The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the repair and modification of circuit card assemblies. The procurement involves a total quantity of nine circuit card assemblies, identified by NSN 7H-7050-015383579, which must be delivered to designated distribution centers in Pennsylvania and California. These assemblies are critical components for military applications, and the government has determined that it is uneconomical to acquire the data or rights necessary for competitive procurement, thus opting for a sole-source solicitation. Interested parties are encouraged to express their interest and capabilities to the contracting officer, Kelsey Gring, via email at KELSEY.GRING@NAVY.MIL, with a response deadline of 45 days from the notice publication date.
