First Flight of the EA-37B Compass Call: A New Era in Electronic Warfare

The United States Air Force (USAF) has taken a significant step forward in modernizing its electronic warfare capabilities with the successful first training sortie of the EA-37B Compass Call. Conducted in early May 2025 by the 43rd Electronic Combat Squadron at Davis-Monthan Air Force Base in Arizona, this sortie marks a pivotal milestone in the transition from the aging EC-130H fleet to a new generation of electronic attack aircraft.

Built on a heavily modified Gulfstream G550 business jet platform, the EA-37B is designed to disrupt enemy communications, radar, and command and control networks. This modernization comes at a time when electronic warfare is becoming increasingly central to maintaining air superiority and operational success in contested environments. The EA-37B’s debut reflects years of coordination between defense contractors, Air Force personnel, and strategic planners.

As adversaries develop more advanced air defense systems and electronic countermeasures, the need for faster, more agile, and more survivable platforms has become paramount. The EA-37B promises to deliver on these requirements, offering enhanced speed, range, and altitude capabilities, while integrating next-generation electronic warfare systems.

Modernizing the Compass Call: From EC-130H to EA-37B

The Legacy of the EC-130H

The EC-130H Compass Call has been a cornerstone of the USAF’s electronic warfare fleet since the 1980s. Based on the Lockheed C-130 Hercules airframe, it was developed to jam enemy communications and radar, playing a critical role during conflicts in Iraq and Afghanistan. However, the platform’s age and limitations in speed, range, and survivability have increasingly hindered its effectiveness in modern combat scenarios.

With some airframes dating back to the Vietnam War, the EC-130H’s operational lifespan has reached its limit. The USAF has already retired nine of its 14 EC-130Hs, underscoring the urgency of transitioning to a more capable platform. The need for a replacement that could integrate with modern joint force operations and provide enhanced mission effectiveness led to the development of the EA-37B.

The EC-130H’s contributions to electronic warfare are undeniable, but the threat landscape has evolved. Adversaries now employ more sophisticated integrated air defense systems (IADS), requiring aircraft that can operate with greater stealth, speed, and agility, all areas where the EA-37B is expected to excel.

“The EA-37B mission culminates years of planning and coordination between thousands of people spanning many organizations,” Lt. Col. Tray Wood, Commander, 43rd Electronic Combat Squadron

The EA-37B Platform and Capabilities

The EA-37B is built on the Gulfstream G550, a commercial business jet known for its speed, altitude performance, and advanced avionics. This choice reflects a growing defense trend of adapting commercial airframes for military roles to reduce costs and improve maintainability. The aircraft is equipped with classified electronic attack systems capable of jamming enemy communications, radar, and navigation signals.

In addition to offensive capabilities, the EA-37B can also disrupt enemy air defense networks and defuse roadside bombs remotely. These features enable U.S. and allied aircraft to penetrate deeper into contested airspace with reduced risk. Compared to the EC-130H, the EA-37B flies nearly twice as fast, has double the range, and can operate at,000,000,000 feet higher.

Production of the EA-37B is a collaborative effort between BAE Systems and L3Harris. BAE is responsible for the electronic warfare systems, while L3Harris integrates these systems into the modified G550 airframes at its Waco, Texas facility. Gulfstream, the original manufacturer of the G550, modifies the aircraft’s external design to accommodate the new technologies at its facility in Savannah, Georgia.

Strategic Importance and Future Role

The EA-37B is more than just a replacement aircraft, it is a strategic asset designed to ensure U.S. dominance in the electromagnetic spectrum. As the nature of warfare shifts towards information and network-centric operations, electronic attack capabilities will play a central role in disrupting enemy situational awareness and command structures.

Lt. Col. Jesse Szweda, Director of Operations for the 43rd Squadron, emphasized that the EA-37B and its supporting personnel represent “the most recent evolution in a long history of electromagnetic spectrum dominance.” This evolution aligns with the Department of Defense’s broader modernization goals, which include integrating artificial intelligence, machine learning, and autonomous systems into future combat operations.

Looking ahead, the USAF expects to receive all ten EA-37Bs by 2028, with the first delivered in August 2024. As training progresses and operational capabilities are validated, the fleet will gradually assume the mission set currently held by the EC-130H, ensuring a seamless transition and uninterrupted electronic warfare support.

Conclusion

The first training sortie of the EA-37B Compass Call represents a critical inflection point in the USAF’s electronic warfare modernization. By transitioning from the aging EC-130H to a faster, more capable, and more survivable platform, the Air Force is positioning itself to counter emerging threats in increasingly contested environments.

This milestone reflects not only technological progress but also the successful collaboration between industry and government. As the EA-37B moves toward full operational capability, it will provide the U.S. and its allies with a decisive edge in the electromagnetic battlespace, a domain that is rapidly becoming as critical as land, sea, air, and space.

