The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is soliciting proposals for the procurement of shaft, shouldered components as part of a Foreign Military Sales (FMS) spares purchase. This procurement is classified as a sole source requirement, indicating that the government does not possess sufficient data to contract with sources other than the current supplier, and requires 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 further inquiries, potential bidders can contact Kate Schalck at 215-697-1020 or via email at kate.n.schalck.civ@us.navy.mil.
