Military Gas Turbine Market Report 2025

The military gas turbine market size has grown strongly in recent years. It will grow from $11.75 billion in 2024 to $12.44 billion in 2025 at a compound annual growth rate (CAGR) of 5.9%. The growth during the historic period can be attributed to the rise in global defense expenditures, increased deployment of fighter jets in conflict regions, growing investments in military modernization efforts, expanded use of unmanned aerial vehicles (UAVs), and a heightened emphasis on indigenous defense manufacturing.

The military gas turbine market size is expected to see strong growth in the next few years. It will grow to $15.43 billion in 2029 at a compound annual growth rate (CAGR) of 5.5%. The growth in the forecast period can be attributed to the increasing adoption of next-generation stealth aircraft, rising demand for hybrid-electric propulsion systems, a stronger focus on fuel-efficient turbine technologies, expanding implementation of AI-integrated turbine control systems, and growing investments in hypersonic and space defense platforms. Key trends anticipated during this period include advancements in hybrid-electric propulsion, the development of advanced cooling solutions for high-performance turbines, the creation of compact turbofan engines for UAVs, innovations in additive manufacturing for turbine parts, and the application of advanced digital twin technology for predictive maintenance.

The rising defense budgets are expected to drive the growth of the military gas turbine market in the coming years. Defense expenditure refers to the financial resources allocated by governments to maintain and develop armed forces and ensure national security. The increase in defense spending is largely driven by growing geopolitical tensions, as global conflicts, territorial disputes, and power rivalries push countries to improve their military preparedness and deterrence capabilities. With larger budgets, governments can invest in advanced aircraft, naval ships, and land-based systems that rely on gas turbines for power and propulsion. These engines are preferred for their high performance, reliability, and ability to function effectively in challenging conditions. For example, in January 2025, the Department of National Defense in Canada reported that the country's defense budget is projected to rise to 1.37% of GDP in 2024-25 from 1.31% in 2023-24. Furthermore, 18.6% of the budget is allocated to major equipment purchases, an increase from 14.8% the previous year. Thus, rising defense expenditure is contributing to the growth of the military gas turbine market.

Key companies in the military gas turbine sector are working on the development of innovative technologies, such as micro turbojet engines, to boost propulsion efficiency, versatility, and adaptability across modern defense platforms. A micro turbojet engine is a compact jet engine that generates thrust by compressing air, mixing it with fuel, igniting the mixture, and expelling the high-speed exhaust through a nozzle. For instance, in February 2024, RVMT, an aerospace company based in India, introduced the INDRA RV25: 240N, the country’s first domestically developed micro turbojet engine. The engine produces a thrust of 240 Newtons (approximately 25 kg) and has been fully designed and manufactured in India with support from premier institutions such as IIT-Hyderabad. It features a compact structure, a high thrust-to-weight ratio, and precision-engineered parts. The INDRA RV25 is particularly suited for unmanned aerial vehicles (UAVs), target drones, and loitering munitions.

In May 2025, EthosEnergy, a U.S.-based provider of rotating equipment services and solutions for industries including power generation, oil and gas, aerospace, and manufacturing, acquired Turbine Services, Ltd. (TSL) for an undisclosed sum. This acquisition expands EthosEnergy’s portfolio of turbine products and enhances its capabilities in delivering services for critical rotating equipment. Turbine Services, Ltd. is a U.S.-based company that manufactures and distributes aftermarket parts for heavy-duty gas and steam turbines.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

The sharp hike in U.S. tariffs and the associated trade disputes in spring 2025 are notably impacting the aerospace and defense sector by raising costs for titanium, carbon fiber composites, and avionics materials largely sourced from global suppliers. Defense contractors, locked into fixed-price government contracts, absorb these added costs, while commercial aerospace firms face airline pushback on higher aircraft prices. Delays in component shipments due to customs bottlenecks further disrupt tight production schedules for jets and satellites. The industry is responding by stockpiling critical materials, seeking waivers for defense-related imports, and collaborating with allied nations to diversify supply chain.

Military gas turbines are engines designed to power military aircraft, ships, and vehicles. They function by compressing air, mixing it with fuel, igniting the mixture, and using the resulting high-temperature, high-pressure exhaust gases to spin a turbine. These turbines convert the chemical energy from fuel into high-speed mechanical energy, delivering the performance, reliability, and quick acceleration required for combat operations.

The primary types of military gas turbines include turbojet engines, turboprop engines, turbofan engines, and turboshaft engines. Turbojet engines are a kind of gas turbine that produces thrust by discharging jet exhaust at high velocity. These engines are applied across different categories of gas turbines such as micro, heavy-duty, and light-duty turbines. Key components include the compressor, combustor, gas turbine rotor, generator, and control systems. Military gas turbines are used in various platforms including fighter jets, helicopters, unmanned aerial vehicles (UAVs), naval vessels, and others. They serve a range of end users such as defense agencies, original equipment manufacturers (OEMs), and private military contractors.
