The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking to procure two units of a Turning Device, Shaft, under a presolicitation notice. The procurement is for a specific National Stock Number (NSN 7H-2010-010875406) and is intended to be negotiated with a single source due to the government's determination that it is uneconomical to purchase the data or rights necessary for competitive bidding. This component is critical for ship and boat propulsion systems, highlighting 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 the notice, with contact directed to James E. Lewis at the provided email and phone number for further inquiries.
