3 satellites to track all? Chinese radar images confirm US military fears
A Chinese satellite successfully tracked a Japanese oil tanker in the South China Sea, demonstrating a potential breakthrough in global surveillance capabilities. Radar images captured from 35,800 km away suggest that China could achieve continuous, all-weather reconnaissance of high-value targets worldwide with just three satellites.

Briefing Summary

A Chinese satellite successfully tracked a Japanese oil tanker in the South China Sea, demonstrating a potential breakthrough in global surveillance capabilities. Radar images captured from 35,800 km away suggest that China could achieve continuous, all-weather reconnaissance of high-value targets worldwide with just three satellites. This capability would allow China to monitor targets such as US naval fleets. The development raises concerns as other nations may require a significantly larger number of satellites to match China's surveillance capacity. The location of the tanker was off the northern boundary of the Spratly Islands.
