The AH-64D Apache Longbow, is equipped with a glass cockpit and advanced sensors, the most noticeable of which being the AN/APG-78 Longbow millimeter-wave fire-control radar (FCR) target acquisition system and the Radar Frequency Interferometer (RFI), housed in a dome located above the main rotor.


The AH-64E features improved digital connectivity, the joint tactical radio system, more powerful T700-GE-701D engines with upgraded face gear transmission to accommodate more power, capability to control Unmanned aerial vehicle, full IFR capability, and improved landing gear. New composite rotor blades, which successfully completed testing in 2004, increase cruise speed, climb rate, and payload capacity.
