The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of circuit card assemblies, identified by NSN 7H-5998-013913396. The requirement includes a quantity of four units, with delivery to the DLA Distribution facility in New Cumberland, PA. These assemblies are critical components within electrical and electronic systems, and the government has determined that it is uneconomical to purchase the data or rights necessary for competitive sourcing, thus opting for a sole-source procurement approach. Interested parties are encouraged to express their interest and capability to meet the requirement within 45 days of this notice, and should direct inquiries to Leigh E. Catchings at (717) 605-2864 or via email at leigh.catchings@navy.mil.
