BYDGOSZCZ, Poland. For the last three weeks, more than 4,000 participants from 46 Allied and Partner nations gathered for Coalition Warrior Interoperability eXploration, eXperimentation, eXamination and eXercise (CWIX) 2026, hosted by NATO’s Joint Force Training Centre.

CWIX is NATO Allied Command Transformation’s premier digital interoperability event and the Alliance’s largest venue for testing, validating and improving command and control capabilities and information technology services.

Across rows of interconnected tents, engineers, operators, software developers, military planners and capability specialists from dozens of nations worked side by side, discovering opportunities and solving problems together in real time. Conversations moved seamlessly between operational challenges, technical solutions and future concepts as teams collaborated with one shared ambition – ensuring NATO forces can deploy, connect and operate together from the first day of any mission.

Testing Interoperability Before Operations Depend on It

Behind the scenes, more than 8 kilometres of fibre optic cable and 6 kilometres of copper cabling connected hundreds of national and NATO systems, creating one of the Alliance’s most sophisticated temporary digital environments. More than 30,000 interoperability tests, in 19 capability focus areas, across 27,000 square metres of dedicated testing infrastructure. Every connection created another opportunity to challenge assumptions, expose interoperability gaps and improve the ability of Allied forces to operate together.

Led by Allied Command Transformation, CWIX provides NATO and Partner Nations with a realistic operational environment where systems, data services, software applications, networks and emerging technologies are explored, experimented, examined and exercised under demanding multinational conditions.

Some capabilities performed exactly as intended. Others revealed integration challenges that could only be discovered when systems from dozens of nations were connected together. That is precisely why CWIX exists, to identify and solve interoperability issues before they affect operational missions.
