BLUF: US Air Force Accelerates Electronic Warfare Transformation, E-11A Communications Relay Aircraft to Be Fully Retired by 2028, EA-37B Electronic Attack Aircraft Orders Nearly Doubled, Reflecting LEO Satellites and Modular Payloads as New Pillars of Battlefield Communications, Defense Supply Chain and Allied Cooperative Operations to Undergo Fundamental Change.
In a document submitted to Congress on April 30, 2026, the US Air Force clearly expressed its desire to nearly double orders for the EA-37B electronic attack aircraft while planning to fully retire the relatively young E-11A fleet by fiscal year 2028. This decision is not merely a platform replacement but represents a structural shift in the US military’s strategic thinking on battlefield communications and electronic warfare. This article interprets the far-reaching implications of this decision from three perspectives: technological maturity, industry chain impact, and future operational concepts.
Why Is the E-11A Retirement So Sudden and Controversial?
Answer Capsule: The E-11A, known as “Wi-Fi in the sky,” is a key asset for the US military to ensure communication in mountainous and complex electromagnetic environments, but the proliferation of low-Earth orbit (LEO) satellites and the maturity of podded payloads have significantly weakened the rationale for a dedicated fleet.
The E-11A is based on the Bombardier Global 6000 business jet, modified to carry the Battlefield Airborne Communications Node (BACN) payload. This system was initially designed to address communication dead zones in the mountains of Afghanistan—traditional VHF/UHF radios are limited by line of sight, and satellite communications (SATCOM) are expensive and cumbersome. Operating at high altitude, BACN acts as a bridge between different communication systems, integrating and forwarding data in various formats, allowing US and allied units to maintain real-time contact even behind terrain obstacles.
However, the US Air Force explicitly states in the document that the booming development of modern LEO satellite communications technology, especially the low-cost, high-bandwidth, low-latency connectivity provided by constellations like Starlink, can fill the communication gap left by the E-11A’s retirement. Additionally, podded BACN payloads have already been developed, and modernized versions can be deployed on various existing aircraft, eliminating the need for a dedicated fleet. This logic parallels the trend in commercial aviation of shifting from dedicated satellites to leased capacity, but the timeline for military application has come faster than expected.
What Is the Electronic Warfare Strategy Behind the EA-37B Increase?
Answer Capsule: The EA-37B is the US military’s latest electronic attack platform, focused on suppressing enemy radar and communication systems. The increase in orders reflects the US military’s heightened emphasis on countering Anti-Access/Area Denial (A2/AD) environments.
The EA-37B is also based on the Gulfstream G550 business jet but has a completely different mission. It carries the “Compass Call” system, capable of emitting powerful electromagnetic interference signals to paralyze enemy air defense radars, communication networks, and command links. In the envisioned Indo-Pacific battlefield, the PLA’s long-range air defense systems like HQ-9 and S-400 form a dense anti-access network, and the EA-37B’s jamming capability is a key non-kinetic means for the US military to breach this defense.
Nearly doubling the EA-37B procurement means the US Air Force is preparing for high-intensity conflict, not just maintaining low-intensity deployments from the counterterrorism era. This decision aligns with the US military’s recent heavy investment in Electromagnetic Spectrum Operations (EMSO)—electronic warfare is no longer a support role but a primary warfighting domain. Notably, the EA-37B’s airframe platform is the same business jet class as the E-11A, but the mission payload is entirely different, highlighting the US military’s pragmatic approach to platform selection: shared airframes, dedicated payloads, to reduce logistics costs.
How Can LEO Satellites Replace Dedicated Communications Relay Aircraft?
Answer Capsule: LEO satellite constellations provide global coverage, low latency, and high bandwidth communications services, allowing tactical units to obtain stable data links without relying on high-altitude dedicated aircraft, but this also introduces new vulnerabilities and dependency risks.
The US Air Force’s argument is technically valid. LEO satellites (e.g., Starlink, OneWeb) orbit at altitudes of only about 550 km, with signal latency below 20 milliseconds, and terminal equipment has become miniaturized and significantly cheaper. In operational environments like Afghanistan or the Middle East, the US military often needed to temporarily deploy communication nodes, and the E-11A’s flexibility was indeed unmatched; but as LEO satellite coverage increases, ground troops only need to carry a laptop-sized terminal to connect to a global broadband network, making the E-11A’s dedicated role awkward.
However, this transition is not without costs. LEO satellites themselves may become targets for adversaries—anti-satellite missiles, directed jamming, and cyber attacks can cripple constellations. Additionally, commercial satellite bandwidth may be squeezed by civilian traffic during wartime, and whether the US military has dedicated spectrum or priority remains undisclosed negotiation details. In contrast, the E-11A is an asset fully controlled by the US military, unaffected by external service interruptions. Retiring the E-11A effectively entrusts part of the reliability of communications relay to commercial partners, requiring significant strategic confidence.
