The Department of Defense, through the NAVSUP Weapon Systems Support, is soliciting proposals for the procurement of 287 units of walking beam assemblies, classified under NAICS code 336413. This requirement is a sole source procurement, as the government lacks sufficient data to contract with any source other than the current supplier, necessitating Government Source Approval prior to award. Interested vendors must submit the required documentation as outlined in the NAVSUP WSS Source Approval Brochure, which is available online. For further inquiries, potential bidders can contact Kate Schalck at 215-697-1020 or via email at kate.n.schalck.civ@us.navy.mil.
