The US Air Force is the world's premier aerial power.
With 39 distinct types of aircraft, and many more subvarieties of each airframe, it is easy to understand why the US Air Force has no peers. Each airframe is custom-made to carry out a select mission effectively, and each
pilot knows their aircraft perfectly.
Below are the 39 distinct types of aircraft that the US Air Force fields, according to the Air Force Fact Sheets.
