The Department of Defense, through the Department of the Navy's NAVSUP Weapon Systems Support, is soliciting proposals for the procurement of starter valves and other replacement parts. This requirement is classified as a sole source procurement, necessitating Government Source Approval prior to award, as the Government lacks sufficient data to contract with sources other than the current supplier. These components are critical for maintaining operational readiness and functionality within naval systems. Interested vendors must submit the necessary documentation as outlined in the NAVSUP WSS Source Approval Brochure, available online, and can direct inquiries to Kate Schalck at 215-697-1020 or via email at kate.n.schalck.civ@us.navy.mil.
