ACCS is the NATOAir Command and Control System project, planned to replace the NATO Air Command and Control Systems of the nineties. At the highest level it comprised the Combined Air Operations Centre (CAOC) from which the air battle is run. Beneath this level of command is the Air Control Centre (ACC), Recognized Air Picture (RAP) Production Centre (RPC) and Sensor Fusion Post (SFP) combined in one entity called ARS. The ARS is the equivalent to the Control and Reporting Centers (CRCs) operated in the nineties. The ACCS project comprised both static and deployable elements. Under separate funding, NATO intended to procure deployable sensors for the deployable ACCS component (DAC).
Oversight of the project is provided by the NATO Communications and Information Agency (NCIA) in Brussels, Belgium (until 2012 executed by the NATO ACCS Management Organisation (NACMA) Board of Directors, senior representatives of the Nations engaged in the NATO ACCS project. The Board is responsible to the Secretary General of NATO for the delivery of the project. The NCIA AIRC2 PO&S is responsible for the day-to-day management of the project scientific support from former NC3A (now part of the NCIA), system and software engineering support from Systems Support Center (SSC) (as well part of the NCIA), logistic support from former NAMSA (again part of the NCIA) and operational support from SHAPE.
The contract to build ACCS was based on nineties specifications and awarded to the Air Command Systems International (ACSI) consortium in November 1999. Since 2000 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 its Military Air Operations since April 2015. Germany, France and Belgium will be transitioning to ACCS, as validation nations, followed by 17 other nations.
NATO principal procurement agency asked TRS to provide additional capability related to missile defence. First capability is already operational in Ramstein (Germany).
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).
