Collectively, European procurement sustains the electronically scanned array radar market share above 25% through the forecast window.
Regulatory Landscape
Electronically scanned array radars operate under dual-use and defense export-control regimes that shape cross-border programs and component sourcing. In the United States, many AESA/ESA radar technologies fall under ITAR (USML Category XI), and depending on configuration, can also trigger Export Administration Regulations controls administered by the Bureau of Industry and Security (BIS). For certain national-security controlled items, this includes worldwide license requirements introduced in late 2024 under 15 CFR 742.4.
In Europe, surveillance radar implementation and associated avionics integration are influenced by equipment and interoperability requirements tied to the Single European Sky framework. International coordination through the Wassenaar Arrangement dual-use control lists continues to guide licensing approaches for sensitive radar-related technologies, including the 2025 list correction published in early 2026. On the funding and industrial-policy side, the European Defence Fund (EDF) 2026-2027 indicative perspective flags collaborative development priorities for multifunction RF systems, reinforcing compliance-driven preferences for sovereign and interoperable architectures alongside exportable configurations.
Value Chain Analysis
The ESA radar value chain begins with upstream materials and semiconductor fabrication for GaN/GaAs, then extends into wafer processing, RF power devices, packaging, and thermal-interface solutions that feed transmit/receive module manufacturing. Midstream suppliers provide high-reliability microelectronics, specialized PCBAs, power-supply line-replaceable units, and timing/control components, which primes and integrators then combine into antenna apertures/radomes, back-end receivers/exciters, and digital signal processing for airborne, land, naval, and space/HAPS platforms.
Downstream, primes deliver line-fit radars to OEM and shipyard new-build programs and execute retrofit/upgrade kits through depot-level integration, supported by long-life sustainment that includes spares, software updates, and obsolescence management. Recent supply-chain actions highlight concentration around the GaN and module stack: HENSOLDT entered a long-term agreement with United Monolithic Semiconductors (UMS) to secure 900,000 GaN components by 2030, while Neways signed a long-term partnership with Thales (10-year duration) to secure radar-related electronic solutions. Localization and partner sourcing have also become more visible, including Lockheed Martin and Fujitsu contracting for SPY-7 subarray-suite power supply LRUs to support a Japan-based supply chain for Japan Maritime Self-Defense Force Aegis System Equipped Vessels.

Market Opportunities and Future Outlook
A meaningful opportunity sits in legacy platform modernization, where AESA retrofits can deliver multi-mission capability without full platform replacement, which aligns with the report scope that excludes software-only upgrades. Program traction includes Northrop Grumman reaching its 1,000th AN/APG-83 SABR delivery (May 2026), plus additional U.S. Department of Defense contracting for AN/APG-83 sets for USAF F-16s (June 2026). Together, these orders support continued demand for retrofit-capable AESA hardware and the installation and support ecosystems around it.
In Europe, near-term demand is closely tied to Typhoon and broader NATO interoperability-driven upgrades, supported by funded production and test activity rather than conceptual roadmaps. The UK Ministry of Defence placed a GBP 453 million contract to manufacture 40 ECRS Mk2 AESA radars for RAF Typhoon (January 2026), and Indra with HENSOLDT commenced live operational testing of ECRS Mk1 for German and Spanish Eurofighter fleets (June 2026). This expands the addressable market for multifunction apertures and software-defined modes across allied fleets. India adds a parallel opportunity track through indigenous development and program-specific radar creation, supported by Centum Electronics securing a contract from Hindustan Aeronautics Ltd to design and develop an AESA radar for the Utility Helicopter-Maritime program (February 2026), which extends demand for domestic module supply, packaging, and qualification capacity.

Data Sources, Market Sizing, and Validation
Desk Research
Desk research is used to build the base structure of the model and to set realistic guardrails on demand and supply. We reviewed public defense budget documents and procurement releases (such as US DoD budget justification books), parliamentary or audit reports on major programs, and defense trade and customs statistics where applicable.
