The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support MECH, is seeking to procure seven units of a liquid level indicator, identified by NSN 7H-6680-015688566. The procurement is based on a presolicitation notice indicating that the government intends to negotiate with only one source due to the unavailability of data or rights necessary for competitive procurement, as it has been deemed uneconomical to reverse engineer the part. This equipment is critical for measuring liquid levels in various applications, underscoring its importance in maintaining operational readiness. Interested parties are encouraged to express their interest and capabilities within 45 days of the notice, with all communications directed to Robert Langel at the provided contact details.
