The U.S. Air Force defined the standard in order to have a common computing architecture and thereby reduce the costs of software and computer systems for all military computing needs. This includes embedded tasks such as aircraft and missile control systems as well as more mundane general military computing needs.
The advantages of this concept were recognized outside of the USAF and the 1750A was adopted by numerous other organizations, such as the European Space Agency, NASA, Israeli Aircraft Industries and many projects in academia.
Examples of military aircraft using the 1750A include:
IAI Lavi fighter
IBM Federal Systems AP-102 Avionics Computer (used in various roles including the USAF F-111 avionics upgrade)
US Army AH-64D Apache Longbow Helicopter
USAF F-16 Digital Flight Control System and Fire Control Computer
USN F-18 RFCS Flight Control Computer
