U.S. Space Force Expands Missile Defense and Communications to Medium-Earth Orbit Amid Evolving Threats
The U.S. military is expanding its missile defense and space communications capabilities to medium-Earth orbit (MEO), according to Col. Michael Rupp of the U.S. Space Force. This strategic shift is a direct response to the evolving threat landscape, particularly the emergence of hypersonic glide vehicles that can maneuver post-boost phase and have unpredictable trajectories. Rupp, the system program director for Resilient Missile Warning and Tracking Systems (MWT) at Delta 84, Space Systems Command, stated that the current low-Earth orbit (LEO) systems cannot keep up with these advanced threats. The Space Force is moving towards a multi-orbit architecture to effectively identify, track, and defeat adversarial hypersonic threats. MEO, which lies between 2,000 km and 20,000 km above Earth, is considered the 'Goldilocks zone' because it is high enough to be challenging to attack, yet requires fewer satellites (25 to 36) compared to the hundreds needed for LEO coverage, making it more resilient and cost-effect...
