Exail's DriX O-16 completed sea trials flying an Elistair Khronos tethered drone and a Safran camera from a crewless hull, extending its sensor reach over the horizon.

Key takeaway

Exail proved one autonomous boat can carry a tethered drone and camera, replacing several single-purpose survey platforms.

Exail's DriX O-16 uncrewed surface vessel (USV) completed sea trials integrating an Elistair Khronos tethered drone and a Safran VIGY 4 electro-optical and infrared camera, demonstrating over-the-horizon surveillance directed from a crewless hull.⁠1 The DriX O-16 is a survey and patrol boat; the tethered aircraft, wired to the vessel for power and data, extends its sensor horizon well beyond mast height while staying tethered to the marine platform that carries it.

Third-party payload integration lets a navy bolt a chosen sensor and a chosen tethered drone onto one autonomous surface vessel rather than commissioning a purpose-built platform for each mission. In practice that shortens the path from requirement to sea trial and lets a single hull cover survey, patrol and surveillance tasks, adding to a run of European uncrewed-boat milestones days after Britain airdropped a Kraken K3 SCOUT USV from an A400M transport. The trials also fall inside the asset base Thales folds in-house through its Exail acquisition, struck the same fortnight.

Deep Analysis

In plain English

Exail's DriX O-16 is a small uncrewed boat that can sail itself. In a recent test, it carried a drone on a cable, called a tethered drone, that flew above it, plus a camera that sees in the dark, letting the boat watch much further than it could with its own sensors alone. This matters because it shows one uncrewed boat can carry sensors and drones built by other companies, rather than needing a single manufacturer to build everything into one custom vessel.

What could happen next?
  • Opportunity

    Third-party payload integration lets a navy or operator combine a chosen sensor and drone on one hull rather than commissioning a bespoke platform per mission.

After the Legislative Yuan voted 60 to 50 on 27 August for a baseline of NT$40bn a year, in principle, for domestic drones and rejected its special budget, the Cabinet said on 30 August it would expedite funding and indicated it would co-sign the act. Taipei gets a statutory domestic market but loses a ring-fenced multi-year fund.
