Lockheed Martin DREXR Upgrade Advances E-2D Hawkeye Capability
The Lockheed Martin DREXR upgrade has successfully completed flight testing on the U.S. Navy’s E-2D Advanced Hawkeye, marking an important step in keeping one of America’s most critical airborne early warning aircraft ready for future threats. The company announced the milestone on April 21, saying the program was completed in cooperation with Northrop Grumman.
The E-2D Advanced Hawkeye is the Navy’s carrier-based airborne surveillance and battle management aircraft. It provides long-range radar coverage, tracks hostile aircraft and missiles, and helps connect naval and joint forces across the battlespace.
- Lockheed Martin and Northrop Grumman completed flight testing of the DREXR upgrade for the U.S. Navy E-2D Advanced Hawkeye.
- DREXR stands for Digital Receiver Exciter Recorder and replaces legacy exciter and receiver subsystems.
- Tested capabilities included wideband transmit and receive, software-defined waveforms, and independent radar element transmission.
- Upgrade is designed to improve detection, tracking, and decision speed in contested environments.
- E-2D remains a key airborne command-and-control asset for U.S. Navy carrier strike groups.
The latest DREXR modernization effort focuses on upgrading core radar electronics rather than replacing the aircraft itself. That matters because the Hawkeye fleet remains central to U.S. carrier strike group operations, especially as potential adversaries field longer-range missiles, stealth aircraft, electronic warfare systems, and drone swarms.
What The DREXR Upgrade Changes
According to Lockheed Martin, DREXR, short for Digital Receiver Exciter Recorder, is a compact single-box system that replaces the current exciter and receiver subsystems aboard the aircraft.
During flight testing, the team validated:
- Wideband transmit and receive functions
- Independent transmit control for each radar element
- Software-defined waveform capability
- Integrated recording for mission analysis
- Data collection to support future AI-enabled capabilities
In practical terms, these upgrades should allow faster software changes, better signal processing, and improved adaptability against emerging threats.
That is increasingly important because modern radar competition is no longer only about range. It is also about how quickly a sensor can classify targets, reject jamming, and share data across multiple platforms.
Why The E-2D Hawkeye Still Matters
The E-2D Advanced Hawkeye is often overshadowed by fighter jets, but it is one of the most valuable aircraft on any carrier deck.
Its AN/APY-9 radar is designed to detect aircraft and cruise missiles at long range while supporting command-and-control functions. The platform also acts as a communications node linking ships, aircraft, and joint forces.
From an operational standpoint, fighters such as the F-35 can strike targets, but platforms like the Hawkeye help the fleet see first and react first.
That makes modernization programs like DREXR strategically significant. Improving sensing and battle management can increase the effectiveness of every other platform operating nearby.
Broader U.S. Navy Modernization Context
The DREXR milestone comes as the U.S. Navy and industry are also pursuing broader Block II modernization for the E-2D fleet, including cockpit, computing, and mission system upgrades.
This layered approach suggests the Navy intends to keep the Hawkeye relevant well into the next decade rather than rushing toward an entirely new replacement platform.
For Pentagon planners, that is a practical path. Incremental upgrades can deliver better performance faster and at lower risk than launching a clean-sheet aircraft program.
Analysis
The Lockheed Martin DREXR upgrade is more than a routine electronics refresh. It reflects a larger shift in military aviation where software speed, modular hardware, and sensor networking are becoming as important as airframe performance.
As maritime threats expand in the Indo-Pacific and other theaters, the side that detects first and coordinates faster gains a decisive edge. In that environment, the E-2D Hawkeye remains a high-value asset, and upgrades like DREXR help preserve that advantage.

E-7A Rapid Prototype Program Advances With Major USAF Contract Modification
The E-7A Rapid Prototype program received a major boost after the U.S. Air Force awarded Boeing a $2.33 billion contract modification to continue development of the next generation airborne mission system. The award expands an existing contract for the E-7A Rapid Prototype Airborne Mission Segment, bringing the program’s cumulative contract value to approximately $4.9 billion.
The work will support development of the U.S. Air Force’s future airborne battle management aircraft based on the E-7A Wedgetail platform. The aircraft is expected to replace the aging E-3 Sentry fleet, which has served as the backbone of U.S. airborne early warning and command operations for decades.
According to the U.S. Department of Defense contract announcement, work will take place primarily in Seattle, Washington, with additional efforts in Oklahoma City, Oklahoma, Huntsville, Alabama, and Heath, Ohio. The program is scheduled for completion by August 10, 2032.
The Big Picture
The E-7A Rapid Prototype program forms a central part of the U.S. Air Force’s broader effort to modernize airborne command and control capabilities.
