during which naval battle did the allies severely crippled japan’s navy
Battle of the Coral Sea Although a tactical victory for the Japanese in terms of ships sunk, the battle would prove to be a strategic victory for the Allies for several reasons. The battle marked the first time since the start of the war that a major Japanese advance had been checked by the Allies. More importantly, the Japanese fleet carriers Shōkaku and Zuikaku – the former damaged and the latter with a depleted aircraft complement – were unable to participate in the Battle of Midway the following month, while Yorktown did participate, ensuring a rough parity in aircraft between the two adversaries and contributing significantly to the U.S. victory in that battle. The severe losses in carriers at Midway prevented the Japanese from reattempting to invade Port Moresby from the ocean and helped prompt their ill-fated land offensive over the Kokoda trail. Two months later, the Allies took advantage of Japan's resulting strategic vulnerability in the South Pacific and launched the Guadalcanal Campaign; this, along with the New Guinea Campaign, eventually broke Japanese defenses in the South Pacific and was a significant contributing factor to Japan's ultimate surrender in World War II.
Battle of Leyte Gulf It was fought in waters near the Philippine islands of Leyte, Samar and Luzon, from 23â€“26 October 1944, between combined American and Australian forces and the Imperial Japanese Navy. On 20 October, United States troops invaded the island of Leyte as part of a strategy aimed at isolating Japan from the countries it had occupied in Southeast Asia, and in particular depriving Japanese forces and industry of vital oil supplies. The Imperial Japanese Navy (IJN) mobilized nearly all of its remaining major naval vessels in an attempt to defeat the Allied invasion but was repulsed by the U.S. Navy's Third and Seventh fleets. The IJN failed to achieve its objective, suffered heavy losses, and never sailed to battle in comparable force thereafter. The majority of its surviving heavy ships, deprived of fuel, remained in their bases for the rest of the Pacific War and suffered under heavy sustained aerial attack.[6][1]
