The Department of Defense, specifically the Department of the Navy, is seeking to procure two units of the Antenna Control Unit, NSN 7G-5985-016149993, through a presolicitation notice. The procurement involves repair and modification services for this specialized equipment, which is critical for various defense applications, and the government has determined that it is uneconomical to purchase the data or rights necessary for competitive sourcing. Interested parties are encouraged to express their interest and capabilities to the contracting officer, Troy L. Cobaugh, via email at troy.cobaugh@navy.mil, within 45 days of the notice publication, as the government intends to negotiate with only one source under FAR 6.302-1.
