The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support MECH, is seeking to procure 30 units of the NSN 7H-2010-013800192, identified as the HUB AND CYLINDER AS, 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 uneconomical to acquire the data or rights necessary for competitive bidding. This component is critical for ship and boat propulsion systems, emphasizing its importance in maintaining naval operational capabilities. Interested parties are encouraged to express their interest and capability to meet the requirement within 45 days of this notice, and they may contact Alexander Craft at (717) 605-4147 or via email at ALEXANDER.CRAFT@NAVY.MIL for further details.
