LMT Defence tests communications and cybersecurity capabilities at NATO CWIX 2026, supporting National Armed Forces

LMT Defence technology experts took part in NATO’s Coalition Warrior Interoperability Exercise 2026, contributing to one of the Alliance’s most significant annual events for testing and validating digital interoperability, communications and command-and-control capabilities.

CWIX 2026 took place from 8 to 26 June at the NATO Joint Force Training Centre in Bydgoszcz, Poland. According to NATO, this year’s exercise brought together more than 4,000 participants from more than 40 NATO and partner nations, making it the largest CWIX exercise to date.

The exercise provides a controlled environment where NATO, member states, partner nations and industry representatives can test whether different digital systems, networks and command-and-control solutions can work together effectively before they are needed in real operations. This is especially important in modern defence environments, where the ability to exchange trusted information quickly and securely can directly affect decision-making and operational readiness.

Latvia was represented at CWIX 2026 by 15 specialists from several National Armed Forces units, including the NAF Communications School, Headquarters Battalion, Mechanised Infantry Brigade, Air Force Air Defence Division and Joint Headquarters. LMT Defence also contributed to the Latvian contingent as a technology partner, with five company representatives supporting the development and testing of communications and cybersecurity system solutions.

During the exercise, participants worked across more than 20 focus areas. Latvia was actively involved in three of them: Federated Mission Network (FMN) and C2 scenarios, radio communications and 5G interoperability testing, and cybersecurity scenarios involving challenges such as network attacks.

“For LMT Defence, participation in CWIX 2026 is a valuable opportunity to apply our expertise in advanced communications, tactical 5G applications and cybersecurity within a multinational defence innovation environment. By working alongside military specialists and allied partners, we are able to test interoperable capabilities under demanding, operational conditions.” –  Salvis Skladovs, Director of LMT Defence.

The exercise also reflects the growing importance of secure, resilient and interoperable communication systems in national and allied defence. As NATO continues its digital transformation, cooperation between defence institutions and technology companies plays an increasingly important role in ensuring that advanced capabilities can be connected, tested and used effectively across borders.

CWIX has been hosted by NATO’s Joint Force Training Centre since 2011 and remains one of the Alliance’s key annual platforms for improving digital interoperability. The 2026 exercise included more than 600 tested capabilities and over 30,000 tests, helping NATO and partner nations strengthen readiness for future crisis and operational scenarios.
