An Infrared Search & Track (IRST) System is a passive electro-optical sensing technology that detects and tracks targets by capturing the infrared energy they emit rather than relying on radar transmissions. These systems are extensively deployed in fighter aircraft, naval warships, and advanced defense platforms to enhance situational awareness and stealth capabilities. The increasing focus on modernizing defense infrastructure and countering low-observable threats continues to fuel the growth of the Infrared Search & Track (IRST) System Market.

According to the Business Market Insights The Infrared Search & Track (IRST) System Market size is expected to reach US$ 10.80 Billion by 2033 from US$ 6.90 Billion in 2025. The market is estimated to record a CAGR of 5.70% from 2026 to 2033.

Market Overview

The global Infrared Search & Track (IRST) System Market is experiencing consistent growth as defense organizations prioritize advanced surveillance, target acquisition, and situational awareness capabilities. Unlike conventional radar systems, IRST systems operate passively, making them difficult to detect while effectively identifying stealth aircraft, cruise missiles, drones, and naval threats.
