My Lords, I declare my interest as a serving member of the Armed Forces. The noble Lord, Lord West, makes an interesting point, but it also exposes a slightly uncomfortable truth: we are using multi-million-pound missiles to defeat drones which are a fraction of the cost. This is ultimately unsustainable. What is the plan? Are we going to learn lessons from Ukraine, where there is a rather more layered approach to defeating drones? Ultimately, are we going to find some other way of defeating these weapon systems?
