Ukraine’s Massive New Underwater Drone: Sea Trident ST-1000

Ukraine’s Global Mark has just unveiled its first-ever Extra-Large Uncrewed Underwater Vehicle (XLUUV) at the Eurosatory 2026 defense exhibition in Paris: the Sea Trident ST-1000.

=====================

Known previously for their aerial drones and powerful electronic warfare (EW) systems, Global Mark is taking things below the surface. This steel-hulled, oval-shaped underwater beast is built for heavy-duty strikes, logistics, and neutralizing enemy underwater threats—and it’s small enough to fit inside a standard ISO shipping container for rapid road transport.

According to Global Mark, Sea Trident is an autonomous underwater vehicle designed for long range missions in maritime environments capable or delivering payloads of up to 1,000 kg to strategic targets. The system is tailored for modern asymmetric maritime operations requiring low observability and full autonomy. Low detectability and subsurface movement capability at depths up to 5 meters support covert ingress to contested maritime areas. The UUV is designed as a multi-role platform capable of performing three primary mission profiles:
1- Kamikaze / Strike operations
2- Logistics and payload delivery
3- Interception and neutralization of other UUVs

Sea Trident ST-1000 Specifications:

Length: 10 meters
Beam: 2 meters
Height: 1.5 meters (excluding mast assembly)
Weight: 10 tonnes
Range: 2,000 nautical miles
Speed: 6 knots cruising / 10 knots max
Operating Depth: 60 meters
Payload (Warhead): 1,000 kg
