In this gorgeous 2015 calendar, we celebrate the United States Air Force. Formed in 1947, the United States Air Force is the most technologically advanced air force in the world and has over 330,000 active service members and 5,500 manned aircraft that operate around the world. The USAF has taken part in every major conflict since the Korean War and is currently an integral part of providing security and air superiority to the United States.
