This template is used to format United States Air Force (and predecessors) aircraft serial numbers in such a way that they are not mistaken for number ranges. USAF serial numbers since 1921 consist of two numbers (fiscal year and sequence number) joined by a hyphen. This format is often mistaken for a number range by editors, and as such the hyphen is often incorrectly replaced with and en dash per MOS:RANGE, especially by automated or semi-automated editors such as AutoWikiBrowser.

The United States Army uses a slightly modified system for its aircraft serial numbers, and therefore this template can be used for US Army aircraft. This tempate should not be used for United States Navy, Marine Corps, and Coast Guard aircraft, which use entirely unrelated systems for serialization. As of 2024, the United States Space Force does not operate its own aircraft, and it is unclear as to which serialization system would be used should it acquire its own aircraft.
Additionally, some other counrties' armed forces use similar formats for aircraft serialization. This template can also be used for these militaries, and redirects have been created for some to avoid confusion:
