Between the 18th to the early 20th centuries, from the Battle of Trafalgar to World War II, the British Royal Navy for the most part had undisputed power over the world’s oceans and controlled the seas. This enabled Britain and its allies to move supplies and troops with more ease during times of war, while the enemy could not. Post World War II, the United States Navy overtook Britain in both size and power, becoming the dominant force on the water. 

The era of massive navies controlling the seas, trade, and borders, has ended. According to the U.S. Naval Institute, the U.S. no longer has command of the high seas. Due to the rise of the Chinese Navy and the return of the Russian Navy, serious challenges have arisen, and although America has a global naval influence, it has been unable to exert local sea control.  

Today, technology has advanced to the point that a single advanced ship can dominate an engagement against older vessels. An American Zumwalt-class destroyer has the potential to be armed with 80 of a variety of highly advanced cruise, anti-submarine, and anti-ship missiles, and are currently being refitted with hypersonic missiles. But while technological advancement is important, there is still strength in numbers. For countries with widespread interests, it’s important to have plenty of naval vessels. 

24/7 Wall St. reviewed the defense statistics website GlobalFirepower’s 2023 naval forces database with information about 145 countries’ militaries to determine the nation with the largest navy in the world. We ranked countries according to the number of naval vessels in their military, starting at 150 vessels, and included the number of vessels in four classes of vessels. Data on notable ships came mostly from Military Factory, among other sources. Data on total military spending and military spending as a percentage of gross domestic product came from Stockholm International Peace Research Institute’s Military Expenditure Database.

Following a relentless military buildup, China now has the world’s largest navy. This is cause for concern for Taiwan, which is about 100 miles east across the Taiwan Strait from the Chinese mainland. China has more submarines, destroyers, frigates, and corvettes than any other nation. Russia, traditionally a land power that has historically sought ice-free ports, is second in total vessels. 

The United States may not be the largest navy in the world, coming in at number four, but they are buttressed by 11 aircraft carriers, more than any other country. In terms of quality and firepower, the U.S. Navy has no equal in the world. (Here are 11 new warships that will join the U.S. Navy fleet.)

The United Kingdom’s Royal Navy, once the world’s most powerful navy until World War II, is not even among the top 21 largest navies at sea. This is a big indicator of how times have changed.
