The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support MECH, is seeking to procure 13 units of a specific transducer, identified by NSN 1H-6695-010937842. This procurement is critical as the government does not possess the data or rights necessary to purchase or contract repair of this part from alternative sources, making it uneconomical to reverse engineer. Interested parties are encouraged to express their interest and capability to meet the requirement, with proposals being accepted within 45 days of this presolicitation notice. For further inquiries, potential vendors can contact Catherine Tran at (717) 605-6805 or via email at UYENCATHERINE.H.TRAN.CIV@US.NAVY.MIL.
