Battle of the Coral Sea order of battle

The Battle of the Coral Sea, a major engagement of the Pacific Theatre of World War II, was fought 4–8 May 1942 in the waters east of New Guinea and south of the Bismarck Islands between elements of the Imperial Japanese Navy and Allied naval and air forces from the United States (U.S.) and Australia.

To extend their empire in the Pacific to the conquest of Australia, the Japanese first had to capture the naval and air center of Port Moresby on the southeast coast of New Guinea. In order to extend the reach of their air searches for Allied naval forces, they resolved to simultaneously establish a seaplane base at Tulagi in the lower Solomon Islands. The U.S. learned of the Japanese plan, known as Operation Mo, through signals intelligence and sent two United States Navy carrier task forces and a joint Australian-American cruiser force to oppose the Japanese offensive.

The result was a strategic defeat for the Japanese, since their principal goal of landing troops at Port Moresby was thwarted, but a tactical defeat for the Allies, who suffered more significant ship losses.

Because the Japanese assumed the tactical initiative, their forces are listed first.
