US Space Force Jamming Systems Counter Iran Threats

Iran repeatedly targeted US space capabilities, including satellite communications terminals, to degrade American military advantages, The Wall Street Journal reported. The report said US Space Force electromagnetic systems played a crucial role in operations in Venezuela and Iran, as Guardians transported and deployed a mobile jamming system to support US military operations in both countries.

Countering threats to space systems

The Wall Street Journal gained access to a US Space Force base in Colorado, where personnel showed it Pentagon capabilities designed to disrupt enemy satellites and detect threats to US forces. One system, Meadowlands, can jam enemy satellites and disrupt their communications. Those satellites support surveillance, communications and navigation.

Meadowlands often operates alongside Bounty Hunter, a defensive system that scans the electromagnetic spectrum to detect and locate potential threats to US forces. After commanders identify a specific threat, they can order a defensive strike. The systems address threats to electromagnetic connections and satellite capabilities that the US military uses.

The report said satellites help the US detect missile launches, guide weapons and get a clear picture of the battlefield, including through high-resolution imagery taken from above. According to The Wall Street Journal, Iran repeatedly targeted US space capabilities to degrade those advantages.

A mobile jamming capability

The US Space Force has sped up deployment of a newer jamming system, the Remote Modular Terminal. Personnel can pack the system into a container and transport it around the world, so US forces can deploy electronic warfare capabilities quickly.

Over the past year, US Space Force soldiers, known as Guardians, transported and deployed Remote Modular Terminal systems to support US military operations in Venezuela and Iran. The Wall Street Journal described the system's mobility and the Guardians' deployments, but didn't provide further details about the operations or the equipment's specific effects in either country.

Tech.-Sgt. Joshua Lomax helped counter threats during operations in Venezuela before he deployed to defend against threats from Iran. He told The Wall Street Journal he had just 72 hours to pack the equipment in Venezuela, load it onto an aircraft and depart for Iran.

“The threat is real,” Lomax said. “It was incredibly intense,” he added, recalling the deployment. “Everybody was head on a swivel.”

The contest over the spectrum

Electromagnetic waves travel at different wavelengths and frequencies. They underpin many technologies used in modern warfare, the report said. The systems connect military assets ranging from submarines and drones to radar installations.

US Space Forces' Combat Forces Command, led by Lt.-Gen. Greggory Gagnon, has a key mission: dominate the electromagnetic spectrum. Gagnon described how systems that battlefield users can't see still matter to military operations.

“That thing you never see is incredibly important in warfare,” Gagnon told The Wall Street Journal. “If we can dominate the spectrum, we can keep our systems, our satellites, our ships, our planes, all connected and working more effectively, but we can also disrupt the adversary's ability to do it.”

The Jerusalem Post published its report on October 15, 2026, at 03:13, under the byline of Sarah Moskowitz. Its account drew on The Wall Street Journal's reporting from the Colorado base and its description of US Space Force systems and deployments.
