STAVANGER, Norway – Nearly 7,000 military and civilian personnel from NATO and partner countries will participate in STEADFAST JUPITER 2023 (STJU23), NATO’s largest computer-assisted/command post exercise (CAX/CPX), which will take place at 27 locations across Europe and North America.
Sponsored by Supreme Headquarters Allied Powers Europe (SHAPE) and directed by the Joint Warfare Centre (JWC), Exercise STEADFAST JUPITER 2023 (STJU23) 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.
STJU23 is the most ambitious NATO CAX/CPX to date in terms of both exercise complexity and the number of participating NATO Command and Force Structure Headquarters.
The defensive exercise involves 24 training audiences from strategic to the tactical levels of warfighting, including SHAPE as a strategic warfighting headquarters and the NATO Response Force 2024 (NRF24).
STEADFAST JUPITER 2023 will strengthen low- and high-intensity warfighting skillsets of the NATO Command and Force Structure Headquarters, using a multi-domain, multi joint operational area scenario based on an Article 5 crisis.
It will test the ability of Allied Joint Force Command Brunssum (JFC Brunssum), as the primary training audience, to deliver multi-domain effects through the seamless integration of air, land, sea, cyberspace, and space capabilities.
STEADFAST JUPITER 2023 will prepare JFC Brunssum for their NRF leadership in 2024, and help refine ongoing planning for next year’s major NATO exercise STEADFAST DEFENDER 2024.
Nearly 7,000 military and civilian personnel from NATO and partner countries will participate in STEADFAST JUPITER 2023, NATO’s
most ambitious CAX/CPX, which will take place at 27 locations

“STEADFAST JUPITER 2023 is decidedly aligned to the new era of collective defence, focusing on NATO’s 360-degree security approach
in all domains to maintain the very highest level of readiness.”

Training for the New Era of Collective Defence
Major General Piotr Malinowski, Commander JWC, said: “With STEADFAST JUPITER 2023, our great Alliance will be better geared towards meeting its objectives established in the Concept for Deterrence and Defence of the Euro-Atlantic Area. Conducted at four levels, including the strategic and operational levels as well as the tactical and second-tactical levels, STEADFAST JUPITER 2023 is decidedly aligned to the new era of collective defence, focusing on NATO’s 360-degree security approach in all domains to maintain the very highest level of readiness.”
The Commander added: “It’s a great honour for the JWC to direct NATO’s largest warfighting CPX just before celebrating its 20th anniversary in Norway.”
Dubbed “Deter and Defend”, the Concept for Deterrence and Defence of the Euro-Atlantic Area (DDA) is a clear demonstration of Alliance cohesion, capability and resolve in response to a myriad of complex security challenges.
It underscores a harmonized military planning network for NATO’s 31 member nations, improving intelligence sharing, surveillance activities and a shared understanding of threats across the Alliance.
STEADFAST JUPITER 2023 enables an unprecedented level of interoperability between different NATO commands and headquarters, allowing them to train together and test a wide range of capabilities and new concepts such as the multi-domain operations concept: the integration of land, air, maritime, cyberspace and space to achieve orchestrated effects.
The exercise will strengthen NATO command-and-control (C2) during an Article 5 crisis based on a highly realistic but fictional scenario created by the JWC, including simulation media, opposing forces and political constructs.
Lieutenant Colonel Michael, the JWC’s lead planner for the exercise, explained that the planning for the exercise started in November 2021.
“The exercise planning process for STEADFAST JUPITER 2023 has required constant revision and adaptation to meet the evolving demands of the multiple training audiences and real world events,” he said.
“I am genuinely awestruck by all internal and external stakeholders’ willingness for pragmatic compromise, timely decision making and sheer hard work in ensuring we have set the conditions for the JWC’s success in delivering the most challenging and complex exercise in scale and ambition. The experience has been demanding and rewarding in equal measures and will leave a legacy of understanding that will help situate the JWC for the future.”
