The global aerospace and defence radar market size is expected to be valued at US$ 14.8 billion in 2026 and projected to reach US$ 23.3 billion by 2033, growing at a CAGR of 6.7% between 2026 and 2033.

Heightened geopolitical instability and the worldwide pursuit of layered air-defence capability are the principal forces propelling this market. Record defence outlays, with global military expenditure climbing to US$ 2,718 billion in 2024 according to SIPRI, are channelling capital toward early-warning, fire-control, and surveillance sensors.

At the same time, the proliferation of low-cost drones and hypersonic threats is forcing nations to refresh ageing radar fleets with Gallium Nitride (GaN)-based active electronically scanned array (AESA) systems, while record civil air-traffic volumes sustain parallel demand for next-generation surveillance infrastructure.

Drivers - Sustained Defence Modernisation Budgets Anchor Radar Procurement

Persistent, multi-year defence modernisation forms the bedrock of radar demand. Global military expenditure reached US$ 2,718 billion in 2024, a real-terms jump of 9.4% reported by the Stockholm International Peace Research Institute (SIPRI), the steepest annual increase since the Cold War. Within NATO, 23 of 32 members met the 2% of GDP spending benchmark in 2024, up from just 6 members in 2021, with much of the uplift directed at integrated air and missile defence.

The U.S. Department of Defense alone requested roughly US$ 849.8 billion for fiscal year 2025. Because radar is foundational to situational awareness, every multi-domain modernisation programme embeds sensor procurement, sustaining a durable, budget-backed pipeline for prime contractors and subsystem suppliers alike.

Contested Airspace and Drone Threats Reshape Sensor Demand

The maturation of uncrewed and hypersonic threats compels states to procure radars able to detect small, fast, low-observable targets. The conflict in Ukraine has shown that swarms of attritable drones can saturate legacy defences, accelerating worldwide investment in counter-unmanned aircraft system (C-UAS) sensing. The U.S. Army has fielded multi-mission radars such as the KuRFS and LTAMDS to close this gap, while European states reinforce eastern-flank surveillance.

According to the European Union Aviation Safety Agency (EASA), drone operations across the bloc continue to multiply, blurring civil-military airspace boundaries. This threat convergence is shifting demand toward software-defined AESA radars that can be re-tasked across air-defence, fire-control, and surveillance roles, lifting per-unit value and replacement frequency.

Restraints - High Development Costs and Protracted Procurement Cycles

Advanced radar programmes carry substantial capital intensity and lengthy timelines that constrain market velocity. Designing a modern GaN-based AESA array demands specialised semiconductor fabrication, secure supply chains, and years of integration testing, often pushing flagship programmes beyond a decade from concept to fielding. Government procurement adds friction through competitive solicitation, legislative appropriation, and rigorous qualification, which can stretch award-to-delivery cycles by several years.

The U.S. Government Accountability Office (GAO) has repeatedly flagged schedule slippage and cost overruns across major defence acquisition programmes. These dynamics raise entry barriers, delay revenue recognition for suppliers, and limit how quickly smaller nations can modernise their radar inventories.

Export Controls and Technology-Transfer Restrictions

Stringent export-control regimes restrain cross-border commerce in sensitive radar technology. In the United States, the International Traffic in Arms Regulations (ITAR) administered by the U.S. Department of State governs transfers of military electronics, while the multilateral Wassenaar Arrangement coordinates controls across 42 participating states. Licensing reviews can delay or block sales of high-end AESA and electronic-warfare-capable radars, particularly to non-allied buyers.

Compliance imposes legal and administrative overhead, and the threat of penalties discourages some vendors from pursuing marginal foreign opportunities. For end-users, these controls narrow supplier choice and can force costly indigenous development, tempering the addressable demand suppliers may lawfully serve.

