US presidents have travelled in Boeings since 1943 but John F. Kennedy was the first to fly in a purpose-built aircraft, a Boeing 707. The current fleet is made up of 747-200B series aircraft that first came into service in 1990.
The US Air Force announced in January 2015 that these would be replaced with two 747-8s, with $2.87 billion set aside for the project between now and 2021, according to budget documents.
