The United States Air Force is preparing to replace its aging fleet of Boeing VC-25As, which have served as the primary aircraft for presidential transport, commonly known as Air Force One. These planes, based on the Boeing 747-200B and delivered in 1990 and 1991, are now over 35 years old. Their advanced age has led to increased maintenance costs and reliability issues. Parts for these older models are becoming more expensive, and the aircraft are less fuel-efficient compared to newer options.
To address these challenges, the Air Force is converting two Boeing 747-8s into VC-25Bs. The 747-8 is the largest American-built airliner and was chosen due to requirements that called for a four-engine aircraft. According to information provided, “Air Force One is not actually an aircraft, but rather the callsign of any Air Force aircraft carrying the US president.” The current VC-25As feature advanced defensive systems such as anti-missile defenses and shielded wiring.
The new VC-25Bs were originally intended for a Russian airline that went out of business before taking delivery. These jets were selected in 2017 and sent to Boeing’s San Antonio facility in 2019 for modification. However, the program has faced significant delays and cost overruns exceeding $2.8 billion beyond the original $3.9 billion budget. Much of this difficulty comes from removing existing wiring and installing new systems specific to presidential needs.
Despite setbacks, the first VC-25B is expected to be delivered by mid-2028. The new model will offer better fuel efficiency, longer range, greater passenger capacity, and improved defensive technologies—though details remain classified. Unlike their predecessors, these planes will not be equipped for aerial refueling.
The selection of the Boeing 747-8 was driven by operational requirements; only a large quadjet could meet security needs without compromise. While other options like a modified Airbus A380 were considered impractical due to production constraints outside the U.S., the 747-8 remained as the sole viable candidate.
Due to delays with the VC-25B program, an interim solution emerged: a Boeing 747-8 BBJ previously owned by Qatar’s government was transferred to U.S. control as a temporary measure. It is being modified for presidential use but may only serve missions with lower security risks or domestic flights.

“Air Force One is intended as more than just transport for the US president,” one section notes regarding its unique capabilities. “The president’s quarters…are contained entirely within the VC-25A’s nose…the VC-25A is designed as more of a flying White House.”
Another related statement emphasizes security: “Air Force One and the Doomsday aircraft are both designed as Presidential transports and command centers (for times of peace and emergencies).”
