The Republic of Korea Air Force (ROKAF) has received the first of the six F100-229 engine enhancement package (EEP) engines for installation on the air force’s F-15 aircraft.

The F100-PW-229 EEP engine, the latest evolution of the F100 fighter aircraft engines, has been funded and qualified by the US Air Force to 6,000-cycle capability.

The EEP engine developed by Pratt & Whitney increases the engine depot inspection interval from seven years to ten years, providing up to a 30% life-cycle cost reduction over the life of the engine.

With a predicted 25% reduction in the in-flight shutdown rate, the EEP will offer safety benefits.

The propulsion system, equipped with latest technologies, provides advanced power for F-15 and F-16 fighter aircraft around the world.

The firm will deliver the remaining EEP engines through 2009 and 2010 as part of the $200m engine programme, which also includes the ongoing delivery of engine build kits that will be assembled by Samsung Techwin in Korea.
