The BPF formally came into being on 22 November 1944 from the remaining ships of the former Eastern Fleet then being re-named the East Indies Fleet and continuing to be based in Trincomalee. The British Pacific Fleet's main base was at Sydney, Australia, with a forward base at Manus Island. One of the largest fleets ever assembled by the Royal Navy, by Victory over Japan Day it consisted of over two hundred ships and submarines and more than 750 aircraft; including four battleships and six fleet aircraft carriers, fifteen smaller aircraft carriers, eleven cruisers and numerous smaller warships, submarines, and support vessels.

Operation Wigwam involved a single test of the Mark 90 "Betty" nuclear bomb. It was conducted between Operation Teapot and Project 56 on May 14, 1955, about 500 miles (800 km) southwest of San Diego, California. 6,800 personnel aboard 30 ships were involved in Wigwam. The purpose of Wigwam was to determine the vulnerability of submarines to deeply detonated nuclear weapons, and to evaluate the feasibility of using such weapons in a combat situation. The task force commander, Admiral John Sylvester, was embarked on the task force flagship USS Mount McKinley. WIGWAM was the first atomic test in the deep ocean, and it remains the only test that has been conducted in water deeper than 1,000 ft (300 m).

The Pacific Squadron was part of the United States Navy squadron stationed in the Pacific Ocean in the 19th and early 20th centuries. Initially with no United States ports in the Pacific, they operated out of storeships which provided naval supplies and purchased food and obtained water from local ports of call in the Hawaiian Islands and towns on the Pacific Coast. Throughout the history of the Pacific Squadron, American ships fought against several enemies. Over one-half of the United States Navy would be sent to join the Pacific Squadron during the Mexican–American War. During the American Civil War, the squadron was reduced in size when its vessels were reassigned to Atlantic duty. When the Civil War was over, the squadron was reinforced again until being disbanded just after the turn of the 20th century.

The Singapore strategy was a naval defence policy of the British Empire that evolved in a series of war plans from 1919 to 1941. It aimed to deter aggression by the Empire of Japan by providing for a base for a fleet of the Royal Navy in the Far East, able to intercept and defeat a Japanese force heading south towards India or Australia. To be effective it required a well-equipped base; Singapore, at the eastern end of the Strait of Malacca, was chosen in 1919 as the location of this base; work continued on this naval base and its defences over the next two decades.

The Pacific War, sometimes called the Asia–Pacific War, was the theater of World War II that was fought in Asia, the Pacific Ocean, the Indian Ocean, and Oceania. It was geographically the largest theater of the war, including the vast Pacific Ocean theater, the South West Pacific theater, the South-East Asian theater, the Second Sino-Japanese War, and the Soviet–Japanese War.

The Pacific Ocean theater, during World War II, was a major theater of the war between the Allies and the Empire of Japan. It was defined by the Allied powers' Pacific Ocean Area command, which included most of the Pacific Ocean and its islands, while mainland Asia was excluded, as were the Philippines, the Dutch East Indies, Borneo, Australia, most of the Territory of New Guinea, and the western part of the Solomon Islands.
