Military Aircraft Engines Global Market Report 2025

The military aircraft engines market size has grown steadily in recent years. It will grow from $17.78 billion in 2024 to $18.4 billion in 2025 at a compound annual growth rate (CAGR) of 3.5%. The growth in the historic period can be attributed to growing demand for unmanned aerial vehicles, rising adoption of stealth and supersonic aircraft, increasing demand for multi-role combat aircraft, high environmental and regulatory pressures, and a growing focus on fuel efficiency and environmental sustainability.

The military aircraft engines market size is expected to see steady growth in the next few years. It will grow to $21.11 billion in 2029 at a compound annual growth rate (CAGR) of 3.5%. The growth in the forecast period can be attributed to increasing defense budgets, a growing need for advanced propulsion technologies, increasing government contracts and support, rising military modernization programs, and increasing geopolitical tensions. Major trends in the forecast period include advancements in engine materials and coatings, technological progress in thrust vectoring systems, the development of adaptive cycle engines, the integration of digital engine control systems, and the development of hybrid-electric propulsion systems.

The forecast of 3.5% growth over the next five years reflects a modest reduction of 0.3% from the previous estimate for this market.This reduction is primarily due to the impact of tariffs between the US and other countries. This is likely to directly affect the US through tariffs on single-crystal turbine blades from the UK and Japan, increasing costs for next-generation fighter propulsion.The effect will also be felt more widely due to reciprocal tariffs and the negative effect on the global economy and trade due to increased trade tensions and restrictions.

The increasing defense budgets are expected to drive the growth of the military aircraft engines market. Defense budgets refer to the financial allocations made by governments to support military and defense activities, including personnel, equipment, and operational expenses. These budgets are rising due to growing geopolitical tensions, prompting nations to enhance military readiness and modernize their defense capabilities. Higher defense spending often leads to more orders for advanced fighter jets, transport aircraft, drones, and helicopters, all of which require powerful, reliable engines. This surge in demand drives the need for both new engines and replacement parts. For instance, in April 2025, the Stockholm International Peace Research Institute, a Sweden-based independent international organization, reported that U.S. military expenditure reached \$997 billion in 2024, marking a 5.7% increase from 2023. As a result, the rise in defense budgets is contributing to the growth of the military aircraft engines market.

Companies in the military aircraft engines market are focusing on developing innovative technologies such as supersonic ramjet engines to improve speed, maneuverability, and mission effectiveness in next-generation combat aircraft. A supersonic ramjet engine, or scramjet, is an air-breathing jet engine that allows combustion at supersonic speeds, enabling aircraft to achieve hypersonic speeds above Mach 5. For example, in February 2025, Hyprix, an India-based defense and aerospace company, unveiled Tezz, a liquid-fueled engine designed for high-speed military applications, including next-generation missiles and advanced aerial platforms. Developed in just five months, Tezz highlights India’s private sector capabilities in advanced propulsion technology and aligns with the country's strategic goals for defense self-reliance. The successful development and testing of Tezz not only demonstrate Hyprix’s technological expertise but also signify a broader shift toward indigenous solutions in high-speed aviation and defense systems.

In April 2024, Royal Air Maroc, a Morocco-based airline, entered into a partnership with Safran S.A. to improve its aircraft engine maintenance services and optimize fleet performance. Through this partnership, Royal Air Maroc aims to boost fleet efficiency and reliability with advanced engine maintenance solutions, lower operational costs, and reinforce safety and performance standards by leveraging Safran’s technical expertise. Safran S.A., a France-based company, specializes in the design, development, and manufacturing of engines, equipment, and systems for aircraft, helicopters, and space vehicles.

Military aircraft engines are propulsion systems specifically designed and built to power various military aircraft, such as fighter jets, transport planes, and surveillance aircraft. These engines are engineered for high performance, durability, and reliability, especially under extreme operational conditions such as combat and tactical missions.

The main types of military aircraft engines include turbofan engines, turboprop engines, turbojet engines, and turboshaft engines. Turbofan engines, a popular jet engine variant, use a large front fan to enhance efficiency by mixing bypassed air with traditional jet thrust. Key components of these engines include the compressor, turbine, combustion chamber, and afterburner. Military aircraft engine technologies range from conventional and hybrid systems to emerging electric engines. These engines are utilized in various applications, such as fighter jets, transport aircraft, helicopters, bombers, reconnaissance planes, tanker aircraft, and unmanned aerial vehicles (UAVs).

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 increase in U.S. tariffs and resulting trade disputes in spring 2025 are significantly affecting the aerospace and defense sector. Prices for key materials such as titanium, carbon fiber composites, and avionics primarily sourced from international suppliers have surged. Defense contractors, constrained by fixed-price government contracts, are forced to absorb these rising costs. Meanwhile, commercial aerospace companies are encountering resistance from airlines over increased aircraft prices. In addition, customs delays are disrupting already tight production timelines for jets and satellites. In response, the industry is stockpiling essential materials, pursuing import waivers for defense-related goods, and working with allied nations to diversify supply chains.
