Electronically Scanned Arrays Market Size
The electronically scanned arrays market was valued at USD 9,6 billion in 2025 and is projected to reach USD 10.3 billion in 2026 and USD 20.3 billion by 2035, expanding at an approximately 7.8% CAGR during 2026 to 2035.
Electronically Scanned Arrays Market Key Takeaways
Market Leader: Northrop Grumman led with over 13.60% market share in 2025.
Leading Players: Top 5 players in this market include Northrop Grumman, RTX Corporation, Lockheed Martin Corporation, Saab AB, General Dynamics Corporation, which collectively held a market share of 48% in 2025.
ESA systems steer a beam by controlling phase electronically across an aperture, allowing radar, communications, and electronic-warfare functions to shift without mechanical repositioning. That capability is becoming central to air and missile defense, combat-aircraft upgrades, naval sensing, airborne ISR, and satellite connectivity.
Demand is increasingly tied to funded platform programmes rather than isolated radar refreshes. Global military expenditure reached USD 2.718 trillion in 2024, up 9.4% in real terms, widening the pool of air-defense, aircraft, and naval modernization budgets that can carry ESA content [1]Stockholm International Peace Research Institute, "Trends in World Military Expenditure, 2024," April 2025, sipri.org. At the same time, GaN-based arrays are moving from a technology differentiator into a design baseline for high-power, wide-bandwidth programmes, raising the value of qualified T/R-module capacity and integration expertise.
GMI Analyst View
Our market estimates show a market that is expanding through two procurement logics: long-cycle defense programmes and volume-oriented satellite connectivity. The former rewards suppliers able to clear qualification, security, and integration gates; the latter pressures the same component base toward repeatable manufacturing. The resulting opportunity is not simply more radar demand. It is a shift toward suppliers that can protect performance at the aperture while reducing the cost and lead time of GaN modules.
The main boundary condition is execution. A funded order does not translate immediately into installed-array revenue when platform certification, export approval, thermal design, and software integration remain on the critical path. Established primes retain an advantage where the array is inseparable from a combat-system architecture, while domestic programmes in India and South Korea create credible routes for regional suppliers to accumulate manufacturing learning.
Key Drivers
Defense modernization is converting budgets into programme-specific array demand
RTX received a USD 1.7 billion LTAMDS award in 2025, taking cumulative programme value to USD 3.8 billion, for nine GaN AESA radars for the U.S. Army and Poland; 94 radars are planned for U.S. forces [2]RTX Corporation, "RTX awarded $1.7 billion contract for LTAMDS," September 2025, rtx.com. Northrop Grumman's APG-83 SABR programme, approved for full-rate production in September 2024, has exceeded USD 1.7 billion in contract value across F-16 modernization customers. Such awards matter because radar replacement is coupled to platform sustainment, weapons integration, and mission-system upgrades, creating follow-on integration and support work in addition to array deliveries.
GaN adoption raises capability while concentrating qualification value
RTX's September 2025 APG-82(V)X announcement placed GaN in an open-architecture F-15 radar designed to extend detection and electronic-warfare functions [3]RTX Corporation, "RTX unveils new APG-82(V)X radar enhanced with gallium nitride," September 2025, rtx.com. Lockheed Martin's first delivery of four AN/SPY-7(V)1 antenna arrays to Japan for an Aegis System Equipped Vessel shows that GaN systems are also moving through naval production milestones. Higher power density and thermal performance can improve aperture output, but the same features make yield, cooling, and module screening central procurement constraints.
ISR and satellite use broaden the addressable platform base
South Korea selected an L3Harris/IAI team for a KRW 3.1 trillion AEW&C II programme involving four aircraft with EL/W-2085 dual-band GaN AESA radar. In civilian aviation infrastructure, the FAA reported Data Comm En Route deployment across all 20 U.S. Air Route Traffic Control Centers, serving 68 operators and more than 8,000 equipped aircraft. The two demand streams have different purchase cycles, limiting reliance on any one fighter or ground-defense programme.
Key Restraints
Array performance is purchased with system-level complexity
A production AESA must reconcile semiconductor yield, T/R-module calibration, thermal management, beamforming software, electromagnetic compatibility, and platform interfaces. India's Uttam programme illustrates the industrialization burden: a 2025 order for 122 active antenna array units and 121 interface frames supports Tejas Mk1A integration from the 41st aircraft onward. Domestic content does not eliminate qualification risk; it transfers more of the schedule and production-learning burden into the local supply chain.
Export controls and airworthiness approvals further fragment the market. Defense arrays combine controlled hardware, software, and performance parameters, making foreign delivery dependent on licensing and government-to-government alignment. This favors suppliers with established customer-country approvals, but it also creates room for indigenous alternatives where customers prioritize sovereign supply and are willing to accept a longer development path.
GMI Analyst View
Our analysis indicates that the market's strongest demand signals are also its principal delivery risks. LTAMDS, SPY-7, and AEW&C II demonstrate that customers are buying mission-level outcomes, not interchangeable antenna panels. As a result, primes with proven combat-system integration can command a premium, while component suppliers must demonstrate repeatability before demand converts into volume.
The restraint is therefore not a lack of applications. It is the time required to turn a GaN aperture into a certified, exportable capability. Suppliers that design for modular upgrades and build qualified regional manufacturing options are better positioned to convert procurement backlogs into recurring revenue without being constrained by a single foundry or licensing channel.