NATO Expected to Select Saab GlobalEye to Replace AWACS Fleet

NATO is set to announce the Saab GlobalEye as its E-3A Sentry replacement at the July 2026 Ankara summit, bypassing Boeing’s E-7 Wedgetail.

Published

on

This article summarizes reporting by Reuters by Sabine Siebold and Tim Hepher.

The North Atlantic Treaty Organization (NATO) is preparing to select the Saab GlobalEye to replace its aging fleet of Boeing E-3A Sentry airborne warning and control system (AWACS) aircraft, marking a significant shift toward European defense procurement. The official announcement is expected during the upcoming NATO summit in Ankara, Turkey, scheduled for July 7 and 8, 2026.

According to reporting by Reuters, four sources familiar with the matter indicated that the alliance will pivot away from its previous intention to acquire the Boeing E-7 Wedgetail. The decision represents a major defense contract for Sweden-based Saab AB and a notable setback for The Boeing Company in the airborne early warning and control (AEW&C) market. Neither NATO nor Saab has officially commented on the pending announcement.

Transitioning from the E-3A Sentry

NATO currently operates a fleet of 14 Boeing E-3A Sentry AWACS aircraft. Based at Geilenkirchen Air Base in Germany, these aircraft have been in service since 1982 and are approaching the end of their operational lifespan. The Saab GlobalEye, which completed its first flight in 2018, utilizes a modified Bombardier Global 6000 or 6500 business jet airframe equipped with Saab’s Erieye extended-range radar system.

The Boeing E-7 Wedgetail fallout

The anticipated selection of the GlobalEye follows a series of procurement shifts regarding the Boeing E-7 Wedgetail. NATO had initially planned to purchase six E-7 aircraft to replace the E-3A Sentry fleet. The alliance abandoned this plan in 2025 after the United States Department of Defense (Pentagon) canceled its own procurement of 26 Wedgetails in favor of satellite-based surveillance networks.

U.S. Secretary of Defense Pete Hegseth indicated to Congress in May 2026 that the Pentagon is attempting to reinstate the E-7 into the budget following pressure from U.S. lawmakers. Despite these efforts, international momentum appears to be shifting toward the Swedish manufacturer. On May 27, 2026, Canadian Prime Minister Mark Carney announced that the Government of Canada had entered formal negotiations with Saab as the preferred supplier for its own AEW&C program, bypassing the Boeing platform.

AirPro News analysis

We view NATO’s expected selection of the Saab GlobalEye as a critical indicator of changing procurement dynamics within the alliance. Historically, NATO has relied heavily on U.S.-manufactured heavy surveillance platforms. The shift to a European-integrated system on a Canadian business jet airframe suggests a growing preference for diversified defense supply chains and potentially lower operating costs compared to commercial airliner-based platforms like the E-7. If confirmed at the Ankara summit, this contract will solidify Saab’s position as a primary competitor in the global AEW&C market while placing additional pressure on Boeing’s defense sector to secure international orders for the Wedgetail program.

UK Commits 5 Billion to Drones in 298 Billion Defence Plan

The UK Ministry of Defence unveils a 298 billion Defence Investment Plan, including 5 billion for uncrewed and autonomous systems.

Published

on

The United Kingdom Ministry of Defence committed £5 billion to uncrewed and autonomous systems as part of a broader £298 billion Defence Investment Plan unveiled on June 29 and June 30, 2026. The funding marks the largest drones procurement initiative in British military history, signaling a strategic pivot toward hybrid crewed and uncrewed operations across the Royal Air Force, Royal Navy, and British Army.

Announced by Prime Minister Keir Starmer and Defence Secretary Dan Jarvis, the four-year spending blueprint aims to modernize depleted armed forces by applying direct lessons from recent conflicts. According to official government statements, the plan establishes a new Uncrewed Systems Taskforce to accelerate the deployment of autonomous capabilities and includes the opening of Europe’s largest drone testing facility, the Uncrewed Systems Centre, in Swindon, England.

Strategic shift toward autonomous warfare

The £5 billion allocation specifically targets the rapid acquisition and deployment of strike, protector, and surveillance drones. The Ministry of Defence explicitly cited the ongoing war in Ukraine, where forces consume approximately 200,000 drones per month, and recent Middle East conflicts involving the launch of up to 700 offensive drones per day, as the primary drivers for this doctrinal shift.

Defence Secretary Dan Jarvis outlined the scope of the hardware acquisition during his parliamentary statement, noting the funding will cover anti-submarine vessels, uncrewed ground vehicles, and autonomous systems designed to operate alongside traditional fighter jets.

In a press release detailing the operational integration of these new assets, the Ministry of Defence stated:

“The £5 billion investment will see Britain build a flexible, integrated force with attack drones flying alongside Army helicopters, RAF jets made invisible from enemy detection with new drones, and a hybrid Royal Navy made up of crewed and uncrewed vessels.”

