The Department of Defense, specifically the Department of the Air Force, is seeking to modify an existing sole source contract with Boeing Digital Solutions, Inc. for the Safety of Navigation (SoN) program under the IDIQ FA810120D0001. This modification aims to extend the ordering periods by adding a one-year optional ordering period and a six-month optional ordering period to accommodate the increased demand for digital access to a Federal Aviation Administration (FAA) certified aeronautical database and associated services, which are critical for ensuring the safety of flight for the U.S. Air Force and other government agencies. Interested parties may submit capability statements or proposals for consideration, and the anticipated award date for the modification is August 20, 2025.
