While it maintains the familiar lines of the Hercules, a common sight in the world's skies for decades now, the C-130J has been extensively re-designed. The most visible change lies in the use of two 4700 HP Rolls-Royce (Allison) AE2100D3 engines, with six-blade composite-material propellers that ensure silent running and low fuel consumption. High-performance features include an excellent rate of climb and an extended range of action thanks to the new engines. An equally important development is the avionics: the cockpit, in fact, is equipped with new digital instruments and a Head-Up Display that provides the pilot with a constant stream of data without him having to look away from the cockpit window. The C-130J is steadily becoming the standard transport aircraft in many NATO countries, Italy included.
