The US Air Force has announced the acquisition of two additional Boeing 747-8 aircraft for approximately $400 million. The purchase supports training and sustainment for the future presidential airlift fleet as delays continue to push back delivery of the next-generation Air Force One aircraft. The program, launched in 2018, was originally expected to deliver modified 747-8 aircraft beginning in 2024 but has been repeatedly delayed due to supply chain disruptions and workforce constraints. According to AeroTime, the Air Force currently operates two VC-25A aircraft, modified Boeing 747-200s that have been in service since the early 1990s. The newly acquired aircraft are intended to provide non-operational airframes for training and testing purposes.
