British Pacific Fleet - Active Service

Active Service

Major actions in which the fleet was involved included Operation Meridian, air strikes in January 1945 against oil production at Palembang, Sumatra. These raids, conducted in bad weather, succeeded in reducing the oil supply of the Japanese Navy. A total of 48 FAA aircraft were lost due to enemy action and crash landings; they claimed 30 Japanese planes destroyed in dogfights and 38 on the ground.

The United States Navy (USN), which had control of Allied operations in the Pacific Ocean Areas, gave the BPF combat units the designation of Task Force 57 (TF-57) when it joined Admiral Raymond Spruance's United States Fifth Fleet on 15 March 1945. On 27 May 1945, it became Task Force 37 (TF-37) when it became part of Admiral William Halsey's United States Third Fleet.

In March 1945, while supporting the invasion of Okinawa, the BPF had sole responsibility for operations in the Sakishima Islands. Its role was to suppress Japanese air activity, using gunfire and air attack, at potential Kamikaze staging airfields that would otherwise be a threat to U.S. Navy vessels operating at Okinawa. The carriers were subject to heavy and repeated kamikaze attacks, but because of their armoured flight decks, the British aircraft carriers proved highly resistant, and returned to action relatively quickly. The USN liaison officer on the Indefatigable commented: "When a kamikaze hits a U.S. carrier it means 6 months of repair at Pearl . When a kamikaze hits a Limey carrier it’s just a case of 'Sweepers, man your brooms.'”

Fleet Air Arm Supermarine Seafires saw service in the Pacific campaigns. Due to their good high altitude performance and lack of ordnance-carrying capabilities (compared to the Hellcats and Corsairs of the Fleet) the Seafires were allocated the vital defensive duties of Combat Air Patrol (CAP) over the fleet. Seafires were thus heavily involved in countering the Kamikaze attacks during the Iwo Jima landings and beyond. The Seafires' best day was 15 August 1945, shooting down eight attacking aircraft for a single loss.

In April 1945, the British 4th Submarine Flotilla was transferred to the major Allied submarine base at Fremantle, Western Australia, as part of BPF. Its most notable success in this period was the sinking of the heavy cruiser Ashigara, on 8 June 1945 in Banka Strait, off Sumatra, by HMS Trenchant and HMS Stygian. On 31 July 1945, in Operation Struggle, the British midget submarine XE3, crewed by Lieutenant Ian Fraser, Acting Leading Seaman James Magennis, Sub-Lieutenant William James Lanyon Smith, RNZNVR, and Engine Room Artificer Third Class, Charles Alfred Reed, attacked Japanese shipping at Singapore. They sank the heavy cruiser Takao, which settled to the bottom at its berth. Fraser and Magennis were both awarded the Victoria Cross, Smith received the Distinguished Service Order (DSO) and Reed the Conspicuous Gallantry Medal (CGM).

Battleships and aircraft from the fleet also attacked the Japanese home islands. The battleship King George V bombarded naval installations at Hamamatsu, near Tokyo; the last time a British battleship fired in action. Meanwhile, carrier strikes were carried out against land and harbour targets including, notably, the disabling of a Japanese escort carrier by British naval aircraft. Although, during the assaults on Japan, the British commanders had accepted that the BPF should become a component element of the U.S. 3rd Fleet, the U.S. fleet commander, William Halsey, excluded British forces from a raid on Kure naval base on political grounds. Halsey later wrote, in his memoirs: "it was imperative that we forestall a possible postwar claim by Britain that she had delivered even a part of the final blow that demolished the Japanese fleet.... an exclusively American attack was therefore in American interests."

The BPF would have played a major part in a proposed invasion of the Japanese home islands, known as Operation Downfall, which was cancelled after Japan surrendered. The last naval air action in World War II was on VJ-Day when British carrier aircraft shot down Japanese Zero fighters.

Lt Robert Hampton Gray, a Canadian naval airman who piloted a Vought Corsair with 1841 Naval Air Squadron on HMS Formidable, was awarded the Victoria Cross, following his death in an attack on a Japanese destroyer at Onagawa Wan, Japan, on August 9, 1945.

Fighter squadrons from the fleet claimed a total of 112.5 Japanese aircraft shot down. 1844 Squadron NAS (flying Hellcats) was the top-scoring squadron, with 28 claims.
