Compass Call
Compass Call refers to a specialized U.S. Air Force aircraft designed to jam enemy communications and radar systems, disrupting their ability to coordinate actions during military operations. It acts like an invisible barrier, preventing enemies from talking to each other effectively.

TECHNICAL DEFINITION
Compass Call is the designation for the EC-130H airborne tactical electronic attack (EA) platform, derived from the C-130 Hercules, operated by the U.S. Air Force to conduct standoff communication jamming and electronic warfare against adversary command, control, communications, computers, intelligence, surveillance, and reconnaissance (C4ISR) systems.
BACKGROUND
The EA-37B Compass Call is an electronic warfare aircraft based on the Gulfstream G550 entering service with the United States Air Force with the first example delivered on 23 August 2024 to Davis–Monthan Air Force Base for crew training. The plane is replacing the EC-130H Compass Call.
