Satellites for Missile Defense Pass Key Review, Production to Commence
COLORADO SPRINGS – A critical design review has been successfully completed for eight satellites developed by Millennium Space Systems, featuring sensor payloads from L3Harris Technologies. This milestone clears the path for production and a projected launch in late 2027, the companies announced on April 7. These advanced spacecraft are intended for missile defense operations.
Millennium Space, headquartered in El Segundo, California, is developing these satellites under a $414 million contract granted last year by the Space Development Agency (SDA). The project, known as “Foo Fighter” – short for Fire-control On Orbit-support to the Warfighter – is a key component of the SDA’s Proliferated Warfighter Space Architecture.
These spacecraft are slated to become integral to the Space Development Agency’s Proliferated Warfighter Space Architecture, a vast network of low-Earth orbit satellites designed to deliver persistent tracking, targeting, and communications support for United States military operations.
Transition to Production Phase
“The successful completion of this design review signifies the program’s transition to the production phase,” stated Tony Gingiss, CEO of Millennium Space Systems, a Boeing subsidiary. The company aims to deliver the eight-satellite constellation alongside a ground system in 2026 and will manage mission operations following orbital deployment.
In a recent interview, Gingiss described the design review milestone for the Foo Fighter program as “a significant waypoint for us to demonstrate successful execution.” He acknowledged ongoing challenges, particularly within the production phase, emphasizing that further work remains.
Gingiss noted that producing eight satellites of this sophistication constitutes a “substantial undertaking.” He clarified that while categorized as small satellites, “these are quite sizable vehicles.” Millennium Space is constructing a new 17,000 square-foot facility on the Boeing campus to accommodate the program’s demands.
Advanced Missile Defense Capabilities
Fire Control Sensors for Precision Tracking
The Foo Fighter satellites are specifically engineered to detect and accurately track advanced missile threats, including hypersonic weapons known for their maneuverability and unpredictable flight trajectories.
A key feature of these satellites lies in their “fire control quality sensors.” This specialized equipment is designed to provide the precise targeting data necessary for intercepting sophisticated missiles.
L3Harris stated that “the sensors are capable of high-fidelity tracking of targets and delivering exact coordinates to weapon systems on the ground.” This level of precision is intended to enhance the success rate of missile intercepts, a critical objective for U.S. defense planners.
L3Harris Expands Production Capacity
L3Harris also announced the successful completion of a production readiness review for its infrared sensor payloads. The company will manufacture these vital components at its Wilmington, Massachusetts, facility, supported by a recent $10 million investment to expand production capacity.
Infrastructure Upgrades and Future Demand
Charles Clarkson, vice president and general manager of L3Harris’ space superiority and imaging division, mentioned an additional $200 million investment to further increase capacity and upgrade infrastructure at their facilities in Fort Wayne, Indiana, and Palm Bay, Florida.
Clarkson explained that these investments are in anticipation of future orders for missile warning and defense sensors, driven by the Department of Defense’s prioritization of countering advanced missile threats from near-peer competitors.
The Foo Fighter program is expected to play a central role in the “Golden Dome” initiative, a project initiated by the Trump administration to bolster U.S. defenses against next-generation missile systems. Although still in its nascent stages, Golden Dome serves as a guiding framework for integrating space-based tracking and interception into the nation’s broader missile defense architecture.
