Cessna Aircraft and Bell Helicopter both contributed to the design and development of parent company Textron’s new Scorpion military jet, which was unveiled yesterday. According to a Textron spokesman, Bell brought composite expertise to the project, while Cessna designed and built the jet at its Pawnee facility in Wichita. A nearly completed prototype, which has been fitted with a pair of Honeywell TFE731 turbofans, is expected to fly by year-end. Low-rate initial production is scheduled to start in 2015 at Cessna’s Wichita plant.
