Radar Systems - Airborne: Market Size & Forecast 2026

The global airborne radar systems market reached approximately USD 18.5 billion in 2025 (base year), growing at a 5.8 percent CAGR through 2032 to reach roughly USD 27.5 billion. The market sits in a structurally tight configuration: AESA architecture adoption is accelerating across fighter and UAS platforms, GaN-on-SiC wafer supply remains constrained by limited epitaxial foundry capacity, and ITAR Category XI export controls create friction for international buyers seeking non-US alternatives. A reference AESA radar system integrating a 1,024-element T/R module array with embedded signal processor ships at approximately USD 450,000 per unit, with AESA semiconductors (GaN/SiGe) representing the single largest cost bucket at 32 percent of finished cost. > **Analyst Take.** The consensus 6-7 percent CAGR band for this market runs ahead of what the GaN substrate supply chain can actually d
