Stand-Off Jammer
A stand-off jammer is an aircraft, ship, or vehicle that disrupts enemy radar and communications from a safe distance, outside the reach of their defensive weapons. It acts as an electronic shield, protecting friendly forces as they approach a target.

TECHNICAL DEFINITION
A Stand-Off Jammer (SOJ) is an Electronic Attack (EA) system, typically an airborne platform like the EA-18G Growler or EC-130H Compass Call, that transmits high-power radio frequency (RF) energy to disrupt, deceive, or deny enemy radar, C4I systems, and communications. Operating from a position outside the lethal range of enemy air defenses (a stand-off position), the SOJ provides area-wide electronic warfare (EW) support for penetrating strike packages and suppression of enemy air defenses (SEAD) missions.
BACKGROUND
The Kawasaki C-2 is a mid-size, twin-turbofan engine, long range, high speed military transport aircraft developed and manufactured by Kawasaki Aerospace Company. In June 2016, the C-2 formally entered service with the Japan Air Self-Defense Force (JASDF). There are ongoing efforts to sell it overseas to countries such as New Zealand and the United Arab Emirates.

USAGE NOTE
This term is distinct from a self-protection jammer, which is integrated into a specific aircraft for its own defense, as the SOJ's role is to protect a larger force or area.
DEVELOPERS
Organizations developing technology related to Stand-Off Jammer.
Prime contractor for the U.S. Navy's AN/ALQ-249 Next Generation Jammer Mid-Band (NGJ-MB), a key stand-off jammer system designed for the EA-18G Growler aircraft to disrupt and degrade enemy air defenses and communications.
Develops advanced electronic warfare systems, including the AN/ALQ-257 Integrated Viper Electronic Warfare Suite (IVEWS) and is the lead for the U.S. Navy's Next Generation Jammer Low Band (NGJ-LB) capability, focusing on disrupting early warning radars from a distance.
A major developer of airborne electronic warfare systems. They are the prime contractor for the Next Generation Jammer Low Band (NGJ-LB) pod structure and integration, and also develop advanced electronic attack systems that can be deployed in stand-off roles.
Designs and manufactures sophisticated electronic warfare systems for various aircraft. Their product line includes digital electronic warfare suites and jamming systems that provide stand-off electronic attack capabilities to protect friendly forces and deny adversary systems.
As the manufacturer of the EA-18G Growler, the premier U.S. airborne electronic attack platform, Boeing is responsible for integrating various stand-off jammer pods, including the Next Generation Jammer systems, onto the aircraft.
Develops highly integrated electronic warfare systems for advanced aircraft like the F-35, whose AN/ASQ-239 system provides sophisticated electronic attack capabilities. They also develop pod-based EW systems for stand-off jamming missions.
An Israeli defense electronics company that produces a range of airborne electronic warfare and signal intelligence systems, including pod-based self-protection and escort jamming systems like the ELL-8222 which can function as a stand-off jammer.
A Swedish company developing the Arexis family of advanced modular electronic warfare systems. These can be configured in podded solutions for fighter aircraft to provide stand-off jamming and electronic attack capabilities against modern threats.
