The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is soliciting proposals for the procurement of new manufacture spare parts, specifically a Pump and Motor Assembly. This requirement is classified as a sole source procurement, 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 are critical for military operations, and interested vendors must submit the necessary documentation as outlined in the NAVSUP WSS Source Approval Brochure, which can be accessed online. Proposals must remain valid for a minimum of 120 days following submission, and inquiries can be directed to Katlyn Galetto at Katlyn.G.Galetto.civ@us.navy.mil or by phone at 215-697-6549.
