US Navy's E-2D Advanced Hawkeye Modernization Enters New Phase

The US Navy's E-2D Advanced Hawkeye modernization program has taken a significant step forward with the completion of its Critical Design Review (CDR). The program, which aims to update the architecture of the E-2D's airborne early warning and control system, is now moving forward with physical modifications and flight testing.

## Modernization Incorporates New Architecture

The modernization program, known as Block II, is the latest evolution of the Delta 6 Software System Configuration (DSSC-6). Its primary goal is to establish a software base that enables the rapid incorporation of new capabilities. To achieve this, the Block II modernization includes a new cabin architecture and increased computing capacity. Additionally, the update incorporates an Open Mission Systems (OMS) architecture and enhanced cybersecurity measures. This configuration is designed to facilitate the integration of new technologies without relying on proprietary solutions, allowing the E-2D to address the obsolescence of current and future components.

The modernization is expected to increase the E-2D's ability to act as an airborne command and control node, while also enabling the rapid introduction of additional capabilities. Furthermore, the modernized flight systems and new cabin design will reduce pilot workload.

## Program Advances Towards Flight Testing

The PMA-231 Office of the E-2/C-2 Advanced Hawkeye Systems Program Management Office, in collaboration with Northrop Grumman, has organized a technical review to evaluate the final product baseline and associated technical elements of the Block II modernization. With the completion of the CDR, the program has formally exited the design phase and is now moving forward with physical modifications and flight testing.

The US Navy plans to initiate flight testing of the E-2D configured with Block II during the 2029 fiscal year. PMA-231 will continue to manage the program throughout its lifecycle.

## US Navy Acquires Additional E-2D Advanced Hawkeye

In July, the US Navy confirmed the acquisition of three additional E-2D Advanced Hawkeye Block II aircraft from Northrop Grumman. The contract, valued at approximately $1.2 billion, includes support services to maintain the operational readiness of the aircraft. The delivery of the new aircraft is scheduled to take place before December 2031.

The production of the new aircraft will be distributed across various facilities in the United States and other countries. The Northrop Grumman facility in Melbourne, Florida, will concentrate on up to 30% of the production process, while facilities in Aire-sur-l'Adour, France, and Wimborne Minster, UK, will participate with shares of 2.09% and 0.01%, respectively.

The completion of the CDR marks a significant milestone for the E-2D Advanced Hawkeye modernization program, paving the way for the physical modifications and flight testing scheduled to begin in 2029.
