The 10 Most Powerful Navies in the World, Ranked

Italy's Marina Militare fields one of Europe's most balanced blue-water fleets. Led by the F-35B-capable aircraft carrier ITS Cavour and the 38,000-ton amphibious carrier ITS Trieste, Italy backs its strike groups with Bergamini-class FREMM frigates and ultra-quiet Todaro-class submarines.

Backed by the world's most productive shipyards, the Republic of Korea Navy has rapidly evolved into a formidable blue-water force. Its 11,000-ton Sejong the Great and Jeongjo the Great Aegis destroyers carry up to 128 vertical launch cells alongside 21 diesel-electric attack submarines.

Tasked with defending the world's largest archipelago of 17,000 islands and the strategic Strait of Malacca, the Indonesian Navy (TNI-AL) operates more than 240 active vessels. Its modernizing fleet is spearheaded by Martadinata-class guided-missile frigates and Makassar-class landing docks.

France's Marine Nationale is a true global blue-water navy and the only force outside the United States operating a nuclear-powered catapult aircraft carrier, FS Charles de Gaulle (R91). Combined with three Mistral-class amphibious ships and Suffren-class nuclear submarines, it projects power worldwide.

With centuries of maritime tradition, the British Royal Navy remains a premier global expeditionary force. Its surface fleet is led by two 65,000-ton aircraft carriers - HMS Queen Elizabeth and HMS Prince of Wales - escorted by Type 45 air-defense destroyers and Astute-class nuclear attack submarines.

Technologically second to none in the Indo-Pacific, the Japan Maritime Self-Defense Force operates 36 destroyers - including eight Aegis ballistic-missile-defense ships - and 22 ultra-quiet Taigei and Soryu-class submarines, while converting its two 27,000-ton Izumo-class ships to carry F-35B fighters.

The undisputed maritime guardian of the Indian Ocean, the Indian Navy operates two full carrier strike groups centered on INS Vikramaditya and the domestically built 45,000-ton INS Vikrant. Backed by Visakhapatnam-class stealth destroyers and Arihant-class nuclear submarines, its reach spans the Indo-Pacific.

Divided across the Northern, Pacific, Baltic, and Black Sea fleets, the Russian Navy ranks among the world's top three by total displacement and strategic firepower. Its crown jewel is its undersea fleet of nearly 60 submarines, led by ultra-quiet Yasen-M attack boats and Borei-A ballistic missile submarines.

By sheer number of hulls, China's People's Liberation Army Navy (PLAN) is now the largest naval force on Earth, surpassing 370 battle force ships. Its rapid modernization includes three aircraft carriers - Liaoning, Shandong, and the 80,000-ton electromagnetic-catapult carrier Fujian - plus Type 055 cruisers.

Displacing more than 4.5 million tons across every ocean on Earth, the United States Navy remains the undisputed superpower of the seas. It commands 11 nuclear-powered Nimitz and Gerald R. Ford-class supercarriers, over 70 Arleigh Burke-class Aegis destroyers, and an all-nuclear fleet of 68 submarines.
