EW Deficit: US Compass Call Fails to Blind Iran
The massive U.S. and Israeli military buildup in the Middle East has encountered a significant technical obstacle. Highly classified reports delivered to the congressional "Gang of Eight" reveal that the U.S. Air Force’s premier electronic warfare (EW) asset, the EC-130H Compass Call, and its next-generation successor, the EA-37B, are struggling to suppress Iran's integrated air defense networks. This unexpected jamming deficit has created a major hurdle for air campaign planners, contributing to the hesitation discussed in Classified Briefing: Congress Warned on Iran War.
The Compass Call Doctrine: Silent Suppression
The EC-130H Compass Call is a strategic weapon designed to disrupt enemy communications, radar, and GPS-guided systems without firing a single kinetic round. Historically, it served as a key asset in U.S. air operations:
- Venezuela & Syria: Jammed early warning radars, allowing strike aircraft to enter protected airspace.
- Libya: Suppressed Muammar Gaddafi's military communications and intercepted calls to coordinate rebel movements.
- Lebanon: Linked by intelligence reports to the pager and walkie-talkie communication disruptions.
- Airborne Cyber Attacks: The platform can inject malicious code directly into wireless networks to disable air defense systems (SEAD - Suppression of Enemy Air Defenses).
However, during recent operations near the Strait of Hormuz, the Compass Call has faced unexpected difficulties.
The Iranian Electronic Defense
Western planners are realizing that Iran’s communication networks are highly resilient to standard U.S. jamming protocols. Iran's military communications and ballistic missile guidance systems have been designed to operate outside standard GPS networks. By bypassing GPS, Iran’s missile forces successfully hit their target zones during recent live-fire maneuvers supervised by the Madinah Command, despite the presence of U.S. EW platforms.
Furthermore, Iran's advanced early warning radar networks (which include the Chinese-supplied radar networks analyzed in The Dragon's Eye: Chinese Radar Neutralizes US Stealth) have proven highly resistant to U.S. jamming.
Deployments and Vulnerable Bases
The U.S. has expanded its electronic warfare fleet in the Gulf by 100%, deploying a total of four EC-130H aircraft and the newly arrived EA-37B. These EW assets are operating out of two primary hubs:
- Ali Al Salem Air Base (Kuwait)
- Al Dhafra Air Base (UAE)
Because they host these critical EW assets, Ali Al Salem and Al Dhafra are prime targets for Iranian retaliatory strikes. In late January 2026, the first operational EA-37B (based on the Gulfstream G550 platform, previously designated EC-37B) landed at Ramstein Air Base in Germany before transitioning directly to the Gulf.
The failure to blind Iran's air defenses has delayed preemptive strike plans. U.S. planners recognize that without complete electronic suppression, a strike would not surprise Iran. The early warning systems would remain active, allowing Iran to launch its hypersonic missile swarm (detailed in Greek Report: Iran Preps 670 Hypersonic Missiles) instantly.
