The aerospace and defense thermal management systems market size has grown strongly in recent years. It will grow from $24.35 billion in 2025 to $26.26 billion in 2026 at a compound annual growth rate (CAGR) of 7.8%. The growth in the historic period can be attributed to increasing demand for advanced cooling solutions, growing adoption of unmanned aerial vehicles, rising need for efficient engine thermal management, expansion of avionics and electronics systems, and growing military modernization programs.

The aerospace and defense thermal management systems market size is expected to see strong growth in the next few years. It will grow to $35.09 billion in 2030 at a compound annual growth rate (CAGR) of 7.5%. The growth in the forecast period can be attributed to increasing focus on energy-efficient thermal systems, growing integration of thermal management with power and propulsion systems, rising investments in r&d for innovative materials, expansion of space and satellite programs, and growing demand for lightweight and compact thermal solutions. Major trends in the forecast period include advancements in phase-change and two-phase cooling technologies, innovations in thermal interface materials, developments in smart and adaptive thermal control systems, research and development in hybrid and integrated thermal solutions, and increasing use of predictive thermal management software.

The increasing complexity and heat production of modern avionics, radar, and electronic warfare systems are expected to drive the expansion of the aerospace and defense thermal management systems sector in the coming years. This increase in complexity and heat production refers to the higher levels of waste heat generated by high-power, high-density electronic and propulsion systems in contemporary aerospace and defense platforms, which necessitate engineered solutions to regulate, dissipate, and control temperature to ensure performance, reliability, and safety. The growth in heat generation of advanced avionics, radar, and electronic warfare systems is attributed to the integration of higher-power processors, megawatt-level electrified aircraft propulsion systems, sophisticated radar modules, and next-generation electronic warfare suites that operate at much greater power levels than legacy systems. Aerospace and defense thermal management systems assist in controlling the heat produced by advanced avionics, radar, and electronic warfare systems by enabling early and efficient removal of waste heat, maintaining safe operating temperatures, and ensuring reliable functioning of high-performance electronics under extreme conditions. For example, in April 2025, according to the National Aeronautics and Space Administration (NASA), a US-based government space agency, future electrified aircraft concepts such as NASA's STARC-ABL can generate between 600 kilowatts (kW) and 6 megawatts (MW) of heat, while other hybrid-electric aircraft concepts can produce 200 kW to 1 MW of heat, reflecting significantly higher thermal loads compared to conventional systems. Consequently, the growing complexity and heat generation of advanced avionics, radar, and electronic warfare systems are fueling the growth of the aerospace and defense thermal management systems sector.

Major companies in the aerospace and defense thermal management systems sector are prioritizing the development of cutting-edge technologies, such as pumped two-phase architecture, to enable precise temperature control for high-performance avionics, propulsion units, and space systems. Pumped two-phase architecture involves a thermal management approach where a working fluid circulates through linked liquid and vapor phases via active pumping, allowing highly efficient heat absorption and dissipation over broad operational ranges. This is especially vital in aerospace and defense applications, where maintaining thermal stability is essential for system performance and reliability. For example, in June 2023, Intergalactic Aerospace Corporation, a US-based developer of advanced space propulsion and spacecraft systems, introduced the GS1-EV Eagle5, the first orbital delivery spacecraft to integrate pumped two-phase architecture for thermal regulation. This system employs actively pumped two-phase loops to manage heat from onboard electronics, power systems, and environmental loads throughout all mission phases, ensuring components operate within optimal temperature limits without incurring excessive mass or power costs.
