The E-8C Joint Surveillance Target Attack Radar System (Joint STARS, or JSTARS) is an airborne battle management, command and control, intelligence, surveillance and reconnaissance platform. Its primary mission is to provide theater ground and air commanders with ground surveillance to support attack operations and targeting that contributes to the delay, disruption and destruction of enemy forces.
The E-8C is a modified Boeing 707-300 series commercial airframe extensively remanufactured and modified with the radar, communications, operations and control subsystems required to perform its operational mission. The most prominent external feature is the 27-foot long, canoe-shaped radome under the forward fuselage that houses the 24-foot long, side-looking phased array antenna.
The radar and computer subsystems on the E-8C can gather and display detailed battlefield information on ground forces. The information is relayed in near-real time to the Army and Marine Corps common ground stations and to other ground command, control, communications, computers and intelligence (C4I) nodes.
The antenna can be tilted to either side of the aircraft where it can develop a 120-degree field of view covering nearly 19,305 square miles and is capable of detecting targets at more than 820,000. The radar also has some limited capability to detect helicopters, rotating antennas and low, slow-moving fixed wing aircraft.
As a battle management and command and control asset, the E-8C can support the full spectrum of roles and missions from disaster relief and peacekeeping operations to major theater war.
Joint STARS evolved from Army and Air Force programs to develop, detect, locate and attack enemy armor at ranges beyond the forward area of troops. The first two developmental aircraft deployed in 1991 to Operation DESERT STORM and supported Operation JOINT ENDEAVOR in December 1995.
Joint STARS supported NATO troops over Bosnia-Herzegovina in 1996 and Operation ALLIED FORCE in 1999. Since Sept. 11, 2001, the fleet has flown more than 130,000 combat mission hours in support of operations worldwide, including Operations ENDURING FREEDOM, IRAQI FREEDOM, and INHERENT RESOLVE in support of U.S. Central Command.
Team JSTARS, consisting of the Georgia Air National Guard’s 116th Air Control Wing, the active-duty 461st Air Control Wing, and Army JSTARS detachment, provides joint airborne command and control, intelligence, surveillance and reconnaissance support over land and water to combatant commanders around the globe. The total force integration unit operates the world’s only Joint STARS weapon system based out of Robins Air Force Base, Georgia.
