Electronically Scanned Array Radar Market: Market Size & Forecast 2026

Electronically Scanned Array radar systems use arrays of transmit/receive modules to steer radio beams electronically without physical movement, offering faster scanning, multi-function capability, and improved reliability compared to traditional mechanically scanned radars. The market comprises primarily defense applications including fighter aircraft, naval vessels, ground-based air defense systems, and airborne early warning platforms, alongside civilian uses in air traffic control and meteorology.

• •Market valued at $17.22 billion globally in 2025
• •Technology split between Active (AESA) and Passive (PESA) architectures
• •Applications span military aviation, naval warfare, ground-based defense, and civilian air traffic management

The primary driver remains global military modernization initiatives, with nations upgrading aging radar systems on fighter jets, naval vessels, and ground-based air defense networks. AESA technology adoption continues to expand as armed forces seek enhanced electronic warfare resistance, multi-target tracking, and simultaneous air-to-air and air-to-ground modes. Budget constraints in many Western nations have tempered procurement volumes, keeping growth near flat as replacement cycles extend and technology insertion occurs gradually.

• •Military platform modernization programs across NATO and Asia-Pacific nations
• •Shift toward AESA architecture for superior performance and reliability
• •Increasing demand for counter-drone systems and integrated air defense networks

The market divides primarily between AESA systems, which command premium pricing due to solid-state transmit/receive modules, and PESA systems serving budget-conscious applications and upgrade markets. Platform segments include airborne (fighter aircraft, AWACS, maritime patrol), naval (destroyers, frigates, corvettes), and ground-based systems. North America historically dominates with the largest defense budgets, while Asia-Pacific emerges as the fastest-growing regional segment driven by China, India, Japan, and South Korea military expansions.

• •AESA segment growing share of new production, PESA declining in favor
• •Airborne platforms representing largest application segment
• •Asia-Pacific and Middle East showing strongest investment activity

What are the recent trends and outlook?

The industry is moving toward software-defined radar architectures that allow in-flight waveform adaptation and multi-mission flexibility, reducing the need for specialized radar variants. Gallium nitride semiconductor adoption is improving power efficiency and range capabilities while reducing cooling requirements. Future demand will increasingly emphasize integration with open mission systems architectures to enable cross-platform data sharing and artificial intelligence-assisted target recognition, though near-term growth remains constrained by flat procurement budgets.

• •Gallium nitride enabling smaller, more powerful transmit/receive modules
• •Software-defined waveforms allowing single radar to perform multiple mission functions
• •Convergence with electronic warfare and electronic support measures capabilities