Aerospace and naval procurement allocations

Beyond the dedicated drone funding, the Defence Investment Plan outlines significant capital for traditional and next-generation aerospace programs. The government allocated £8.6 billion to the Global Combat Air Programme (GCAP), a joint venture with Italy and Japan to develop the Tempest sixth-generation fighter jet. An additional £300 million is earmarked specifically for the development of Collaborative Combat Aircraft (CCA), which will fly in tandem with crewed fighters.

The broader £298 billion package, which targets a defense spending level of 2.7 percent of the national gross domestic product, includes £64 billion to renew the nuclear deterrent, build new submarines, and procure Lockheed Martin F-35A Lightning jets. Space capabilities will receive £3.2 billion, while £11 billion is dedicated to replenishing munitions and weapons stockpiles.

The integration of autonomous systems is also reshaping naval procurement. Defense industry reports indicate the Royal Navy is shifting its surface fleet strategy, opting to forgo the previously planned Type 83 destroyers. Instead, the service will pursue at least six new hybrid air defense warships engineered specifically to operate in concert with uncrewed maritime vessels.

AirPro News analysis

We note that while the UK government is framing the £15 billion funding boost over previous budget estimates as a historic modernization effort, it falls short of the £28 billion originally requested by defense officials. This discrepancy suggests that despite the heavy emphasis on rapid, low-cost autonomous systems, the Ministry of Defence may still face procurement gaps in its traditional, long-term acquisition programs.

The timing of the announcement carries significant political weight. With Prime Minister Starmer reportedly preparing to step down, the Defence Investment Plan is positioned as a capstone legacy project. However, the heavy reliance on uncrewed systems like the StormShroud autonomous collaborative platform reflects a permanent doctrinal shift for the UK military. The strategy clearly moves away from relying solely on exquisite, low-volume crewed platforms, pivoting toward mass-producible autonomous assets that can sustain the high attrition rates observed in modern combat environments.

The U.S. Army Aviation and Missile Command (AMCOM) and The Boeing Company have successfully adapted a ground-vehicle diagnostic system to service the Boeing AH-64E Apache helicopter, completing a 12-month operational pathfinder exercise at Fort Rucker, Alabama, that demonstrated significant reductions in sustainment costs.

Announced by the U.S. Army on May 12, 2026, the initiative utilized the Next Generation Automatic Test System (NGATS) to diagnose faults directly on the flightline. Historically used for ground vehicles like the Stryker and Abrams, the system’s expansion into aviation allows maintainers to avoid unnecessary depot shipments and limit demand on the global supply chain.

Adapting ground diagnostics for aviation readiness

The pathfinder exercise involved collaboration between AMCOM, Boeing, PAE Maneuver Air, and M1. The foundation for the exercise was laid on December 1, 2025, when Boeing Global Services upgraded NGATS capabilities to include the first aviation test program set. This upgrade enabled the system to interface with complex aviation electronics that previously required specialized, separate testing equipment.

The U.S. Army Aviation Center of Excellence at Fort Rucker provided a rigorous testing environment for the program. The installation conducts 40 percent of the Army’s aviation flight hours and operates the equipment equivalent of five combat aviation brigades. Testing the system under this high operational tempo allowed the Army to validate the diagnostic tool’s effectiveness in a realistic sustainment scenario.

During the 12-month exercise, the Army reported over $1 million in cost avoidance on a single component, the Aircraft Interface Unit, by utilizing NGATS alongside Boeing-developed test procedures.

“Leveraging existing technology like NGATS to its maximum effect is going to show real returns for Army aviation,” stated Col. Tim Harloff, Commander of the AMCOM Combined Logistics Command.

Long-term sustainment and future expansion

The Boeing AH-64E Apache is projected to remain in service into the 2060s, making long-term maintenance efficiency a priority for the Department of Defense. On January 2, 2026, the U.S. Army awarded Boeing a $2.73 billion contract for post-production support services for the Apache fleet through 2030. The integration of NGATS aligns with the objectives of this sustainment contract by streamlining repairs and reducing the logistical footprint required to keep the aircraft operational.

Following the success of the AH-64E Apache pathfinder exercise, Boeing plans to expand NGATS testing capabilities to additional aviation platforms, unmanned aircraft, and watercraft. Col. John Morris, Chief of Staff for AMCOM, noted the value of the joint effort, stating that the Army will see consistent wins when collaborating across industry partners.

AirPro News analysis

We view the successful integration of NGATS into the Boeing AH-64E Apache maintenance ecosystem as a critical step in the U.S. Army’s broader modernization strategy. By shifting diagnostic capabilities from centralized depots directly to the flightline, the military can significantly reduce aircraft downtime and alleviate pressure on an already strained aerospace supply chain. The $1 million cost avoidance on a single component suggests that scaling this technology across the broader aviation fleet could yield substantial financial and operational benefits over the lifecycle of these aircraft.
