The Air and Space Longevity Service Award (ASLSA) is a military award of the United States Air Force and United States Space Force established as the Air Force Longevity Service Award by Air Force General Order 60, on 25 November 1957 by General Thomas D. White, Air Force Chief of Staff.

The award was primarily created as an air force equivalent to the service stripes used by other branches of the United States military to denote years of military service.

The award is retroactive to the establishment of the U.S. Air Force as an independent service in September 1947.

For members of the Air Force Reserve and Air National Guard, creditable service must have been in a drilling status with regular attendance of at least minimum monthly weekend drills and annual training.

Service as a student at a United States service academy, typically the USAF Academy, is also creditable so long as the member graduated.
