Aerospace and Military Auxiliary Power Unit (APU) Market by Application (Commercial Aircraft, Military Aircraft, Military Land Vehicle, Rotary Copter), and Region 2025-2033

The global aerospace and military auxiliary power unit (APU) market size reached USD 4.2 Billion in 2024. Looking forward, IMARC Group expects the market to reach USD 5.6 Billion by 2033, exhibiting a growth rate (CAGR) of 3.15% during 2025-2033. The growing demand for fuel-efficient solutions to minimize fuel consumption, increasing development of electric aircraft to reduce carbon emissions, and rising requirement for additional power in aircraft represent some of the key factors driving the market.

An aerospace and military auxiliary power unit (APU) is a device that provides electrical power to the electrical systems on an aircraft. It relies on the aircraft battery to operate and is generally located in the tail cone, engine nacelle, or wheel well in different aircraft types. It allows an aircraft to operate autonomously without the need for ground support equipment, such as a ground power unit, an external air-conditioning unit, or a high-pressure air start cart. It aids in offering pneumatic energy until the aircraft reaches a certain height. Besides this, it assists in providing reliable performance and reducing fuel consumption and maintenance costs of aircraft. As it is beneficial in emergency situations like engine failure to provide electrical power, the demand for aerospace and military APU is rising across the globe.

Aerospace and Military Auxiliary Power Unit (APU) Market Trends:

At present, the rising demand for APUs due to the inflating income levels and consequently increasing number of people traveling to different places represents one of the primary factors contributing to the growth of the market. Apart from this, the growing utilization of APUs in the electric aircraft to reduce carbon emissions is offering a favorable market outlook. Additionally, their rising adoption for additional power in aircraft is impelling the growth of the market. Besides this, the growing employment of APUs in aircraft due to the increasing number of cargo operations that carry goods efficiently from one place to another is positively influencing the market. In addition, the rising need to reduce fuel consumption in the aerospace and military sector is bolstering the growth of the market. Moreover, the increasing deployment of APUs in military aviation due to the rising defense expenditure, along with the upgradation of old military aircraft, is offering lucrative growth opportunities to industry players. In line with this, the increasing demand for military aircraft on account of the rising number of terrorist activities around the world is supporting the market growth. Furthermore, key players are introducing low-noise APUs for silent military operations and reducing noise pollution, which is strengthening the growth of the market.
