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.

Reported restrictions capping Starlink terminals to operating speeds under 100 miles per hour leave ground systems operational while immobilizing fast-moving unmanned aircraft. Ukrainian forces depend on commercial satellite links for both kamikaze and deep-strike drones, making velocity caps a crippling battlefield constraint.

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.

To test its "F-16 for space" interceptors without real targets, True Anomaly either launches its own practice targets or performs "rendezvous and proximity operations" with existing objects in orbit. This method for gaining reps in space was originally developed by NASA in the 1950s to prepare for the Apollo missions.

Most satellites operate on highly predictable orbital paths, allowing adversaries to anticipate their movements and hide assets (e.g., covering them with tarps). Portal Space Systems is developing highly maneuverable spacecraft—'fighter jets for orbit'—to eliminate this predictability, providing a significant strategic advantage for defense and intelligence operations.

The perception of space as a peaceful frontier is outdated. It is now a critical, contested military domain where nations are actively developing capabilities to disable enemy satellites. Assured access to space is as fundamental to national security as having a traditional army, navy, or air force.

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.

As satellite density in low-Earth orbit increases, we approach a catastrophic threshold. A single collision could create a debris field that causes a chain reaction, destroying all other satellites. This "Kessler Syndrome" would cripple global communications and GPS, and could make future space launches impossible.

Ukraine is pioneering 'last mile autonomy' not as a strategic push for automation, but as a tactical necessity. When Russia jams the data link to a drone, the system can autonomously complete the final leg of its attack on a pre-identified target, countering electronic warfare.
