The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking to procure two units of the PCI Express Interface (NSN 7H-5998-LLH0F3152) under a presolicitation notice. The procurement is set aside for small businesses and involves supplies for which the government intends to negotiate with only one source, as it has been determined that acquiring the necessary data or rights for competitive procurement is uneconomical. This equipment is critical for military applications, and interested parties are encouraged to express their interest and capabilities within 45 days of the notice. For further inquiries, potential bidders can contact Lamar R. Crummel at (717) 605-6474 or via email at lamar.crummel@navy.mil.
