Infrared Search and Track System Market to Reach USD 12 Billion by 2032, Growing at 6.18% CAGR

Global demand for infrared search and track (IRST) systems is accelerating as military forces prioritize radar-free surveillance solutions.
Published 03 July 2025

The global Infrared Search and Track System Market is set for steady growth, driven by the rising demand for passive surveillance technologies that enable stealth detection without relying on radar. The market was valued at USD 6.99 billion in 2023 and is expected to grow to USD 7.42 billion in 2024. It is projected to reach USD 12.0 billion by 2032, advancing at a compound annual growth rate (CAGR) of 6.18% during the forecast period from 2025 to 2032.

Infrared Search and Track (IRST) systems allow military forces to detect and track targets by sensing their infrared radiation signatures. These passive systems provide a major tactical advantage by operating silently without emitting signals that can be intercepted by adversaries—making them ideal for modern warfare scenarios involving stealth aircraft and electronic countermeasures.

Market Drivers

One of the key drivers behind the growing adoption of IRST systems is the increasing focus on stealth technologies in global defense operations. As adversaries develop radar-evading aircraft and employ electronic warfare tactics, traditional radar-based detection is often insufficient. IRST provides a complementary and radar-independent solution that enhances situational awareness across all domains—air, sea, and land.

Rising geopolitical tensions and regional conflicts are also fueling defense modernization programs around the world. Countries are actively investing in next-generation aircraft, naval ships, and unmanned platforms equipped with infrared-based tracking and surveillance systems. These systems offer day-and-night operability and are highly effective in contested and cluttered environments.

Another critical factor is the growing need for non-invasive and energy-efficient sensor systems. IRST platforms consume less power compared to active sensors and offer reliable performance in electronically degraded environments. As militaries prioritize lighter, modular, and cost-effective solutions, IRST systems are being deployed across fighter jets, surface vessels, submarines, and drones.

Market Outlook (2024–2032)

The Infrared Search and Track System Market is projected to grow from USD 7.42 billion in 2024 to USD 12.0 billion by 2032. This growth reflects a solid CAGR of 6.18% and underscores the increasing relevance of IRST solutions in the future of defense surveillance.

With advancements in artificial intelligence (AI), machine learning (ML), and sensor fusion, IRST systems are becoming more sophisticated and accurate. AI-enhanced systems can differentiate between real threats and false positives, reduce operator workload, and facilitate faster target acquisition. These innovations are critical in high-speed combat environments where rapid decision-making can determine mission success.

Future IRST technologies will also support multi-domain operations by integrating with existing radar, sonar, and electronic warfare systems. The shift toward network-centric warfare will increase demand for systems that can share and receive real-time data across multiple platforms, forming a more comprehensive defense perimeter.

Additionally, the miniaturization of components and improvements in thermal imaging are opening new opportunities for IRST deployment in unmanned systems such as UAVs and autonomous maritime vehicles. These applications will further expand the market scope beyond traditional aircraft and warship installations.

Regional Insights
