The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking to procure four units of a specific plug pipe as part of a presolicitation notice. The procurement involves the National Stock Number (NSN) 7H-4730-015305621, and the government has determined that it is uneconomical to purchase the data or rights necessary for competitive sourcing, thus intending to negotiate with only one source under FAR 6.302-1. This part is critical for military applications, and interested parties are encouraged to express their capabilities to meet the requirement within 45 days of the notice publication. For further inquiries, potential vendors can contact Andrea Rhone at (717) 605-1125 or via email at ANDREA.RHONE@NAVY.MIL.
