BAE Systems' missile detection satellites have passed an early design review for the U.S. Space Force's medium Earth orbit (MEO) sensor layer program. The satellites are specifically designed to detect and track hypersonic missiles, a growing threat that current geostationary missile warning systems struggle to monitor effectively due to their high orbital altitude and limited coverage.
The MEO constellation will operate at approximately 8,000-12,000 miles above Earth, providing better tracking geometry and reduced latency compared to traditional geostationary early warning satellites positioned at 22,236 miles altitude. The satellites will feature infrared sensors capable of detecting the heat signatures of hypersonic vehicles traveling at speeds exceeding Mach 5. Technical specifications include hardened electronics to resist space radiation and cyber attacks.
The Space Force has not disclosed specific launch dates for the BAE Systems satellites, though the MEO sensor layer is part of the broader Proliferated Warfighter Space Architecture (PWSA) scheduled for initial deployment in the mid-2020s. The program aims to create a resilient, distributed network of hundreds of small satellites across multiple orbital planes to ensure continuous global coverage.
This development represents a critical capability gap that the Pentagon is rushing to fill as China, Russia, and other nations advance their hypersonic weapons programs. The MEO sensor layer will complement existing ground-based radars and geostationary satellites, providing the persistent tracking needed for effective missile defense. The program also supports broader military space competition as adversaries develop anti-satellite capabilities.
The contract value and total program cost have not been publicly disclosed, though similar Space Force satellite programs typically range from hundreds of millions to several billion dollars over their lifecycle.
