The boss of BAE Systems did not mince his words. In an interview tied to the Farnborough air show, Dr Charles Woodburn delivered a blunt warning: the UK has grown too complacent about the risk of foreign attack. The threat level, he said, is the highest he has seen in his lifetime.
This is not alarmism from the sidelines. Woodburn runs Europe's biggest defence contractor. When he speaks about deterrence, taxpayers should listen. For years ministers talked about peace dividends and smaller forces. Now the bill for that complacency is coming due.
The reality on the ground has changed
Russia and Ukraine have become highly skilled at using autonomous systems. Drones and counter-drone technology dominate the battlefield in ways that were science fiction two decades ago. Woodburn pointed out that the UK must develop matching capabilities to counter these threats and deter aggression. A mix of traditional platforms such as aircraft, ships and submarines alongside unmanned systems offers the most effective path forward.
The British Army tells its own story. It has fallen from 153,000 regular soldiers in 1990 to just 74,000 today. That is not a posture built for serious deterrence. It is the result of repeated choices to cut capability while hoping others would handle the heavy lifting.
The reality of modern warfare has changed profoundly, requiring corresponding changes in UK defence spending and capabilities.
Woodburn welcomed recent increases in the defence budget but made clear they fall short. Current plans point to 2.68 percent of GDP by 2030. The long-term target sits at 3.5 percent by 2035. He believes significantly more funding will be needed to get there and to give the armed forces the equipment required for proper deterrence.
The UK is approaching the deployment of autonomous lethal weapons. It sticks to a policy of human control. Some adversaries do not. That asymmetry cannot be wished away. Deterrence demands that British forces receive the best tools available, not yesterday's kit in tomorrow's fight.
