NCI Agency participates in NATO's largest and most complex computer-based exercise


From 9 to 20 October 2023, Exercise Steadfast Jupiter tested the Alliance's proficiency and readiness to respond to threats on land, at sea, in the air, in space or in cyberspace.


Steadfast Jupiter is NATO's most ambitious, complex and largest computer-based exercise, designed to train and evaluate 24 different NATO Command and Force Structure Headquarters. The exercise took place in 27 different locations across Europe and North America, and saw the participation of nearly 7,000 civilian and military personnel from 17 NATO and partner countries.

The exercise provided an excellent opportunity to test NATO's responsiveness, command and control, and defence posture in a highly challenging multi-threat environment. It also demonstrated NATO's capability and readiness to defend the Alliance and train NATO's warfighting skillsets, using a multi-domain, multi-joint operational area scenario based on an Article 5 crisis simulation.

The NCI Agency supported the exercise from eight different locations through its CIS Support Units (CSUs). The Agency's CSUs provide onsite support to NATO and NATO countries to ensure all communication networks remain operational and secure. For Steadfast Jupiter 2023, Agency experts provided participants with support from Belgium, Germany, Italy, the Netherlands, Norway, the United Kingdom and the United States.

Moreover, nearly 100 NCI Agency service matter experts provided dedicated support from the Agency's headquarters in The Hague, the Netherlands and Mons and Braine l'Alleud, Belgium.

Sponsored by Supreme Headquarters Allied Powers Europe (SHAPE) and directed by the Joint Warfare Centre (JWC), this exercise is designed to reinforce NATO's deterrence and defence posture, providing a unique opportunity to demonstrate the Alliance's commitment to the principle of collective defence.
