Mirai is an Italian tech company building a sovereign European autonomy and orchestration layer for unmanned systems. Navies, coast guards and offshore operators need to cover more sea with fewer people, yet every unmanned platform today comes locked to its own vendor’s software. Mirai OS breaks that lock: it runs on any hull or airframe, so fleets of surface and aerial assets plan and adapt together, node by node rather than from a single control room, while the operator keeps command at the level they choose. We prove it on our own USV, Frame Alpha, a full electric catamaran designed in house and operating at sea since 2026.
