The current political climate is tense due to escalating tensions worldwide. Ongoing conflicts include those between Israel and Hamas, Russia and Ukraine, and the Houthi rebels and the United States who are fighting in the Red Sea. There is also increasing competition between China and the U.S. Many nations, including China, are strengthening their naval capabilities, while the U.S. Navy is continually modernizing its fleet to maintain readiness.

Navies have historically played significant roles in warfare and will no doubt continue to do so. World War II saw some major naval battles, marking a turning point in naval warfare with the advent of carrier-based combat. Global powers vied for dominance across oceans, using statae-of-the-art technology of the time. The United States played a prominent role in many of these battles, particularly in the Pacific Theater. 

24/7 Wall St. analyzed various historical accounts of naval battles during the war to identify the largest American naval battles of WWII. Naval battles were ranked based on how many warships were involved in each battle. Supplemental information on when and where these battles took place, notable ships involved, the size and battle order of each armada, and how many ships were sunk in each battle came from various sources.

Two significant clashes in the Pacific Theater were the Battle of Midway and the Battle of Leyte Gulf. Taking place from June 4 to 7, 1942, the Battle of Midway was a critical moment in the war. With 130 warships engaged, the battle took place six months after the Pearl Harbor attack, as the United States sought to retaliate against its losses and shift the momentum of the conflict in its favor.

Japan’s Imperial Navy deployed a large carrier force, while the U.S. Navy deployed its entire fleet of heavy aircraft carriers, putting a new emphasis on air power in naval battles. Numerous supporting warships and submarines were engaged as well. During the conflict, the United States successfully surprised the Japanese fleet, sinking four heavy aircraft carriers and destroying over 300 aircraft. Although the U.S. lost one aircraft carrier and nearly 150 aircraft, this victory marked a crucial turning point in the Pacific Theater, shifting the balance of power decisively in favor of the U.S.

The Battle of Leyte Gulf took place between October 23 and 26, 1944, and is recognized as not just the largest naval battle of WWII but also in all of history. As the U.S. sought to regain control of the Phillipines with the Japanese hoping to stop their advance, this clash involving 279 warships proved critical in the war’s final stages. This battle also became infamous because the Japanese unveiled a new tactic of suicide air attacks, known as kamikaze.

Despite the devastation caused by these attacks, the United States prevailed, destroying the four remaining Japanese aircraft carriers and crippling Japan’s naval capabilities. These battles definitively shifted the balance of power in favor of the U.S., ultimately leading to Japan’s surrender.
