Boeing has performed the first flight of a Pratt & Whitney F100-229EEP-equipped F-15K for South Korea.
The first "Slam Eagle" from Seoul's 21-aircraft follow-on order for the type, the multirole fighter completed a debut 1h 8min test flight from St Louis, Missouri on 19 April.
South Korea's Slam Eagle order represents a powerplant shift, with its air force's in-service fleet of 39 F-15Ks using General Electric F110-129s.

Boeing delivered 40 of the aircraft between 2005 and 2008, with one having been destroyed in a fatal accident.
P&W says its enhanced engine package for the F100-229 increases the time between overhaul from 4,300 to 6,000 cycles, and will result in an up to 30% reduction in lifecycle costs. The company will also supply the new version of the engine to power Lockheed Martin F-16s on order for Morocco and Pakistan.
