The aerospace and defense propulsion system market size has grown strongly in recent years. It will grow from $268.08 billion in 2024 to $287.21 billion in 2025 at a compound annual growth rate (CAGR) of 7.1%. The growth observed in the historic period can be attributed to the rising demand for commercial air travel, ongoing military modernization initiatives, increased use of unmanned aerial vehicles, the expansion of satellite launch activities, and growing government defense budgets.

The aerospace and defense propulsion system market size is expected to see strong growth in the next few years. It will grow to $374.56 billion in 2029 at a compound annual growth rate (CAGR) of 6.9%. The projected growth in the forecast period is driven by factors such as a greater emphasis on sustainable aviation fuels, increased demand for space exploration missions, the expansion of electric aircraft development, rising defense spending on next-generation aircraft, and growing interest in reusable launch systems. Key trends for the forecast period include advancements in electric propulsion technology, rapid innovations in hybrid propulsion systems, developments in supersonic travel technologies, growing research and development in green propulsion, and ongoing advancements in propulsion materials.

The expansion of commercial air travel is anticipated to drive the growth of the aerospace and defense propulsion system market in the coming years. Commercial air travel involves the transport of passengers or cargo for a fee, typically operated by airline companies. This sector has seen significant growth, largely driven by economic development, which increases disposable income, enabling more individuals to afford both business and leisure flights. As commercial air travel grows, so does the demand for efficient and sustainable propulsion systems in the aerospace and defense sectors. Airlines are focused on expanding capacity while minimizing emissions, spurring the development of cutting-edge, environmentally friendly propulsion technologies. For example, in March 2023, the Bureau of Transportation Statistics, a U.S.-based government agency, reported that U.S. airlines carried 853 million passengers in 2022, a 30% increase from 658 million passengers in 2021. Therefore, the continued expansion of commercial air travel is driving the growth of the aerospace and defense propulsion system market.

Key players in the aerospace and defense propulsion system market are also prioritizing the development of advanced technologies, such as high-voltage power distribution components, to support the electrification of next-generation aircraft and defense platforms. These components manage and distribute electrical power within aircraft or spacecraft, ensuring their safe and efficient operation by regulating power flow and safeguarding sensitive systems in electric propulsion systems. For instance, in October 2024, Collins Aerospace, a U.S.-based aerospace technology provider, completed the prototype development of a solid-state power controller and power distribution panel for the Clean Aviation SWITCH project. These megawatt-class components, produced in Germany, are designed to manage the high-voltage electricity required for next-generation hybrid-electric aircraft propulsion systems. The prototypes will undergo system integration testing at Collins' electric power systems lab in Rockford, Illinois, supporting the SWITCH project's goal to achieve significant CO₂ reductions in short- to medium-range aircraft through innovative hybrid-electric technologies.

In January 2025, MBDA Systems, a France-based missile manufacturer, acquired a 50% stake in Roxel, a French company specializing in solid propulsion systems for tactical and cruise missiles. The acquisition, for an undisclosed amount, is intended to enhance MBDA's control over its propulsion supply chain, accelerate innovation in solid propulsion technologies, and optimize industrial cycles to meet the increasing global demand for tactical missile systems.

An aerospace and defense propulsion system refers to the collection of technologies, machinery, and components designed to generate thrust, allowing aircraft, spacecraft, missiles, and other defense vehicles to move through air or space. These systems are essential for achieving lift-off, sustained flight, maneuverability, and overall mission success in both civilian and military settings.

The primary types of aerospace and defense propulsion systems are air-breathing and non-air-breathing. Air-breathing propulsion systems rely on atmospheric oxygen for combustion, making them highly efficient for high-speed aircraft and missiles operating at various speeds and altitudes. These systems are used in a variety of applications, including missiles, aircraft, spacecraft, and unmanned aerial vehicles (UAVs), serving end-users such as commercial entities, government agencies, and the military.
