Boeing starts ‘Air Force One’ modifications of 747-8

Boeing has begun modifications to the first of two commercial 747-8 airliners which are to be turned into US Air Force (USAF) VC-25B aircraft.
Known by its “Air Force One” call sign when the US president flies aboard, two VC-25B are to operate as the USA’s top executive transports for the next 30 years. Modifications are being done at Boeing’s San Antonio, Texas facility, says the USAF.
“The first phase of aircraft modification involves cutting out large skin and structure areas in both the forward and aft lower lobes of the aircraft and then installing two newly manufactured superpanels,” says the service. “The superpanels contain structural upgrades and cutouts for the VC-25B lower lobe doors, including internal airstairs for mission requirements.”
The USAF is working to replace its current fleet of presidential aircraft, two 747-200-based VC-25A aircraft delivered in 1991, with two 747-8s originally built for Russian carrier Transaero, which filed for bankruptcy in 2015 before it could take delivery. The commercial airliners need extensive retrofits to be transformed into the VC-25B configuration.
