Which EU Country Has the Largest Navy?

Key Takeaways

• Italy has the largest navy in the EU by ship count.
• France has the most tonnage among the 12 EU countries with tonnage data, because its Navy works on every sea and needs large ships for that work.
• Italy’s carrier Cavour does the work of four ships: aircraft carrier, tank carrier, command ship and hospital ship.
• Germany ranks 4th among the 12 countries for tonnage because its Navy needs large ships that can stay at sea longer and farther from home in the North Atlantic.
• Finland ranks 6th for naval assets but near the bottom for tonnage because the shallow, crowded Baltic Sea favors smaller ships and mines.
• A navy’s fleet follows its job, so navies that work far from home have more tonnage than navies that work in a small, shallow sea.

Italy Has the Largest EU Navy by Ship Count, While France Leads by Tonnage

Italy has the largest navy in the EU by ship count. It lists 285 naval assets.

Naval assets are all the warships, submarines, and support vessels a navy operates. A small patrol boat and an aircraft carrier each count as one.

Tonnage adds up the size of those navy vessels in tonnes. This gives larger ships, such as aircraft carriers, more weight in the ranking than smaller patrol boats.

France has the largest navy in the EU by tonnage, with 487,471 tonnes among the 12 countries with available data. However, it ranks fifth by ship count, with 166 naval assets.

France’s Navy operates across the world’s oceans throughout the year, sending ships far from home for extended missions. These operations require large vessels capable of carrying aircraft, troops, and equipment.

As of December 31, 2024, France’s Navy operated one aircraft carrier, three amphibious helicopter carriers, and four nuclear ballistic missile submarines. Each type of vessel serves a different purpose:

• Aircraft carrier: Allows France to deploy military aircraft and project power far from its territory without relying on foreign air bases.
• Amphibious helicopter carriers: Serve as command centers and platforms for deploying troops and helicopters.
• Nuclear ballistic missile submarines: Support France’s nuclear deterrence strategy, with at least one submarine kept at sea at all times.

These large vessels help explain why France has the EU’s highest naval tonnage despite having fewer naval assets than Italy.

Three other countries also rank differently on ship count and tonnage. Their tonnage ranks are among the 12 countries with a tonnage figure.

• Germany: 9th for naval assets, 4th for tonnage
• Finland: 6th for naval assets, 11th for tonnage
• Sweden: 2nd for naval assets, 10th for tonnage

These differences partly reflect the types of missions each navy performs and the waters it operates in.

Similar to France, Germany and Italy use large ships for missions far from home:

• Italy: Its Navy needs ships for missions around the world. Its carrier Cavour works as an aircraft carrier, tank carrier, command ship, and hospital ship.
• Germany: Its Navy defends Germany and its allies in NATO (the Western military alliance), mainly in the North Atlantic. Large warships suit that work because they can stay at sea longer and farther from home bases.

Finland faces different naval conditions. The Baltic Sea is small, shallow, and crowded with commercial sh

Finland also has a large archipelago, a group of islands along its coast. These islands provide cover for smaller naval vessels, making them harder to detect.

Sea mines and missiles play an important role in Finland’s coastal defense. Its mine warfare vessels are responsible for laying and clearing naval mines, while smaller vessels support operations in the coastal waters.

This environment favors a fleet of smaller vessels rather than a few large warships.

Sweden’s Navy also operates in the Baltic Sea, where coastal conditions and geography influence naval operations.

A navy’s fleet is shaped by the work it needs to do. Countries that operate far from home generally need larger ships with greater range and endurance. Countries operating in smaller, shallower waters can rely more on smaller vessels suited to coastal operations.
