The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support MECH, is seeking to procure 427 units of electronic tubes under the presolicitation notice titled "59--ELEC TUBE." The procurement is intended for supplies that will be solicited and negotiated with a limited number of sources, as per FAR 6.302-1, emphasizing the need for engineering source approval to maintain part quality. These electronic tubes are critical components for military applications, and the government is not utilizing FAR Part 12 for this solicitation, indicating a focus on specialized requirements rather than commercial items. Interested parties are encouraged to express their interest and capability within 15 days of this notice, and all inquiries should be directed to Randy Stoker at (717) 605-4682 or via email at RANDY.STOKER1@NAVY.MIL.
