The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support MECH, is seeking to procure 167 units of the MODULE INDICATOR, identified by NSN 7H-6680-014941991-PP. This procurement is for a specific part that the Government has determined cannot be economically sourced from multiple vendors due to the lack of data rights and the impracticality of reverse engineering. The MODULE INDICATOR is crucial for measuring liquid and gas flow, liquid levels, and mechanical motion, which are essential functions in various defense applications. Interested parties must respond within 45 days of this presolicitation notice, and all inquiries should be directed to Lamar R. Crummel at (717) 605-6474 or via email at LAMAR.CRUMMEL@NAVY.MIL.
