Advanced Hawkeye

The Advanced Hawkeye (PE 0604234N) program is a critical Navy Research, Development, Test & Evaluation (RDT&E) effort focused on the E-2D Advanced Hawkeye (AHE) platform. The primary objective of this program is to maintain and enhance the U.S. Navy's carrier-based airborne command and control capabilities through continuous modernization of the E-2D's mission systems, sensors, communications, and computing infrastructure. The E-2D AHE is a core component of theater and carrier strike group air defense, providing advanced radar surveillance, battle management, and enabling Joint All Domain Command and Control (JADC2) operations.

E-2D Adv Hawkeye (Project 3051) is the central line item within this program element, supporting a range of system development and demonstration activities. Key goals include upgrading the aircraft's computing architecture to support future JADC2 requirements, integrating new mission systems, and ensuring the platform remains effective against evolving peer adversary threats. The program is structured around incremental Delta System/Software Configuration (DSSC) builds, which package and deliver new capabilities to the fleet on a regular basis to maintain configuration control and commonality.

Major ongoing initiatives under this line include the Hawkeye Cockpit Technical Refresh (HECTR) and Theater Combat Identification (TCID). HECTR addresses obsolescence and safety issues in the cockpit, improving human-machine interface, reliability, and reducing lifecycle sustainment costs. TCID upgrades the mission computer and display architecture, introducing multi-level security and cross-domain solutions via an Open Mission System (OMS) architecture. These efforts are scheduled for delivery in DSSC-6, with critical design reviews and integration activities planned through FY2026.

Additional objectives include enhancements to the E-2D's air vehicle, such as structural improvements, aerial refueling capability expansion, and fatigue testing, to improve safety, reliability, and operational endurance. The program also funds continuous mission systems improvements, including avionics, navigation, data fusion, electronic support measures (ESM), and counter-electronic attack (CEA) capabilities. These upgrades ensure the E-2D can operate effectively in contested electromagnetic environments and support the Navy's Integrated Air and Missile Defense (IAMD) strategy.

Integration, test, and training activities are another major focus, with investments in developmental and operational testing, cybersecurity, and advanced training systems. The program supports the E-2D Systems Test and Evaluation Lab (ESTEL) and the development of Live Virtual Constructive (LVC) training environments, enabling the fleet to train with the latest capabilities and tactics. These efforts are essential for validating new system configurations and preparing aircrews for evolving mission requirements.

Congressional Adds provide targeted funding for advanced radar development and enhancements to the E-2D's L-band and UHF capabilities. These investments are intended to ensure the APY-9 radar system continues to meet detection, tracking, and velocity requirements in the face of emerging threats. The Congressional Adds also support research with industry and academic partners to accelerate radar technology improvements and maintain the E-2D's tactical advantage.
