The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is soliciting proposals for the procurement of an Arm Assembly, Torque, as part of a spares purchase. 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 supplier, necessitating Government Source Approval prior to award. Interested vendors must submit the necessary documentation as outlined in the NAVSUP WSS Source Approval Brochure, which is available online, to be considered for this opportunity. For inquiries, potential bidders can contact Anna M. Kiessling at 215-697-3752 or via email at ANNA.M.KIESSLING.CIV@US.NAVY.MIL.
