Story summary

In the South China Sea, the Japanese oil tanker Towa Maru navigates disputed waters under surveillance from a Chinese geosynchronous orbit synthetic aperture radar satellite.
The vessel is comparable in size to an aircraft carrier, illustrating the scale of China’s monitoring capability.
This technology could enable continuous surveillance of maritime targets, including U.S. naval fleets, with just three satellites, far less than the hundreds or thousands other nations would need.
