Air Force Longevity Service Award

The Air Force Longevity Service Award is a military award of the United States Air Force established 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 Air Force Longevity Service Award is awarded for completing four years of Active, Air Force Reserve, or Air National Guard service.
The Air Force Longevity Service Award is a ribbon only award. It is ultramarine blue divided by four equal stripes of turquoise. Oak leaf clusters are worn on the ribbon to indicate subsequent awards of the Air Force Longevity Service Award.
