Nearly four years into the conflict in Ukraine, the world has learned something important: mega-constellations in space are now central to keeping communication alive during war. These giant groups of satellites continue working even when electronic attacks and physical strikes happen on the ground. Their nonstop service has made them a major part of modern military operations.
Rising Alarm As Mega-Constellations Become Vital To Warfare
China has been watching these developments very closely. Recent research from Chinese universities—summarised in a widely shared report—looked deeply into how mega-constellations like Starlink work and whether they can be blocked during a conflict. The study focused on the big question many governments are now asking: Can these massive satellite networks be jammed?
The researchers say that, in theory, it is possible to interfere with them. However, doing so would require enormous effort. According to the study, disrupting Starlink over an area the size of Taiwan would take 1,000 to 2,000 drones carrying electronic jammers. This shows how strong and resilient these mega-constellations are because they include thousands of fast-moving satellites that constantly shift positions.

The findings also highlight how satellite communication systems have become some of the first targets in any major conflict, especially one involving China and Taiwan. Modern militaries rely heavily on these networks, not only for communication but also for navigation, coordination, and support. This makes mega-constellations extremely valuable but also attractive targets.
How Mega-Constellations Shape Communication And Modern Conflict
Mega-constellations support much more than military missions. They help provide internet access, guide aircraft and ships, support emergency teams, and keep systems running during disasters. Because of this, they are now seen as powerful tools that can affect both civilian life and battlefield operations.
This importance is also why they are frequently targeted. Jamming, spoofing, and cyberattacks near conflict zones have become more common. Some navigation systems have been tricked into showing wrong positions, while cyber intrusions have attempted to take control of satellite orientation. These actions are disruptive but carry less danger than firing missiles at space objects.
Experts describe these methods as “gray-zone” activities, meaning they allow countries to test or weaken rivals without starting direct conflict. With thousands of satellites working together, mega-constellations are much harder to shut down than older systems. If one satellite fails, others quickly cover the gap. This built-in resistance forces adversaries to search for new ways to interfere.

OneWeb, used by Taiwan for backup communication, and Starlink, with nearly 9,000 satellites, are major examples of how mega-constellations create strong and flexible networks. Their size and design make them difficult targets, which is why some researchers are exploring advanced ideas such as drone swarms or distributed jamming systems.
Electronic attacks and cyber tools are becoming preferred methods because traditional weapons are not effective against thousands of satellites moving across the sky. This shift shows how the rise of mega-constellations is reshaping military planning around the world.
A Growing Space Competition
China is not only studying how to disrupt mega-constellations—it is also building its own. This approach mirrors what several powerful nations are doing: strengthening defensive satellite systems while researching offensive space tactics at the same time.
Russia, China, and the United States have also tested anti-satellite weapons, showing how important space-based infrastructure has become. These tests have not been used against another country’s spacecraft, but they signal increasing interest in controlling space communication networks.
As militaries reorganise their communication and surveillance systems around mega-constellations, these networks are turning into some of the most critical assets in global security. They support troops, protect communication lines, and keep vital civilian networks running during crises.
With more jamming incidents, cyberattacks, drone interference ideas, and satellite-testing activities happening worldwide, the competition around mega-constellations continues to grow. The research discussed in the recent report is a reminder that these giant satellite systems will remain at the centre of attention for any country preparing for modern conflict.
