The Department of Defense, specifically the Department of the Navy, is seeking to procure nine units of the FIELD FOX 50GHZ, identified by NSN 7G-6625-016533139. This procurement is for supplies that the Government intends to solicit and negotiate with only one source due to the lack of ownership of the necessary data for alternative sourcing, making it uneconomical to reverse engineer the part. The FIELD FOX 50GHZ is crucial for electrical and electronic properties measuring and testing, which plays a significant role in various defense applications. Interested parties are encouraged to express their interest and capability to meet the requirement within 45 days of this notice, with contact details for inquiries provided by James E. Lewis at NAVSUP Weapon Systems Support, reachable via email at JAMES.E.LEWIS5@NAVY.MIL.
