The Japanese Air Force One and Japanese Air Force Two are the radio callsigns of the two Boeing 777-300ER aircraft used by the government of Japan for overseas travel by the Emperor, Prime Minister and other high-ranking officials. Each aircraft has a capacity of 140 passengers and can be used for emergency evacuations of Japanese citizens and overseas deployment of Japan Self-Defense Forces personnel.[1] The aircraft are operated by the Japan Air Self-Defense Force.
The aircraft are officially referred to as Japanese government exclusive aircraft (日本国政府専用機, Nippon-koku seifu sen'yōki). They have the radio callsigns Japanese Air Force One and Japanese Air Force Two when operating on official business, and Cygnus One and Cygnus Two when operating outside of official business (e.g., on training flights).[2] The two aircraft always fly together on government missions, with one serving as the primary transport and the other serving as a backup with maintenance personnel on board.[3] The aircraft use the General Electric GE90-115B.
The Boeing 777-300ER replaced the original Boeing 747-400 aircraft in early 2019.[4]
