The modernization program for the E-2D Advanced Hawkeye has passed a major development milestone, clearing the way for the delivery of the first upgraded aircraft by the end of the decade.
Block II to introduce open architecture and greater computing power
The upgrade package, known as Block II, has completed its critical design review, an assessment intended to determine whether the new system meets the program’s expected operational and technical requirements.
The modernization package includes:
- an upgraded cockpit;
- an open mission systems architecture;
- increased computing capacity;
- improved flight systems;
- reduced workload for pilots and mission crews.
The Open Mission Systems architecture is expected to simplify the replacement of obsolete components and accelerate the integration of new technologies without relying on proprietary solutions. Upgrades to the cockpit and flight systems should also improve situational awareness and allow crews to focus more effectively on complex battle-management tasks.
An airborne command and control hub
The E-2D Advanced Hawkeye is a carrier-capable tactical airborne early warning aircraft. Equipped with a large radar, it can detect approaching threats and coordinate the actions of other forces operating in the battlespace.
The Block II modernization is designed to keep the E-2D at the center of airborne command and control missions. The upgraded aircraft is expected to provide naval forces with a more resilient and capable platform for maintaining maritime dominance.
Although its primary mission involves airborne command and control, the E-2D can coordinate multiple operations at the same time, including air strikes, support for ground forces and rescue missions.
Flight testing expected to begin in 2029
Flight testing of the upgraded aircraft is scheduled to begin in fiscal year 2029. The manufacturer plans to retrofit E-2D aircraft already in service while also incorporating the Block II configuration into newly built aircraft.
The company has described the effort as the most significant upgrade since the E-2D was developed. Completion of the critical design review represents a major step forward for the teams and industrial partners involved in the program.
E-2D employed in major military operations
The aircraft recently took part in Operation Epic Fury against Iran, operating alongside a broad range of US military assets. The operation involved bombers, fighter jets, helicopters, one-way attack drones, destroyers and submarines.
US authorities had previously considered ending the Air Force’s E-7 Wedgetail program and purchasing additional E-2Ds as an interim solution. Lawmakers opposed the proposal, however, and development of the E-7 was subsequently resumed.
Japan already operates the aircraft, while France awaits its first delivery
The United States is not the only country operating the E-2D Advanced Hawkeye. Japan already uses the aircraft, while France is expected to receive its first Advanced Hawkeye in 2027.
