**Ukraine's Drone Edge at Risk, Warns UK Defense Chief**

Ukraine possesses the world's most advanced battlefield drone technology. But a top British defense official warns this lead is temporary. The UK's Chief of the Defence Staff, Admiral Sir Tony Radakin, stated that Ukraine's experience in its war with Russia has made it a global leader in drone warfare. This includes both cheap, disposable drones and more complex systems. However, he stressed that other nations are learning quickly. Ukraine has a narrow "window" to export its knowledge and technology before others catch up. Admiral Radakin explained that Ukraine's advantage comes from real-world testing. Its drones are not just prototypes; they are proven in combat. This makes them valuable to many militaries. The warning highlights a critical challenge for Ukraine. Success now depends not only on using this technology but also on selling it abroad before the opportunity closes.
