After being completed in late 1940, she was briefly assigned to the Home Fleet before being transferred to the Mediterranean Fleet as a replacement for her crippled sister ship Illustrious.

She was laid down in January 1914 and launched in April 1915; she was completed in May 1916, but was not ready for service in time to participate in the Battle of Jutland at the end of the month. She served with the Grand Fleet for the remainder of the First World War, but did not see action. In the early 1930s, she was assigned to the Mediterranean Fleet and based in Malta.
HMS Warspite was one of five Queen Elizabeth-class battleships built for the Royal Navy during the early 1910s. Completed during the First World War in 1915, she was assigned to the Grand Fleet and participated in the Battle of Jutland.

The ship was named after the Tone River, in the Kantō region of Japan and was completed on 20 November 1938 at Mitsubishi's Nagasaki shipyards. Tone was designed for long-range scouting missions and had a large seaplane capacity. She was extensively employed during World War II usually providing scouting services to their aircraft carrier task forces. She almost always operated in this capacity in conjunction with her sister ship Chikuma.
The Indian Ocean raid, also known as Operation C or Battle of Ceylon in Japanese, was a naval sortie carried out by the Imperial Japanese Navy (IJN) from 31 March to 10 April 1942. Japanese aircraft carriers under Admiral Chūichi Nagumo struck Allied shipping and naval bases around British Ceylon, but failed to locate and destroy the bulk of the British Eastern Fleet. The Eastern Fleet, commanded by Admiral Sir James Somerville, was forewarned by intelligence and sailed from its bases prior to the raid; its attempt to attack the Japanese was frustrated by poor tactical intelligence.
Admiral of the Fleet Sir James Fownes Somerville, was a Royal Navy officer. He served in the First World War as fleet wireless officer for the Mediterranean Fleet where he was involved in providing naval support for the Gallipoli Campaign. He also served in the Second World War as commander of the newly formed Force H: after the French armistice with Germany, Winston Churchill gave Somerville and Force H the task of neutralizing the main element of the French battle fleet, then at Mers El Kébir in Algeria. After he had destroyed the French Battle fleet, Somerville played an important role in the pursuit and sinking of the German battleship Bismarck.
The Battle of Madagascar was a Allied campaign to capture the Vichy French-controlled island Madagascar during World War II. The seizure of the island by the British was to deny Madagascar's ports to the Imperial Japanese Navy and to prevent the loss or impairment of the Allied shipping routes to India, Australia and Southeast Asia. It began with Operation Ironclad, the seizure of the port of Diego-Suarez near the northern tip of the island, on 5 May 1942.
Operation Cockpit was an Allied attack against the Japanese-held island of Sabang on 19 April 1944. It was conducted by aircraft flying from British and American aircraft carriers and targeted Japanese shipping and airfields. A small number of Japanese ships and aircraft were destroyed, and one American aircraft was lost. While the attack was successful tactically, it failed to divert Japanese forces from other areas as had been hoped.

The invasion of Tulagi, on 3–4 May 1942, was part of Operation Mo, the Empire of Japan's strategy in the South Pacific and South West Pacific Area in 1942. The plan called for Imperial Japanese Navy troops to capture Tulagi and nearby islands in the British Solomon Islands Protectorate. The occupation of Tulagi by the Japanese was intended to cover the flank of and provide reconnaissance support for Japanese forces that were advancing on Port Moresby in New Guinea, provide greater defensive depth for the major Japanese base at Rabaul, and serve as a base for Japanese forces to threaten and interdict the supply and communication routes between the United States and Australia and New Zealand.
