| Swarm Aero | Swarm Aero is an aerospace and defense company that develops large-scale unmanned aerial vehicle (UAV) swarms to operate in coordinated drone swarms for defense, logistics, and sensing missions. The company builds large uncrewed aircraft and supporting software that allow multiple drones to collaborate and perform tasks as a coordinated networkrather than as independent vehicles. These systems use onboard computing, sensors, and artificial intelligence to enable autonomous flight behaviors and collective decision-making among groups of drones. The technology platform includes aircraft hardware, swarm coordination software, and command-and-control tools that allow operators to deploy and manage large numbers of drones. A swarm node architecture integrates edge computing and distributed sensors on each vehicle so that drones can communicate with one another, share environmental data, and adapt their behavior during missions. Through this system, operators can translate mission objectives into coordinated flight patterns and task assignments executed by the swarm.Swarm Aero’s aircraft and software systems support applications such as intelligence gathering, environmental monitoring, cargo delivery, communications relay, disaster response, and security operations. The platform is designed to enable operations in environments where communications may be limited or conditions change rapidly, allowing autonomous drones to coordinate actions and adjust routes in real time. | $35M | Series A | Mar 11, 2026 |  |
