The contract to build the ACCS was based on 1990s specifications and awarded to the Air Command Systems International (ACSI) consortium in November 1999. Since 2000, the ACSI has been a part of ThalesRaytheonSystems (TRS). The contract provided the development and testing of the ACCS system core software is now completed. The hardware and software system has been accepted by NATO. Italy is the first nation using ACCS for limited Military Air Operations since April 2015. Germany, France and Belgium has not yet transited to ACCS, as validation nations, leaving 17 other nations still pending.
Fundamental issues with the system design have delayed the implementation by more than 15 years.
The Integrated System Support of the ACCS system, if operational, will be provided by the NATO Communications and Information Agency (NCIA) supported by in-house System Support Center (SSC).
