The Department of Defense, through the NAVSUP Weapon Systems Support office, intends to modify Basic Ordering Agreement N00383-22-G-YY01 on a sole source basis with The Boeing Company to add three National Item Identification Numbers (NIINs): 014781918, 013177906, and 016250798. This procurement is specifically for spare parts and repair support, with NIIN 014781918 designated solely for spares orders, while the other two NIINs will be utilized for both spares and repairs. The goods are critical as they pertain to airframe structural components, and the Government does not possess the necessary data to procure these items from alternative sources, making Boeing the sole known provider. Interested parties may submit capability statements or proposals within 45 days of the notice, and should direct inquiries to Dylan Payne at dylan.e.payne.civ@us.navy.mil.
