Defense strategies in space differ drastically by orbit. Low Earth Orbit (LEO) is protected by having so many assets (proliferation) that an enemy can't destroy them all. The vastly larger MEO and GEO require highly mobile 'bodyguard' spacecraft that can move rapidly to counter threats.

While drones get the headlines, operators on the front lines in Ukraine identified Starlink as the most critical technology. This reveals that the foundational layer for future conflict is resilient, decentralized communication, which enables all other advanced systems to function in contested environments.

A leaked Russian proposal outlines a plan to divert Starlink-equipped drones for Iranian use against US forces in the Middle East. The strategy aimed to exploit the region's lack of geofencing to cause significant disruption before SpaceX could inevitably cut off access, turning a commercial technology into a temporary, high-impact weapon.

The proliferation of satellites and drones has created a "transparent battlefield" where forces are under constant observation. This blanket of sensors makes it incredibly difficult for armies to move, concentrate forces, or achieve surprise, fundamentally changing traditional military doctrines that rely on maneuver.

The decision by Elon Musk to restrict Russian use of Starlink terminals is a significant factor in the war. It directly degrades Russia's tactical command and control, situational awareness, and ability to employ certain types of drones and unmanned ground vehicles, forcing them to adapt to less efficient communication methods.

Combat in space or on the moon will be swift and catastrophic because spaceships and habitats are inherently fragile. Due to severe mass and volume constraints, they cannot be armored effectively. The winning strategy is not to withstand a hit, but to avoid detection, targeting, and being fired upon entirely.

Starlink is considered the single most critical technology in the war, providing a resilient communication backbone that circumvents Russian electronic warfare. It enables command, control, and data streaming for nearly all of Ukraine's unmanned systems, from small reconnaissance drones to large ground and naval vehicles.

Failing to return to the moon after decades of promises and $100 billion in spending would signal to rivals that the U.S. is "broken." This perceived weakness in the strategic domain of space could embolden adversaries to challenge U.S. interests in other critical technological and geopolitical areas.

Contrary to the exploratory narrative of many space programs, China's space strategy is explicitly viewed as a geopolitical tool. Military experts within China articulate a clear goal: leveraging space capabilities to achieve strategic dominance on Earth, treating space as a crucial military and power domain.
