The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking to procure three units of a Coil Assembly (NSN 1H-4130-016230423-PP) as part of a presolicitation notice. The procurement is limited to a single source due to the government's determination that it is uneconomical to acquire the data or rights necessary for competitive bidding, and the contract will be awarded based on the qualifications of the offeror at the time of award. This Coil Assembly is critical for refrigeration and air conditioning applications within military operations, and interested parties are encouraged to express their interest and capability to meet the requirement within 45 days of the notice publication. For further inquiries, potential bidders can contact Melissa A. Furness at (771) 229-0075 or via email at melissa.furness@navy.mil.
