The Department of Defense, specifically the Department of the Navy, is seeking to procure 308 units of a magnetometer under the presolicitation notice titled "59--MAGNETOMETER,OUTBOA." The procurement is for a specific part identified by NSN 1H-5930-016443687, and the government intends to negotiate with EMS Development Corp as the sole source due to the unavailability of data rights for competitive procurement. This magnetometer is crucial for various defense applications, and the government has determined that it is uneconomical to reverse engineer the part or purchase data rights. Interested parties have 45 days from the publication date to express their interest and capabilities, with inquiries directed to Tonya L. Nearhood at (717) 605-1649 or via email at tonya.nearhood1@navy.mil.
