The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support MECH, is seeking to procure 11 units of an electron tube, identified by NSN 7H-5960-009066087. The procurement is limited to specific sources as defined by source control or selected item drawings, due to the unavailability of suitable technical data or manufacturing knowledge for alternative sources. This electron tube is critical for defense applications, and the government intends to solicit and negotiate with only one source under FAR 6.302-1, with proposals due within 45 days of the notice publication. Interested parties can contact Darian Holley at (717) 605-1339 or via email at darian.holley@navy.mil for further information.
