UK to conduct large-scale war resilience exercise next year

The United Kingdom will conduct a large‑scale military exercise next year that, according to a senior defence minister, will be the biggest on the country’s scale “not seen for a very long time.” The exercise is scheduled to take place in the spring of 2025 and will bring together the Royal Navy, the Army and the Royal Air Force in a coordinated drill that is intended to test the nation’s overall preparedness for a range of potential threats.

The drill will simulate a complex, multi‑domain scenario that includes conventional, cyber and nuclear elements. It will involve more than 10,000 personnel, a fleet of naval vessels, aircraft, and land forces operating across several key locations, including the North Sea and the English Channel. The minister highlighted that the exercise will assess command and control, logistics, and the ability of the armed forces to respond rapidly to emerging crises, thereby identifying any gaps in capability or coordination.

By staging such an extensive test, the UK signals its commitment to maintaining robust defence readiness and to reassuring allies of its capability to respond to evolving security challenges. The exercise will be followed by a comprehensive review of performance and lessons learned, which will inform future training and procurement decisions.
