The AH-64E Apache program sustains and modernizes the Apache fleet through technology insertions implemented in block configurations. The AH-64E delivers required and enhanced operational capabilities with increased “time on wing” and reduced operations and support cost.

The U.S. Army Modernization Plan calls for the Apache to remain a major weapons system in the Army's force structure until 2040 and beyond. Therefore, to maintain readiness, mission effectiveness, and operational relevance, AH-64E modernization is essential.
The Army’s plan is for 690 AH-64E Apache aircraft. In addition, a growing number of defense forces worldwide are under contract or considering upgrading to the AH-64E.

The AH-64E Apache helicopter has 26 new technologies to enhance its capabilities, including an improved drive system; a new composite main rotor blade; an increase in the hover ceiling altitude at greater gross weight; and a more powerful on-board computer system to help pilots remotely fly unmanned aircraft and streamline maintenance.
