Eleven nations either fly or have selected AH-64 Apache helicopters. Nearly 1,100 Apaches, in either the AH-64A or AH-64D configuration, are in service around the world. Boeing introduced the AH-64D Apache Longbow, the newest member of the Apache family, in 1997. It features fully integrated avionics and weapons plus a state-of-the-art modem that transmits real-time, secure digitized battlefield information to air and ground forces. It can rapidly detect, classify, prioritize and engage stationary or moving opposition targets at standoff ranges in nearly all weather environments.
