This swarm of flying, sailing, diving drones is a military first. Not everyone is happy about it

The swarm took over land, air, water and above-water environments, but was operated as one autonomously controlled unit from a single ground station. An autonomous swarm of six drones flew in the sky, dived underwater and crept over land to assist armed forces with various experimental missions in a first-of-its-kind exercise for the UK Royal Marines. The uncrewed systems were deployed as part of training raids on simulated adversary positions in Cumbria and Dorset, and were tasked with various missions ranging from reconnaissance operations through delivering supplies to soldiers, to identifying and tracking targets of interest. Made up of six different types of drones, the swarm took over land, air, water and above-water environments, but was operated as one autonomously controlled unit from a single ground station. This means that the systems worked together, sharing data from their sensors across a single communications network.
