The United States Air Force, created in 1947 as the Department of the Air Force under the National Security Act, was once part of the U.S. Army. Originally known as the Aeronautical Division, they later became the Air Service in 1918, changing again to the U.S. Army Air Corps in 1926, and finally, before separating, were called the U.S. Army Air Force. 

Since its inception, America’s Air Force has always been the most powerful air power in the world, with a total of 5,209 active aircraft as of today, of which many older aircraft are found. (These are the largest air forces in the world.) The Air Force is currently working to replace planes such as the B-2 Spirit with the Northrop Grumman-developed B-21 Raider, but there are still plenty of aircraft that are defying time and remain in service.

24/7 Wall St. reviewed 2022 USAF & USSF Almanac: Equipment, published in Air and Space Forces Magazine to determine the U.S. Air Force’s oldest aircraft. We excluded aircraft used as trainers. All information is from the almanac. All of the aircraft on this list are at least 34 years old. Seven of the 10 oldest planes are intelligence, surveillance, and reconnaissance/battle management/command, control, and communications aircraft and all are at least 57 years old. These plane types account for about half of the 30 oldest Air Force planes in service. (Also see, the most expensive planes in the U.S. Air Force.)

Other categories represented among the oldest aircraft in the Air Force inventory are transport planes and fighter/attack jets. The latter category includes the A-10C Thunderbolt II, with 141 planes in active service, the most on the list. The second-most on the list is the KC-135R Stratotanker with 138 aircraft. The venerable B-52H Stratofortress is the second-oldest plane on the list at 59.80 years. There are 58 B-52Hs in active service for the Air Force.
