Autonomous Systems: Land & SeaBackground
Elistair Khronos is a tethered drone system from French manufacturer Elistair, flown from Exail's DriX O-16 uncrewed surface vessel during sea trials completed on 15 July 2026, alongside a Safran VIGY 4 electro-optical/infrared camera.
Kept aloft and powered through a cable rather than an onboard battery, a tethered drone can hold station for continuous surveillance FAR longer than a free-flying quadcopter, feeding a live video and sensor link back to whatever it is anchored to. Flying Khronos from an uncrewed hull rather than a crewed ship let the DriX O-16 demonstrate over-the-horizon surveillance directed without anyone aboard, a small but concrete step in extending persistent aerial watch to autonomous maritime platforms.
