A universal reaction among the Department of Defense when talking about their mission. fight and win on any battlefield, today and tomorrow. Boeing has adopted this mission with a program of aggressive modernization of one of the most recognizable and tested combat pieces in the U.S. Army inventory the AH-64 Apache attack helicopter. Modernization of the Apache represents a paradigm shift in helicopter warfare, making this aircraft a force to be reckoned with in multi-domain operations (MDO).
The foundation of this modernization program is a package of upgrades designed to double the Apache’s range and increase its duration. Central to this program is the addition of a new engine, the General Electric Aerospace T901, made possible by Boeing’s 2019 contract award under the U.S. Army’s Improved Turbine Engine Program (ITEP). This engine not only will be more fuel-efficient but will also offer a substantial power increase. With these engine improvements come alterations in the tail rotor and fuselage of the helicopter, which, in combination, result in a dramatic 20% boost to range. The end result is an Apache that can fly 135 nautical miles to the fight, spend about one hour on station, and come home an impressive doubling of the endurance contained in the existing E-model configuration.
In addition, the updated Apache has higher payload capacity, supporting 3,400 to 4,400 pounds of bombs, such as the airborne long-range precision munitions and possible future directed energy weapon system integration. Notably, the updated version is accompanied by the possibility of two extra pylons, bringing the number to six, thereby augmenting the helicopter’s weapons loadout capabilities.
From the perspective of connectivity and integration into the network, the AH-64E is the most network-intensive aircraft in the U.S. Army inventory, and the only aircraft that performs integrated Manned-Unmanned Teaming (MUM-T) for both lethal and intelligence, surveillance, and reconnaissance (ISR) effects. The updated Apache with autonomous launch and in-flight digital connection capabilities, positioning it as the center of the MDO battlefield. It is intended to move fast, talk fast, shoot from distance, and last during mass combat to secure the kill chain to establish decision superiority and common situational awareness.
Survivability improvements are likewise inherent in the upgraded Apache without loss of reach or safety for its aircrews. A Modular Open Systems Architecture (MOSA) is integrated, enabling future integration of emergent technologies and capabilities. It is a design that makes the Apache increasingly capable and robust over time, staying combat credible against changing threats. In the meantime, the latest production version of the AH-64E Apache, Version 6.5 (V6.5), made its initial flight at Mesa, Arizona, on October 11, 2023.