Electronically Scanned Arrays Market Segment Analysis
By Type
AESA generated USD 5,386.1 million in 2025 and is projected to reach USD 10,797.7 million by 2035 at an approximately 7.25% CAGR. Distributed T/R modules permit beam steering and multiple functions with greater redundancy than a centralized-transmitter architecture, explaining AESA's leading position in combat-aircraft, naval, and air-defense programmes. PESA, valued at USD 4,250.4 million in 2025 and projected to reach USD 9,498.7 million by 2035, is forecast to grow at approximately 8.42% CAGR. Its cost and manufacturing profile suits applications where electronic steering is needed but full AESA concurrency is not economically justified.
By Array Geometry
Planar arrays dominate demanding air, naval, and fixed-site apertures because they support high-gain two-dimensional steering. Linear and frequency-scanning arrays remain relevant where one-axis coverage or simpler beamforming reduces system cost. Single-frequency systems were the larger segment at USD 4,911.7 million in 2025 and are forecast to grow at approximately 6.95% CAGR.
By Frequency Band
X-, S-, L-, and C-band requirements remain tied to distinct fire-control, surveillance, and weather missions. Multifrequency systems, valued at USD 4,724.9 million, are forecast to grow at approximately 8.58% CAGR because a single platform can combine search, tracking, and electronic-warfare functions rather than carry separate apertures.
By Range, Platform
Short-range arrays address point defense and counter-UAS missions; medium-range systems support tactical surveillance and naval air defense; long-range arrays carry the higher-value early-warning and missile-defense missions.
By Platform
Air platforms concentrate fighter and AEW&C demand, while naval arrays gain from fixed-face, multi-mission installations. Ground platforms are tied to air-defense recapitalization, and space systems are supported by phased-array payloads and terminals.
By Application
Radar remains the core application, but communications, navigation, and electronic warfare increase array content per platform.
By End Use
Defense & Military demand spans air surveillance and early warning, fire control and missile guidance, EW and jamming, naval radar and maritime surveillance, ground-based air defense, and ISR and reconnaissance. Civilian & Commercial use includes air traffic control and management, weather monitoring, satellite communications, navigation, and other applications.
GMI Analyst View
Our assessment suggests that PESA's faster forecast growth should be read as an adoption-economics signal rather than a reversal of AESA's technical advantage. Customers that need better revisit rates or electronic steering but cannot absorb a full distributed-module architecture have a viable intermediate option. That expands the served market, particularly in retrofit, surveillance, and cost-sensitive programmes.
Multifrequency growth is more strategically consequential. It shifts value toward system suppliers that can manage antenna, power, cooling, and signal-processing trade-offs across bands. The commercial implication is a widening gap between selling an aperture and supplying a configurable sensor: the latter earns more integration value but also assumes more certification and sustainment responsibility.

Asia Pacific is projected to grow from USD 2,961.4 million in 2025 to USD 7,002.2 million by 2035, at approximately 9.03% CAGR. China, valued at USD 1,165.0 million in 2025 and forecast to grow at approximately 9.69% CAGR, combines scale with local supply development. India, valued at USD 508.0 million and the fastest-growing major regional market at approximately 11.23% CAGR, is building Uttam production capacity. Japan, valued at USD 555.8 million and forecast to grow at approximately 8.57% CAGR, accepted the first SPY-7 shipset for its first Aegis System Equipped Vessel, planned for fiscal-year 2027 commissioning [5]Lockheed Martin Corporation, "Aegis System Equipped Vessel Takes Shape: Lockheed Martin Delivers AN/SPY-7(V)1 Radar Antennas to Japan," July 2025, news.lockheedmartin.com.
Australia, valued at USD 97.7 million and forecast to grow at approximately 5.10% CAGR, remains more dependent on allied procurement channels. South Korea, valued at USD 460.2 million and forecast to grow at approximately 7.89% CAGR, is extending demand from fighter arrays into airborne surveillance through its KF-21 and AEW&C II programmes.
Latin America's USD 374.3 million 2025 market and Middle East & Africa's USD 413.6 million market are smaller, with demand concentrated in imported air defense, maritime surveillance, and combat-aircraft upgrades across Brazil, Mexico, Argentina, South Africa, Saudi Arabia, and the UAE.
South Africa, valued at USD 82.6 million in 2025 and forecast to grow at approximately 6.17% CAGR, Saudi Arabia, valued at USD 122.9 million and forecast to grow at approximately 6.37% CAGR, and the UAE, valued at USD 96.7 million and forecast to grow at approximately 6.85% CAGR, represent the specified Middle East & Africa country markets.
GMI Analyst View
We expect Asia Pacific to narrow the gap with North America because its growth is supported by multiple national industrial strategies rather than one regional procurement mechanism. India's Uttam order, Japan's SPY-7 vessel integration, and South Korea's AEW&C II selection establish demand across domestic production, allied imports, and airborne ISR. That diversity makes the region less dependent on a single platform class.
North America remains the largest market because mature programmes and installed fleets generate both new-build and sustainment demand. Europe occupies a different position: budget expansion can accelerate array orders, but cross-border development and certification arrangements mean that capacity and programme governance are as important as aggregate defense spending. Suppliers should therefore treat regional growth rates as indicators of procurement timing and access conditions, not as interchangeable demand pools.
