E-8C takes off with new engines

The U.S. Air Force E-8C Joint Surveillance Target Attack Radar System (Joint STARS) test bed aircraft took to the air Saturday, powered by new Pratt & Whitney JT-8D-219 engines. This flight marks the start of Northrop Grumman Corporation`s  E-8C-specific military air worthiness certification test program, which will last into next spring.
Northrop Grumman is the prime contractor for the Joint STARS, a modified commercial aircraft that detects, locates, classifies, tracks and targets hostile ground movements, communicating real-time information through secure data links.
Joint STARS uses a sophisticated radar system that can scan an entire region and then send the data to a computer which analyzes movement and alerts reconnaissance specialists of any suspicious activity in near-real time. Operators onboard the aircraft can provide ground and air commanders with command and control, intelligence, surveillance, and reconnaissance information on ground-based enemy activities from hundreds of miles away.
With the ability to see vehicle movement around the clock and in any weather conditions, the system provides invaluable information to ground and air commanders that allow friendly forces to delay, disrupt and destroy their enemy.
The reliability, fuel efficiency and increased operational effectiveness inherent in the engine upgrade translates to increased Joint STARS availability to the warfighter and decreased costs. Replacing all of the engines in the Joint STARS fleet will pay for itself through the reduced operation and maintenance costs of the current engines.
The new engines can also provide added power generation for future upgrades to the radar sensor and mission equipment. A recent Air Force study indicated the fleet could stay in service beyond 2050 because of the investment made when the airframes were refurbished during production.
The engine upgrade program is based on the Propulsion Pod System incorporating Pratt & Whitney`s commercially-proven JT-8D-219 jet engine and Seven Q Seven pylons, thrust reversers, and instrumentation.
