The base was created in 2010 when Andrews Air Force Base merged with Naval Air Facility Washington. It is situated in Prince George's County, Maryland, making it one of the closest military bases to the nation's capital.

Air Force One and Presidential Aircraft
Joint Base Andrews is famous as the home of Air Force One, the official airplane of the President of the United States. Currently, Air Force One consists of two specially modified Boeing 747 aircraft. The base also houses other government transport planes used by Cabinet members and Congress members. These aircraft are maintained and operated by highly trained military personnel.

These include pilots, mechanics, security personnel, and administrative staff. Joint Base Andrews works closely with other government agencies to ensure the safety and security of all flights, especially those carrying the President.
