While humanity has its feet firmly on solid ground, the world’s oceans have always played a crucial role in global power. Covering around 71% of the Earth’s surface, seas and waterways have been fought over for thousands of years, from ancient trade routes to modern shipping lanes that keep the global economy moving.
To protect these vital interests, many countries have built enormous naval forces packed with warships, submarines and aircraft carriers. Some fleets focus on sheer size, while others rely on advanced technology and global reach. Revealed below are the 11 biggest navies in the world, based on their total naval assets in 2024, according to the World Population Review. It warns, however, that the size of a country’s navy is only one factor in its ability to effectively conduct warfare. Additional factors include the level of training given to soldiers, the age and condition of the included vessels and the effectiveness of strategic command.
11. Finland – 246 naval assets
Finland’s navy operates 246 vessels, the vast majority of which are small patrol boats, mine warfare ships and support craft designed for operations in the Baltic Sea. Its fleet is built around defending narrow coastal waters and chokepoints rather than blue-water deployments.
Finland does not operate any aircraft or helicopter carriers. Instead, it relies on shore-based air power and fast, flexible surface units to protect its maritime borders.

10. Sri Lanka – 270 naval assets
Sri Lanka fields 270 naval assets, making it one of the larger fleets in South Asia by vessel count. The navy is dominated by fast attack craft and patrol boats used for coastal security, counter-smuggling and anti-piracy operations.
It does not operate any aircraft or helicopter carriers, with its maritime strategy firmly focused on protecting territorial waters rather than projecting power beyond the region.

9. Thailand – 293 naval assets
Thailand’s navy consists of 293 vessels, most of which are smaller patrol and coastal defence ships. While Thailand once operated a light carrier in a limited role, it currently has no aircraft or helicopter carriers in active service.
The fleet supports national security, disaster relief and regional stability rather than sustained overseas operations.