To anchor technical and deployment context, we also relied on NATO and national MoD publications, aviation and maritime regulator data for platform fleets, peer-reviewed radar and RF engineering journals, and patent databases for AESA and related antenna technologies. Company annual reports, contract announcements, and investor presentations were used to map program timing, delivery waves, and upgrade cycles, and then cross-checked with a paid subscription database for company financials and a global contracts and tenders feed. These examples are not exhaustive, and other public sources were also used for collection, validation, and clarification.
Primary Interviews and Surveys
Primary work was done through interviews and structured surveys with radar OEM-facing stakeholders, subsystem suppliers, defense procurement and sustainment personnel, and domain experts covering air, land, and naval radar deployments. Because the market is global, we balanced inputs across the main buying regions so that platform demand, upgrade pacing, and pricing assumptions could be checked against observed program behavior.
Distribution of primary research fieldwork respondents
| Company type | Respondent position | Region |
|---|---|---|
| Top tier: 29% | CXOs: 17% | APAC: 39% |
| Mid tier: 54% | Functional/Unit leaders: 25% | EMEA: 34% |
| Smaller Players: 17% | Managers: 58% | Americas: 27% |
Market-Sizing & Forecasting
Market sizing starts with a top-down build where defense and aerospace procurement outlays, program counts, and platform fleet inventories are used to reconstruct the addressable radar demand pool by year, and then filtered to electronically steered arrays. Where the data becomes thin, selective bottom-up checks are applied, such as sampled program values, shipment timing from contract awards, and an average selling price range built from configuration clues and upgrade content.
Key inputs that regularly move the totals include the active versus passive ESA mix, retrofit versus new-build share, radar unit counts per platform (for example, fighters and naval combatants), delivery and upgrade cadence tied to modernization plans, and module intensity proxies that track how much hardware is refreshed. For forecasting, scenario analysis is used so that procurement delays, budget reallocations, and accelerated replacement cycles can be stress-tested before the final growth path is set. When a platform or region lacks transparent program disclosure, we fill gaps using comparable fleet sizes and procurement patterns, and then re-check the implied spend against public budget lines.
Data Validation & Update Cycle
Validation is handled through multi-step checks where model outputs are compared against independent signals like annual procurement spending, major contract award totals, and platform delivery schedules, and then reviewed for year-to-year spikes that do not match program timelines. We also run currency and inflation consistency checks so that pricing drift does not get mistaken for real unit growth.
Before sign-off, assumptions that materially change the totals are re-tested through follow-up calls, and the full workbook is peer-reviewed to catch formula errors and scope leakage. The report is refreshed annually, and interim updates are made when major awards, cancellations, or export approvals materially shift the expected delivery profile. Right before delivery, a final analyst pass is done so clients receive the latest updated view.
Mordor Intelligence's Electronically Scanned Array Radar Market Size Measured Against Other Published Estimates
Published market sizes for ESA radars often differ because each publisher sets its own definition for what counts as ESA content, and because program visibility varies across countries and platforms. Differences also come from how upgrade revenue is handled, whether values are stated in nominal or constant dollars, and how currency timing is applied.
Software-only radar upgrades sit outside Mordor Intelligence's scope, which is one reason the 2025 total can look higher or lower than estimates that blend in signal processing refresh work without new transmit/receive hardware. Other gaps usually come from mixing broader electronically scanned arrays that include non-radar applications, or from using aggressive program acceleration assumptions that are not supported by budget documents and delivery schedules.
Benchmark comparison
| Source | Market Size | Gaps in Research Methodology |
|---|---|---|
| Mordor Intelligence | USD 10.29 B (2025) | |
| Industry Research Publisher A | USD 8.70 B (2024) | Uses a broader electronically scanned array market framing, which can blend radar and adjacent non-radar array uses, and the base year is different, making direct comparison sensitive to defense procurement timing. |
| Industry Research Publisher B | USD 6.17 B (2025) | Appears to focus on a narrower radar subset by application (air, land, sea) and may exclude space and HAPS-related deployments, which can reduce the captured revenue pool in years with active program awards. |
The table shows that most of the spread is explained by scope width and what gets counted as revenue-bearing hardware versus broader array activity. When the same year, platform coverage, and upgrade rules are aligned, the range typically tightens, and the remaining difference is mostly due to procurement timing and currency conversion choices that move year-specific totals.
