The 6 dumbest things I thought I knew about the military before I joined
The EC-130H Compass Call is an airborne tactical weapon system whose primary mission is to disrupt enemy command and control infrastructure, limiting adversary coordination and force management.
The aircraft is a heavily modified C-130 Hercules variant, one of the largest and longest airframes in Air Force history.
From the outside, the aircraft may look like a normal Hercules, but internally, advanced electronic warfare and electronic attack computer systems allow the Air Force to locate, listen to, and scramble. enemy communications.
The effect of non-kinetic rejection is not permanent, but it provides the desired result of blocking the enemy across the entire electromagnetic spectrum.
The effectiveness of the compass call is to create a fog of war for enemy combatants, making them easier targets for US ground forces.

The Air Force is the sole operator of the EC-130H, and the Compass Call has ensured airspace superiority during its 35-year operational life. The aircraft has demonstrated a powerful effect on enemy command and control networks in multiple military operations including Kosovo, Haiti, Panama, Libya, Iraq, Serbia and Afghanistan.
Development and design
The EC-130H made its first flight in 1981, was delivered to the Air Force in 1982, and reached initial operational capability in 1983.
The CE identifier of the aircraft signifies the special electronic transport of the installation.
A Cold War weapon, it was originally designed to suppress enemy air defenses and spent its early years overseeing air defense systems integrated under the Warsaw Pact.
The aircraft is powered by four turboprop engines and has a flight speed of 300 mph and a range of nearly 2,300 miles.
The Airborne Tactical Weapon System has undergone changes over the years, with each update providing more powerful avionics systems, radars, and more powerful digital signal analysis computers and subsystems.
The EC-130H aircraft carries a 13-person combat team. Four members are responsible for the flight and navigation of aircraft, while nine members operate and use the EA mission equipment permanently integrated in the cargo / mission compartment.

The Block 35 Baseline 1 EC-130H provides the Air Force with additional capabilities to interfere with communication, early warning / acquisition radar and navigation systems with higher effective radiated power, at extended frequency range and the insertion of digital signal processing compared to previous EC-130Hs. Basic 1 aircraft have the flexibility to keep pace with the adversary’s use of emerging technologies.
Baseline 2 has a number of upgrades to lighten the operator’s workload and improve efficiency. Improved external communications allow Compass Call teams to maintain situational awareness and connectivity in dynamic operational and tactical environments.
The delivery of Baseline-2 provides the DoD with the equivalent of a âfifth generation electronic attack capabilityâ, improving aircraft performance and survivability.
The majority of the upgrades found in the EC-130H Compass Call Baseline-2 are classified mission system modifications that improve accuracy and increase attack capabilities.
In 2017, the Air Force announced plans for a Compass Call replacement platform based on the Gulfstream 550 Airborne Early Warning aircraft. The new platform was named EC-X.
Operation and deployment
The 14 Compass Call aircraft are assigned to Air Combat Command. The 55th Electronic Combat Group made up of two operational squadrons, the 41st and 43rd Electronic Combat Squadron operate the EC-130H. The 55th ECG is a tenant unit from the 355 Fighter Wing at Davis-Monthan AFB, Ariz., Which reports to the 55th Wing at Offutt AFB, Nebraska.

The 55th ECG recently eclipsed 10,900 combat sorties and 66,500 flight hours, as it provided US and coalition forces and joint commanders with a flexible advantage across the spectrum of conflict.
Did you know
- Since its introduction in 1954, there have been 54 modified variants of the C-130
- The EC-130H was introduced in 1983 and began providing airborne attack capabilities in 1989 to support U.S. Army Rangers during Operation Just Cause in Panama.
- The EC-130H is one of America’s four major electronic warfare aircraft, along with the EA-18G Growler, EA-6B Prowler, and F-16CJ Fighting Falcon, forming the Suppression of Enemy Air Defense triad ( SEAD).
