E-8 Joint STARS

E-8 Joint STARS is a United States Air Force airborne battle management and command and control platform. Its primary mission is to provide theater ground and air commanders with ground surveillance to support attack operations and target development. The system is based on the Boeing 707-300 airframe and is operated by the Georgia Air National Guard at Robins Air Force Base.

Development and history

The origins of the program trace to the Cold War requirement to monitor Warsaw Pact armored formations across the Inner German border. This led to the United States Army's Standoff Target Acquisition System (SOTAS) and the United States Air Force's Pave Mover program. Following the B-1 bomber cancellation in 1977, funds were redirected to develop an airborne radar system. The Defense Acquisition Board merged the efforts into the Joint STARS program in 1982. The Gulf War provided a critical test for two prototype E-8A aircraft, which demonstrated significant capability in tracking Iraqi Army Scud launchers and vehicle convoys during Operation Desert Storm. This success led to a decision for full-scale production, with the first operational E-8C model delivered in 1996.

Design and capabilities

The aircraft is a modified Boeing 707-300 equipped with a prominent Northrop Grumman AN/APY-7 synthetic aperture radar/moving target indicator (SAR/MTI) system housed in a 26-foot radome under the forward fuselage. The radar can scan over 19,000 square miles and distinguish between stationary and moving targets at ranges exceeding 150 miles, providing a comprehensive common operational picture of the battlefield. The mission crew, operating from workstations in the main cabin, uses this data for battle management, directing close air support, interdiction, and reconnaissance assets. The system can communicate via Link 16, satellite communications, and UHF to share data with ground stations like the Common Ground Station and units from the United States Army and United States Marine Corps.

Operational history

Following its initial operational capability in 1996, the E-8C has been deployed to virtually every major U.S. military operation. It played a pivotal role during Operation Allied Force over Kosovo, providing intelligence, surveillance, and reconnaissance (ISR) that aided in the destruction of Serbian armored units. During the War in Afghanistan and the Iraq War, Joint STARS crews tracked insurgent movements, supported counter-insurgency operations, and provided improvised explosive device (IED) detection support. The fleet has also been used for homeland security missions and disaster response, such as assessing damage after Hurricane Katrina. Ongoing operations continue in U.S. Central Command's area of responsibility.

Variants and upgrades

The two prototype systems were designated E-8A, based on former Eastern Air Lines 707-323C airframes. The sole production variant is the E-8C, which features improved mission avionics and uses re-manufactured ex-commercial 707-300 series aircraft. A significant upgrade program, the Block 20/30/40 modernization, aimed to replace aging avionics and mission computing systems to maintain relevance. However, due to high costs and airframe fatigue issues, the Department of Defense has shifted focus to the E-7 Wedgetail as the eventual replacement. Plans for a Recapitalization program using business jet airframes were ultimately cancelled.

Operators

* United States: The United States Air Force is the sole operator. All E-8C aircraft are assigned to the 116th Air Control Wing of the Georgia Air National Guard at Robins Air Force Base, operating under the Air Combat Command for tasking. The Northrop Grumman corporation provides contractor logistics support for the fleet.
