China's 510 spy satellites can monitor globe every 30 minutes

China has significantly expanded its space-based surveillance infrastructure, deploying more than 510 military reconnaissance satellites that can track global military movements with unprecedented frequency and precision. U.S. intelligence reports indicate the fleet has grown more than threefold compared to 2018 levels, representing a substantial acceleration in Beijing's space capabilities.

The satellites are part of an integrated surveillance system designed to gather intelligence beyond traditional imagery, now incorporating real-time data on adversary military activities. With the current constellation, Chinese authorities can monitor any location on Earth approximately every 30 minutes, according to assessments, providing strategic advantages in reconnaissance and early-warning capabilities.

The rapid expansion reflects China's broader modernization of its military infrastructure and growing emphasis on space-based systems for strategic intelligence gathering. Analysts note the development underscores Beijing's commitment to enhancing its space domain capabilities in competition with established powers, particularly the United States.

The constellation's growth has raised concerns among regional nations and Western powers about surveillance capabilities and space security. China's investment in reconnaissance satellites aligns with its broader strategic objectives of strengthening situational awareness across Asia and beyond, experts suggest.