How Significant Is the Impact of This Decision on the Defense Supply Chain?
Answer Capsule: Bombardier will lose an important military aftermarket, while electronic warfare system suppliers like BAE Systems will gain long-term orders; the trend of modular payloads will also change the business model of the aircraft modification industry.
Below is an impact analysis of key stakeholders:
| Stakeholder | Impact | Specific Figures/Events |
|---|---|---|
| Bombardier (E-11A platform manufacturer) | Negative: Loss of logistics maintenance and upgrade contracts | US Air Force currently has about 10 E-11As, all retired by 2028 |
| BAE Systems (EA-37B payload supplier) | Positive: Increased orders expand production capacity | Procurement from about 10 to nearly 20 aircraft |
| Gulfstream Aerospace (EA-37B platform manufacturer) | Positive: Stable G550 military modification orders | Each EA-37B modification costs about $150 million |
| LEO satellite operators (SpaceX, etc.) | Positive: Increased military contract opportunities | US Air Force has already purchased Starlink military terminals |
| Allied operating units | Neutral to negative: Need to adjust communication protocols and training | NATO countries need to upgrade terminal equipment for LEO satellite compatibility |
This decision also accelerates the trend of “payload-platform separation.” In the future, the US military may prefer to procure common business jets and then quickly swap payload pods based on mission requirements, rather than maintaining multiple specialized aircraft types. This presents both opportunities and challenges for the aircraft modification industry—manufacturers need to develop standardized interfaces and rapid conversion kits, rather than designing systems for a single platform.
How Should Allies and Partners Respond?
Answer Capsule: Allies must accelerate the deployment of LEO satellite terminals and adjust joint communication protocols; meanwhile, the EA-37B increase may prompt allies to follow suit in investing in electronic attack capabilities.
The US military’s decision will not only affect itself. Within the NATO and Five Eyes framework, allies have long relied on the E-11A for communication bridging services. Once the E-11A is retired, allies must ensure their own communication systems can directly interface with LEO satellites, otherwise, there may be disconnects in joint operations. This means defense ministries need to procure compatible terminals in advance and modify the relay rules for tactical data links (e.g., Link 16).
On the other hand, the EA-37B increase sends a clear signal to allies: electronic attack is a necessary capability for future high-intensity conflict. Countries like the UK, Australia, and Japan may accelerate their own electronic warfare aircraft procurement or upgrade plans. For example, the UK Royal Air Force’s “Shadow” R2 electronic warfare aircraft program may receive more budget support as a result.
Why Is the Timing of This Shift Worth Noting?
Answer Capsule: 2026 coincides with the US military budget review cycle, and the Indo-Pacific situation continues to heat up; this decision directly responds to the urgent need to counter A2/AD environments.
The US Air Force’s proposal at this time aligns with the geopolitical clock. In 2026, the National Defense Authorization Act (NDAA) is undergoing its annual review, and each service must propose force structure adjustments for the next five years. The EA-37B increase and E-11A retirement fit perfectly with the US military’s transformation axis from counterterrorism to great power competition.
From a technological maturity perspective, LEO satellites underwent military validation phases between 2024 and 2025, including live testing by US forces in European and Indo-Pacific commands. These test results apparently gave decision-makers sufficient confidence in the reliability of commercial constellations. Meanwhile, the development of podded BACN payloads completed critical design review in 2025, meeting production conditions.
How Will Battlefield Communications and Electronic Warfare Evolve Over the Next Five Years?
Answer Capsule: We will see more combinations of “software-defined payloads” and “distributed communication nodes,” dedicated fleets gradually disappear, and common platforms and commercial services become mainstream.
Below is a possible development path:
timeline
title US Military Electronic Warfare and Communications Relay Evolution Roadmap
2026-2027 : EA-37B increase contract signed
: E-11A begins phased retirement
: Large-scale deployment of LEO satellite military terminals
2028-2029 : E-11A fully retired
: Podded BACN payload completes combat readiness testing
: EA-37B achieves initial operational capability
2030 onward : Software-defined payloads become widespread
: Multi-platform common electronic warfare pods
: Commercial satellites become tactical communications backbone
This roadmap shows that the US military is shifting from "hardware-centric" to "payload-centric." In the future, a C-130, P-8, or MQ-9 could carry BACN or electronic warfare pods, performing missions that previously only dedicated aircraft could accomplish. This flexibility will significantly enhance the US military's adaptability in dynamic battlefields.What Are the Implications of This Decision for Taiwan and Regional Security?
