The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support MECH, is seeking to procure 41 units of the Transmitter Subassembly (NSN 7H-6680-015991697) under a presolicitation notice. The procurement is for supplies that the Government intends to solicit and 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 measuring liquid and gas flow, liquid level, and mechanical motion, which are essential functions in various defense applications. Interested parties are encouraged to express their interest and capability to meet the requirement within 45 days of the notice, with contact details for inquiries provided by April N. Schlusser at (717) 605-7230 or via email at APRIL.SCHLUSSER@NAVY.MIL.
