The AH-64 Apache, the world's premier attack helicopter, was designed to be an extremely tough survivor under combat. The multi-mission AH-64D Apache Longbow is the next-generation version of original AH-64A Apache. With its fire-control radar, the aircraft is known as the AH-64D Apache Longbow. Without the radar, the combat-proven aircraft is called the AH-64D Apache (shown here).
