Boeing E-8 JSTARS airplane model. The USAF E-8C Joint Surveillance Target Attack Radar System (Joint STARS) is a United States Air Force airborne battle management and command and control (C2) platform that conducts ground surveillance to develop an understanding of the enemy situation and to support attack operations and targeting that contributes to the delay, disruption and destruction of enemy forces. These functions support the primary mission of Joint STARS -- to provide dedicated support of ground and air theatre commanders.
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 12 m (40 ft) long, canoe-shaped radome under the forward fuselage that houses the 7.3 m (24 ft) long, side-looking APY-7 phased array antenna.
The E-8C can respond quickly and effectively to support worldwide military contingency operations. It is a jam-resistant system capable of operating while experiencing heavy electronic countermeasures. The E-8C can fly a mission profile for 9 hours without refueling. Its range and on-station time can be substantially increased through in-flight refueling.
