Seasats has launched a fleet of autonomous hunter ships designed to monitor and track Chinese ghost fleets. The unmanned vessels are now operational, targeting the shadowy network of fishing and cargo ships that often operate outside international law. It's a new tool in a long-running battle against illegal fishing and maritime deception.
What Ghost Fleets Are
Ghost fleets are vessels that deliberately obscure their identity, location, or cargo. They turn off transponders, spoof their registration, or transfer catch at sea to avoid detection. Chinese-linked operators have been accused of using such tactics to poach in protected waters and smuggle goods. These ships are notoriously hard to track with conventional patrol boats and satellite surveillance alone.
Seasats says its autonomous hunter ships can fill that gap. The company builds drones that operate for weeks at a time without human crew. They rely on solar and wind power to stay at sea, carrying sensors that pick up radar, radio signals, and visual data. The ships can follow a target for days, providing persistent surveillance that manned vessels can't match.
How the Hunter Ships Work
Each autonomous vessel is about the size of a small sailboat. It has no crew quarters, no galley, no bathroom. That frees up space for fuel and electronics. The design is modular, so the company can swap payloads depending on the mission. For ghost-fleet tracking, the ships carry a combination of optical cameras, AIS receivers, thermal imaging, and electronic intelligence gear.
The drones don't just record data. They process it on board using edge computing, flagging suspicious behavior in real time. That allows them to send alerts to naval authorities or environmental agencies before a target slips away. Seasats has already tested the system in several oceans, and the company's customers include government agencies focused on maritime domain awareness.
A big advantage is cost. An autonomous ship can stay on station for months with minimal support. A conventional patrol boat requires a crew, fuel, and regular port calls. The hunter ships are meant to supplement, not replace, the manned fleet. They handle the dull, dirty, and dangerous work of long-term surveillance.
A Growing Problem
Illegal fishing costs the global economy tens of billions of dollars every year. It also undermines conservation efforts and hurts legal fishers. Chinese ghost fleets have been spotted off West Africa, in the South Pacific, and near the Galápagos Islands. Some analysts suspect the same vessels are used for sanctions evasion and smuggling.
Seasats' launch comes as international pressure builds to crack down on these operations. The U.S. Coast Guard, the European Union, and several Pacific island nations have all increased patrols. But the ocean is vast, and the bad actors keep adapting. Autonomous systems offer a way to scale up monitoring without a proportional increase in personnel.
The company has not disclosed how many hunter ships it has deployed or the exact locations of their operations. It also hasn't named any customers. Those details remain unclear. What is clear is that the boats are already at work, and the ghost fleets have one more thing to watch for on the horizon.
