Drones have come of age in Ukraine, ruling the battlefield and overtaking artillery as the leading cause of casualties.

Kate and Mike are joined by RAF veteran Dr Keith Dear to explain how small devices once designed for consumers are now not only flying spies, but also lethal weapons that have radically changed the way land battles are fought.

And the founder of SYOS aerospace, which will supply £30m worth of drones to Ukraine, explains how drone-boat technology is evolving and has helped Ukraine neutralise Russia’s black sea fleet.