Opportunities - Gallium Nitride AESA Retrofit and Upgrade Revenue

A vast installed base of mechanically scanned and early gallium-arsenide radars presents a multi-billion-dollar modernisation runway. Defence ministries increasingly favour mid-life upgrades over wholesale replacement, swapping legacy front ends for GaN-based AESA modules that deliver greater range, reliability, and electronic protection at lower lifecycle cost.

The fastest-moving platform niche, mobile and transportable radar systems, projected to advance at a 7% CAGR is especially retrofit-friendly, letting armies upgrade sensors without re-platforming entire batteries. Prime contractors are responding RTX, Lockheed Martin, Thales, and Hensoldt have all introduced scalable GaN building blocks designed for incremental insertion. For suppliers, recurring upgrade contracts and obsolescence-management services offer higher-margin, lower-risk revenue than greenfield development, while giving cost-constrained customers a credible path to capability parity.

Counter-UAS and Space Domain Awareness Programmes

Two emerging mission areas, counter-drone defence and space situational awareness, are set to generate outsized demand. Persistent drone threats have made layered C-UAS a procurement priority for armies, critical-infrastructure operators, and event security, creating a market for compact electronically scanned radars optimised for small-target detection.

In parallel, congestion in orbit is driving investment in ground- and space-based tracking; the U.S. Space Force received roughly US$ 29.4 billion in its fiscal year 2025 request, funding sensors that catalogue debris and satellites. The European Space Agency (ESA) estimates more than 36,500 trackable objects larger than 10 cm now orbit Earth, underscoring the need for advanced radar. Vendors that field dual-use, software-defined sensors spanning terrestrial C-UAS and space-tracking roles can capture demand across both defence and emerging commercial space-safety customers.

Radar Type Insights

Within the radar-type category, Surveillance Radar commands the dominant position with an estimated 28% share in 2026. Its primacy reflects ubiquity: surveillance sensors underpin early-warning, airspace policing, border monitoring, and air-traffic functions, making them the most widely procured class across both military and civil customers. Every layered air-defence architecture begins with wide-area detection, so surveillance radars are acquired in greater volume than specialised fire-control or weather sets.

The shift toward GaN-based AESA long-range surveillance, exemplified by programmes such as Lockheed Martin's TPY-4 and Raytheon's LTAMDS, has further reinforced demand by extending detection ranges against low-observable targets. Sustained NATO eastern-flank reinforcement and Indo-Pacific air-defence build-ups ensure surveillance radar retains the largest installed footprint throughout the forecast horizon.

Platform Type Analysis

By platform, Ground-Based Radar Systems lead decisively with a 42% share in 2026. Terrestrial radars dominate because they form the persistent backbone of national air-defence, missile-warning, and border-surveillance networks, operating continuously without the size, weight, and power limits of airborne or naval hosts. Their versatility spans fixed strategic early-warning arrays to deployable tactical sets, and they are the natural home for the largest, most powerful apertures.

Heightened missile and drone threats have spurred orders for systems such as the U.S. Army's LTAMDS and Lockheed Martin's TPY-4, while European states reinforce ground-based air surveillance along NATO's eastern frontier. Because ground installations also anchor integrated command-and-control nodes, they attract the bulk of sustainment and upgrade spending, cementing their leadership across the forecast period.

Application Analysis

Among applications, airspace monitoring & surveillance holds a foremost position with roughly a 25% share in 2026. The dominance stems from dual demand: militaries require continuous wide-area air pictures for sovereignty enforcement, while civil authorities depend on surveillance radar to manage record air-traffic volumes.

The International Air Transport Association (IATA) reported global air travel surpassing pre-pandemic levels, intensifying the need for modern primary and secondary surveillance radar at airports and en-route centres. On the defence side, contested airspace over Eastern Europe and the Indo-Pacific has pushed nations to thicken early-warning coverage. Because airspace surveillance is a prerequisite for downstream missions such as interception and fire-control, it consistently attracts the broadest procurement base, sustaining its lead over more specialised applications throughout the outlook.
