What is the biggest warship ever built?

The United States Navy’s Nimitz-Class nuclear powered aircraft carriers are the biggest warships ever built. Over 300 metres long, and displacing in excess of 100,000 tons, they have a crew of more than 5000 men and women. Each ship can carry approximately 80 aircraft.

The biggest battleships were the Imperial Japanese Navy’s Musashi and Yamato, 72,000 tons displacement, with armour over 16-inches thick and armed with nine 18.1-inch guns. Musashi was sunk in 1944 and Yamato in 1945 by American aircraft.

The World War Two British battleship HMS King George V was 42,000 tons.
