The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is soliciting proposals for the procurement of power supply and other replacement parts. This opportunity is classified as a sole source requirement, meaning that the government does not possess sufficient data to contract with any source other than the current approved supplier, necessitating Government Source Approval prior to award. The items sought are critical for aircraft maintenance and repair, underscoring their importance in supporting military operations. Interested vendors must submit their proposals along with the required documentation as outlined in the NAVSUP WSS Source Approval Brochure, available online, and can direct inquiries to Danielle Junod at danielle.m.junod.civ@us.navy.mil. Proposals must remain valid for a minimum of 120 days following submission.
