The Navy is pushing harder toward fielding swarms of drones to accomplish missions and guard its ships. In August of last year, the service tested swarms of autonomous boats. Now, they want to take the technology into the air with drones that will fly in a coordinated swarm. To rapidly deploy the drones, the Navy is firing them from cannons.
The crown jewel of the research is the technology to coordinate the drones into a swarm, so the current drones being tested could be switched out for other platforms such as the popular Reaper and Predator drones once the technology matures.
