During the NATO exercise REPMUS in Portugal, the British companies BAE Systems and Malloy Aeronautics, as well as the American company L3 Harris, showed a T-600 drone armed with a torpedo. Earlier, the Ukrainian army also received similar drones. The T-600 electric drone is capable of carrying a payload of up to 200 kg over a range of up to 80 km and reaches speeds of up to 140 km/h. REPMUS is a Portuguese-led exercise aimed at developing unmanned technology. During the exercise, the T-600 drone dropped the Sting Ray anti-submarine torpedo for the first time. In addition to dropping torpedoes, the T-600 drone will be used to evacuate the wounded and deliver cargo to ships.
