European Military Leaders Call for Defence Overhaul as Security Threats Evolve

Senior European military officials have called for a major transformation of the continent’s defence capabilities, warning that modern warfare is changing rapidly and that Europe must be prepared to respond to emerging threats, including those posed by Russia.

Speaking at a defence conference in London hosted by the Royal United Services Institute (RUSI), NATO’s Deputy Supreme Allied Commander Europe, Air Chief Marshal Sir Johnny Stringer, said European allies need to rethink how they equip and organize their armed forces for future conflicts.

Stringer stressed the importance of investing in large quantities of affordable and rapidly produced military equipment, including drones and interceptor systems, rather than relying primarily on expensive platforms that require years to manufacture.

He said future military readiness would depend on a combination of mass production, precision-strike capabilities, electromagnetic warfare and stronger air defence networks capable of countering threats over long distances.

“The threat we face is at 360 degrees,” Stringer told military officials and defence industry representatives attending the conference.

He noted that NATO members must pay closer attention to northern regions and be prepared to address challenges posed by Russia’s long-range aviation capabilities and naval forces, particularly those associated with the Northern Fleet.

The comments come as several European officials have warned that Russia could rebuild significant military capabilities within the coming years. Concerns over regional security have intensified following the war in Ukraine and continuing instability in other parts of the world.

The debate also reflects growing pressure on European governments to strengthen their own defence capabilities. The administration of US President Donald Trump has repeatedly argued that European allies should assume greater responsibility for their security and increase military spending. Washington announced plans earlier this year to withdraw 5,000 troops from Germany, while Trump has previously questioned the future role of the United States within NATO.

Military leaders at the conference said recent conflicts have highlighted the need to modernize defence strategies and adapt to rapidly changing battlefield conditions.

Lieutenant General Christian Freuding, commander of the German Army, said modern warfare is undergoing a fundamental transformation. He argued that governments must not only increase defence budgets but also accelerate procurement and adopt new approaches to combat operations.

Freuding said Germany is prioritizing readily available equipment to address urgent capability gaps instead of waiting years for long-term procurement projects to be completed.

Artificial intelligence was also identified as a key factor shaping future military operations. British Army Chief of the General Staff General Sir Roly Walker said AI is dramatically reducing the time needed to process battlefield information and make operational decisions.

According to Walker, tasks that previously required days of planning can now be completed in hours, allowing commanders to respond more quickly and manage a far greater number of targets.

With a NATO summit scheduled for July in Ankara, defence officials said Europe faces increasing pressure to modernize its armed forces and prepare for a security environment that is becoming more complex and unpredictable.
