Quantum Systems

No single sensor works everywhere at sea. Optics and radar stop at the waterline, radio dies metres below it, and sound carries for miles without revealing its origin. So we split the work. Subvex listens with sonar and hydrophones to 6,000 m, sharing tracks over acoustic modems. Seavex watches the surface for 60 days and collects Subvex data at sea. Twister covers the air. MOSAIC UXS puts all three on one map. A noise below becomes a track a commander can act on.

Going to sea was the decision. Connecting it to air and land was the work. Last night at Sesimbra, on the sidelines of an international naval exercise, Quantum Systems introduced Seavex and Subvex. Both run on MOSAIC UXS, the same architecture already flying and driving. "The real step forward is not adding another domain. It is connecting them." — Florian Seibel, Co-CEO and Founder Air, land, surface, seabed. One operational picture.

Two thirds of the planet has never appeared in our mission logs. That changes on 14 September. We built our authority in the air, combat mission by combat mission, then extended it to the ground. One operational picture, one network. The sea was always the missing domain: distances measured in days, a medium that swallows radio signals metres below the surface, missions running above and below that surface at once. Air. Land. And from 14 September, the sea.

Threats do not stop at the waterline. Shipping keeps supply chains moving, offshore assets keep energy flowing and subsea cables carry the data underneath both. Europe treated all three as background infrastructure for decades. Recent incidents corrected that, and exposed two gaps at once: nobody can watch a domain this size continuously, and almost nobody can prove what happened once it has been hit. There are simply not enough frigates, submarines or patrol aircraft to secure this vast, open and increasingly vulnerable domain. So we are taking our capabilities to sea. The new chapter begins 14 September 2026. The future is unmanned. It now runs across air, land and sea.

For decades, reach came with an address. Runways, launchers, a base to fly home to. Depth was something you bought with infrastructure. Reliant is our long-range VTOL UAS. It lifts off vertically, crosses 160 km into contested airspace with or without GNSS, holds there past hour ten, and comes home to the same patch of ground it left. Reach like that used to start with an airfield. Reliant starts with a clearing.

Ten by ten metres of unprepared ground. That is the whole footprint Reliant needs to launch and recover. No runway, no launcher, no fixed base. Two vehicles carry the system: one for command and control, one for transport. Every stop becomes an airfield. Persistence has always been bought with infrastructure. More than ten hours in contested airspace meant a prepared strip and a coordinate that stays on the map long enough to be found. Reliant keeps the clock and leaves nothing on the map.
