The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking to procure 11 units of a specialized antenna, part number 186A993-4, from Lockheed Martin Corporation on a sole source basis. This procurement is critical as the government does not possess the necessary data or rights to source this item from alternative suppliers, emphasizing the unique capabilities of Lockheed Martin in fulfilling this requirement. Interested parties are invited to submit capability statements or proposals within 45 days of this notice, although the procurement will proceed with Lockheed Martin as the anticipated sole provider. For further inquiries, interested organizations can contact Kate N. Schalck at (215) 697-1020 or via email at kate.n.schalck.civ@us.navy.mil.
