Approval prior to award, as the government lacks sufficient data to contract with sources other than the current supplier. Interested vendors must provide the necessary documentation as outlined in the NAVSUP WSS Source Approval Brochure, which is available online, and should direct any inquiries to Jacob Wells at jacob.r.wells1@navy.mil or via telephone at 215-697-1227. The procurement is classified under NAICS code 336413, and the solicitation does not include a set-aside for small businesses.