Airborne early warning and battle management aircraft serve as critical nodes in modern military operations. They provide long range radar coverage, track airborne and maritime threats, coordinate fighter aircraft, and manage complex air campaigns across large theaters.
The current U.S. Air Force E-3 Sentry fleet entered service during the Cold War. While the aircraft has undergone several upgrades, age related maintenance challenges and evolving operational demands have increasingly strained the platform.
The E-7A Wedgetail, already operated by several U.S. allies, offers a modern replacement that integrates advanced radar, improved networking, and enhanced mission systems designed for modern multi domain warfare.
What’s Happening
The contract modification awarded to Boeing exercises an option within the existing E-7A Rapid Prototype program contract.
The $2,335,411,756 modification supports the development of the airborne mission segment that will enable the aircraft’s command and control capabilities.
The Air Force Life Cycle Management Center at Hanscom Air Force Base in Massachusetts manages the contract. The center oversees development of mission systems, sensors, and integration for several advanced U.S. Air Force programs.
Fiscal year 2026 research, development, test and evaluation funds totaling $31 million were obligated at the time of the award.
Boeing will lead development work from its facilities in Tukwila and Seattle, Washington. Additional program activity will occur in several other aerospace centers supporting systems engineering, software integration, and mission system testing.
The effort continues through 2032, reflecting the complexity of integrating advanced battle management technologies into a new operational aircraft.
Why It Matters
Modern air warfare increasingly relies on networked operations rather than standalone platforms.
Airborne early warning aircraft serve as command hubs that connect fighter aircraft, ground forces, naval assets, and intelligence systems. They allow commanders to coordinate operations across large areas while maintaining situational awareness.
The Boeing E-7A Wedgetail aircraft introduces a digitally advanced radar system capable of tracking multiple airborne targets simultaneously. The platform uses the Multi role Electronically Scanned Array radar integrated into a distinctive dorsal structure known as the “top hat.”
Compared with legacy systems, the E-7A offers improved reliability, lower maintenance demands, and enhanced sensor performance.
The aircraft also supports modern data links and distributed command networks that align with the U.S. military’s emerging Joint All Domain Command and Control architecture.
Strategic Implications
The E-7A Rapid Prototype program carries significant implications for U.S. military readiness.
Air superiority operations depend heavily on real time situational awareness and coordination. Without airborne battle management platforms, fighter aircraft would struggle to operate efficiently across large theaters.
The Indo Pacific region presents particular challenges due to its vast geographic scale. Aircraft like the E-7A enable long range surveillance and command capabilities that support distributed operations across the Pacific.
NATO operations also rely heavily on airborne warning aircraft for air policing and coalition air operations. The E-7A could eventually support alliance operations if integrated into broader NATO command networks.
Replacing aging E-3 aircraft ensures the United States retains a reliable airborne command capability as operational demands increase.
Competitor View
Strategic competitors closely track U.S. airborne command and control modernization.
China continues to expand its own airborne early warning fleet, including platforms such as the KJ-2000 and KJ-500, which support long range air operations across the Western Pacific.
Russia operates several A-50 airborne early warning aircraft, though modernization efforts have faced delays.
From a competitor perspective, the Boeing E-7A Wedgetail aircraft strengthens U.S. ability to coordinate large scale air operations and maintain situational awareness in contested airspace.
Airborne battle management systems can significantly influence the effectiveness of fighter aircraft, long range missiles, and integrated air defense networks.
What To Watch Next
Several milestones will shape the future of the E-7A Rapid Prototype program.
Upcoming phases will include mission system development, integration testing, and operational evaluation. These stages determine how effectively the aircraft integrates sensors, communications systems, and command networks.
The U.S. Air Force also plans to procure multiple E-7A aircraft in the coming years to replace its E-3 fleet.
Initial operational capability could emerge later this decade if testing proceeds on schedule.
Capability Gap
The E-7A Rapid Prototype program addresses a growing capability gap created by the aging E-3 Sentry fleet.
The E-3 aircraft face increasing maintenance costs and reduced mission availability due to their age and complex legacy systems.
Modern warfare also requires more advanced data sharing and sensor integration than earlier airborne warning aircraft were designed to support.
The E-7A offers improved mission system architecture that supports software upgrades and integration with future digital command networks.
However, the platform still faces challenges common to complex defense programs. Integration of mission systems, cybersecurity requirements, and testing timelines will determine the final operational performance.
The Bottom Line
The U.S. Air Force’s expanded E-7A Rapid Prototype program represents a major step toward replacing the aging E-3 fleet and strengthening the nation’s airborne command and control capabilities.
