The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is soliciting proposals for the procurement of circuit card assemblies. This procurement is classified as a sole source requirement, necessitating Government Source Approval prior to award, as the Government lacks sufficient data to contract with sources other than the current supplier. The circuit card assemblies are critical components for various defense applications, underscoring their importance in maintaining operational readiness. Interested vendors must submit the required documentation as outlined in the NAVSUP WSS Source Approval Brochure, which can be accessed online, and direct any inquiries to Kate Schalck at 215-697-1020 or via email at kate.n.schalck.civ@us.navy.mil.