Answer Capsule: Taiwan should pay attention to the military applications of LEO satellite communications and assess the possibility of introducing similar podded payloads to strengthen communication resilience in complex terrain and electromagnetic environments.
In Taiwan’s defense scenario, the Central Mountain Range also creates communication dead zones, and the PLA’s electronic jamming capabilities are increasing. The US military’s experience shows that LEO satellites combined with airborne relay nodes are an effective solution to overcome terrain and electromagnetic countermeasures. Taiwan could consider integrating podded relay systems on its existing F-16V or P-3C fleets and establishing partnerships with commercial LEO satellite service providers.
Additionally, the EA-37B increase reminds Taiwan that electronic attack and defense capabilities need to be upgraded simultaneously. Taiwan’s Information, Communications, and Electronic Warfare Command should study how to use systems similar to “Compass Call” to suppress landing force communications and navigation systems during defensive operations.
Summary: What Is the Real Signal of This Decision?
The US Air Force’s plan, on the surface, is a platform replacement, but in reality, it is a redefinition of the entire operational concept. It conveys three core signals:
First, military communications are shifting from “dedicated assets” to “commercial services”—the maturity of LEO satellites gives the US military confidence to outsource critical missions to civilian systems.
Second, electronic warfare has been promoted from a support role to a primary warfighting domain—the EA-37B increase indicates the US military is prepared to launch electromagnetic attacks at the first moment of conflict.
Third, modularity and commonality will become mainstream in future military aircraft design—any platform with the right payload can perform multiple missions, and the era of dedicated fleets is ending.
Below is data supporting these three trends:
| Trend | Specific Evidence | Source/Link |
|---|---|---|
| Militarization of LEO satellites | US Air Force has purchased Starlink military terminals | SpaceX Starshield official page |
| Increased investment in electronic warfare | EA-37B procurement increased from 10 to nearly 20 aircraft | US Air Force budget documents |
| Proliferation of modular payloads | BACN pod completed development testing | BAE Systems BACN page |
For investors and industry observers, the impact of this decision extends far beyond the military sphere. LEO satellite communications, electronic warfare systems, aircraft modification industry, and software-defined payloads will all see new growth drivers. For Taiwan and other allies, now is the critical moment to adjust their own communications and electronic warfare strategies.
How Will the US Military Ensure a Smooth Transition from E-11A to LEO Satellites?
Answer Capsule: The US military will adopt a phased retirement and transition strategy, first retaining a small number of E-11As as backup while expanding LEO satellite terminal deployment and podded payload testing to ensure no capability gap.

This flowchart shows that the US military is not retiring the E-11A abruptly but using a dual-track parallel strategy to ensure no gap in communications relay capability. Notably, the development of podded BACN payloads is key—if progress lags, the E-11A retirement timeline may be delayed. But based on available information, the US military is highly confident in this technology.What Inspiration Does This Decision Offer to the Tech Industry?
Answer Capsule: Military technology is accelerating the adoption of commercial off-the-shelf (COTS) solutions; the case of LEO satellites and modular payloads is worth rethinking product strategies for defense tech startups and traditional contractors.
The US Air Force’s decision offers at least two levels of inspiration for the tech industry. First, the importance of hardware platforms is declining, while the value of software and payloads continues to rise. In the past, winning a military aircraft contract meant a long-term monopoly on the aftermarket; now, if payloads can be quickly swapped, platform suppliers’ bargaining power will be weakened. Second, the military application of commercial satellite services is no longer theoretical but actual policy. This means that the military divisions of companies like Starlink and OneWeb will see explosive growth, and suppliers of related terminal equipment and data processing software will also benefit.
For Taiwan’s defense tech companies, this trend offers opportunities to enter the international supply chain. For example, developing tactical terminals compatible with LEO satellites or designing universal payload racks for existing US military aircraft are directions worth pursuing.
Conclusion: Transformation Always Comes with Risks, but the Cost of Stagnation Is Higher
The US Air Force’s decision to propose this bold transformation plan in 2026 shows that decision-makers have a very clear judgment of the future battlefield: communications relay will be handled by LEO satellites and modular payloads, while electronic attack will be executed by the EA-37B. This decision is not without risks—the anti-jamming capability of LEO satellites, the maturity of podded payloads, and the cooperation of allies are all variables that need continuous monitoring. But from a strategic perspective, stagnating in old models, continuing to invest precious budget and manpower in outdated dedicated platforms, carries a higher cost than transformation.
For industry observers, this decision heralds the direction of military aviation development over the next decade: fewer dedicated aircraft, more common platforms, greater reliance on commercial services, and increased emphasis on electronic warfare. Those who can seize these trends will gain a leading position in the next phase of the defense technology race.
