U.S. Space Force to Deploy New Ground-Based Satellite Jammer System

The U.S. Space Force is preparing to deploy a new ground-based jammer system designed to disrupt satellite communications of potential adversaries, including China or Russia. 

According to a Bloomberg report, the initial phase of deployment will see the installation of 11 out of a planned 24 Remote Modular Terminal jammers within the United States over the next few months. All 24 units are expected to be operational by December 31 at undisclosed locations.

Earlier this year, the Pentagon’s space service branch conducted tests of the system at two locations, with control exercised from a third site. The Remote Modular Terminals are intended to counter satellite communications from Chinese and Russian satellites without affecting U.S. satellites. The devices are described by the U.S. Space Force’s Rapid Capabilities Office as small, transportable, and low-cost, designed for deployment in austere environments to protect U.S. forces.

The jammers feature a circular antenna approximately 3 meters in diameter. The Pentagon emphasizes that the technology is defensive and specifically designed to temporarily disable, rather than destroy, adversary satellites, thereby mitigating the risk of space debris. The system uses off-the-shelf commercial components to maintain cost-effectiveness and mobility.

The new Remote Modular Terminals will complement existing U.S. satellite jammers, including the Counter Communications System and Meadowlands.
