Key Takeaways

• Northern Europe prioritises air defence. Sweden (42.4% fighter fleet share out of total aircraft) and Finland (32.7%) have some of the highest fighter shares, reflecting a focus on territorial defence and proximity to Russia.
• Southern Europe combines scale with combat capability. Greece (178 fighters, 31.8%) and Spain (30.9%) maintain large fighter fleets due to regional tensions and broader geographic responsibilities.
• Larger countries often operate more diversified air forces. France (223 fighters, 22.9%), Germany (22.3%), and Italy (12.3%) balance fighter aircraft with transport, surveillance, and support roles.
• Small countries like Belgium (42.3%) maintain high fighter shares while relying on NATO allies for logistics and support.
• Air force structure reflects more than size. Across the EU, differences in fighter fleets show how countries balance geography, security needs, and alliance cooperation.

Air power plays a central role in how European NATO members protect their airspace and respond to threats.

Within that, fighter aircraft are the core combat component. They are used for air defence, interception, and multi-role missions. The size of a country’s fighter fleet, and how large it is compared to its total aircraft. helps show how much emphasis is placed on combat air power.

Countries in Northern Europe stand out for both their fighter share and structure.

• Sweden operates 73 fighters out of 172 aircraft (42.4%)
• Finland has 53 out of 162 (32.7%)

These are among the highest shares in the EU.

This reflects geography and security priorities. Both countries are located close to Russia and have historically focused on territorial defence and rapid response. Maintaining a relatively large fighter fleet allows them to monitor and defend their airspace with limited reliance on external support.

In Southern Europe, several countries combine larger overall air forces with a relatively strong fighter presence.

• Greece operates 178 fighters out of 560 aircraft (31.8%), one of the largest fighter fleets in the EU.
• Spain has 136 out of 440 (30.9%)

These levels reflect the different security situations in the region, such as:

• Greece keeps a strong air combat capability because of long‑standing tensions in the Eastern Mediterranean and its role in NATO’s southern‑flank air defence.
• Spain also needs a large number of combat aircraft because it has to cover both its mainland and its islands. It also helps NATO patrol the skies and watch over the seas in the western Mediterranean and off the Atlantic coast.

Aside from the regional differences between northern and southern Europe, the scale of each air force also reflects distinct priorities and functions within the EU and NATO. 

Larger member states tend to operate more diversified air forces, as they take on broader responsibilities. These include not only air defence, but also international missions, logistics, and long-range operations.

• France: 223 fighters out of 974 aircraft (22.9%)
• Germany: 127 out of 569 (22.3%)
• Italy: 88 out of 714 (12.3%)

These countries operate the largest air forces in the EU, as well as some of the largest fighter fleets. At the same time, their fleets include substantial numbers of transport, surveillance, tanker, and support aircraft.

Meanwhile, smaller air forces (e.g., Belgium: 44 fighters out of 104 aircraft) place greater emphasis on core combat capabilities, while relying on allies, especially NATO, for many of the transport, logistics, and broader support functions.

Across the EU, differences in fighter fleets reflect how countries organise and prioritise their air power.

Beyond size alone, the structure of an air force shows how each country approaches security, geography, and cooperation within NATO.

Why Do Some EU Countries Not Have Fighter Fleets?

Some EU countries operate few or no fighter aircraft. This includes Ireland, the Baltic states, and Luxembourg.

Instead, they rely on shared defence arrangements such as NATO air‑policing missions. In these cases, air defence is provided collectively, with other NATO members deploying fighters to patrol their airspace, rather than through national fighter fleets.
