The Apache Project Office (Apache PO) is gearing up for the upcoming AH-64E Version 6.5 (V6.5) upgrade that promises to enhance the capabilities of this formidable attack helicopter, ensuring its effectiveness on the modern battlefield.
The AH-64E Version 6.5 upgrade focuses on both hardware and software enhancements, reinforcing the Apache’s lethality, survivability, situational awareness, navigation, and communication capabilities. These improvements are crucial for maintaining a dominant position in combat scenarios.
One of the key highlights of the V6.5 upgrade is the inclusion of an upgraded software program. By establishing a common Operational Flight Program software baseline across the Apache E model fleet, the upgrade streamlines training and maintenance procedures while laying the groundwork for future sensor and capability advancements. This software development also aligns with the Program Executive Office, Aviation’s common configuration strategy, allowing for a more synchronized fleet operation.
In addition to the software enhancements, the V6.5 upgrade introduces an Open Systems Interface (OSI), marking a significant step towards a more open systems architecture. This development facilitates the swift integration of new technologies and enhances the Apache’s overall capability in future updates. The Apache Project Office has carefully designed these software upgrades to address Department of Defense (DOD) security mandates, Army Aviation and Army Capabilities Manager (ACM) Attack/Recon priorities, and the 2019 Version 6 Follow-on Operational Test and Evaluation findings.
While the software improvements form a substantial part of V6.5, the upgrade also involves crucial hardware insertions. This necessitates a modification work order to support the retrofit of all V4 series and V6 series Apache E-model aircraft to the V6.5 standard. The Apache PO has diligently carried out Systems Readiness Reviews and Preliminary Design Reviews, ensuring that the V6.5 upgrade progresses smoothly. The highly anticipated first flight of the V6.5-equipped Apache is scheduled for the fall of 2023.
Looking ahead, the development program for V6.5 is projected to conclude in 2025. Following this, the fielding of the upgraded version through aircraft retrofit is planned to commence in fiscal year 2026 (FY26). This timeline indicates that the AH-64E will receive additional software and hardware updates in FY25 as it integrates the Improved Turbine Engine (ITE) for Developmental Testing (DT). Successful completion of the DT will allow the Apache to support the Advanced Turbine Engine (ATE) office in the Operational Test & Evaluation for the ITE program.
Katie White, ITE Integration assistant product manager, expressed enthusiasm for integrating the more capable engine onto the AH-64E. White commended the collaborative efforts of the Apache ITE Integration team, Aviation Turbine Engines Project Office, Boeing, General Electric, and other stakeholders, highlighting their crucial role in ensuring successful integration and qualification activities.
