For the April 1945 invasion of Okinawa (Allied codename: Operation Iceberg), the Allies assembled the most powerful naval force in history. Since the few remaining capital ships of the Imperial Japanese Combined Fleet had been sunk or otherwise put out of action at the Battle of Leyte Gulf, the Allies were effectively unopposed in terms of major surface vessels; a single mission consisting of the superbattleship Yamato and a few escorts was undertaken, but the task force did not get within 200 nautical miles (370 km; 230 mi) of the invasion area. The main Japanese naval opposition within the invasion area came from hundreds of Imperial Japanese Navy Shin'yō-class suicide motorboats and Maru-Ni Imperial Japanese Army attack boats.
Since the Japanese air arm had been equally decimated by this point in the war, the lack of trained and experienced pilots led them to deploy the kamikaze extensively in the waters off Okinawa.

Royal Navy combat ships:
5 fleet carriers, 2 battleships, 7 light cruisers, 14 destroyers
Losses
The smaller ships were least able to withstand damage from kamikaze attacks.
The roles of Commander in Chief, Pacific Ocean Areas (CINCPOA) and Commander in Chief, U.S. Pacific Fleet (CINCPAC) were both exercised by Admiral Chester W. Nimitz from his headquarters at Pearl Harbor, Hawaii.
Since the "Big Blue Fleet" was at this time under the command of Admiral Raymond Spruance aboard his flagship USS Indianapolis, the force was designated Fifth Fleet. (It had been Third Fleet until Spruance relieved Admiral William Halsey in January, as part of the "alternating command" system).
The ships and troops of Operation Iceberg were under direct operational command of Rear Admiral Richmond Kelly Turner aboard amphibious command ship Eldorado.
Son of a Confederate army general, Lt. Gen. Simon Bolivar Buckner, Jr. was one of four US lieutenant generals to die during World War II, but the only one to die by enemy action. On 18 June, Buckner was visiting a forward observation post when a Japanese artillery shell struck a coral outcropping, fragments of which struck Buckner in the chest. Command of Tenth Army passed to Marine Maj. Gen. Roy S. Geiger.

The following table lists the Allied naval vessels that received damage or were sunk in the Battle of Okinawa between 19 March – 30 July 1945. The table lists a total of 147 damaged ships, five of which were damaged by enemy suicide boats, and another five by mines. One source estimated that total Japanese sorties during the entire Okinawa campaign exceeded 3,700, with a large percentage kamikaze, and that the attackers damaged slightly more than 200 Allied vessels, with 4900 naval officers and seamen killed and roughly 4,824 wounded or missing. [6] [7] The USS Thorton is not listed as it was damaged as the result of a collision with another US ship. Those ships in a pink background, and with an asterisk were sunk or had to be scuttled due to irreparable damage. Of those sunk, the majority were relatively smaller ships; these included destroyers of around 300–450 feet. A few small cargo ships were also sunk, several containing munitions which caught fire. Those ships whose names are preceded by a "#" pound sign were scrapped or decommissioned as a result of damage.
The Battle of Leyte Gulf was the largest naval battle of World War II and by some criteria the largest naval battle in history, with over 200,000 naval personnel involved. It was fought in waters near the Philippine islands of Leyte, Samar, and Luzon from 23 to 26 October 1944 between combined American and Australian forces and the Imperial Japanese Navy (IJN), as part of the invasion of Leyte, which aimed to isolate Japan from the colonies that it had occupied in Southeast Asia, a vital source of industrial and oil supplies.
USS Saratoga (CV-3) was a Lexington-class aircraft carrier built for the United States Navy during the 1920s. Originally designed as a battlecruiser, she was converted into one of the Navy's first aircraft carriers during construction to comply with the Washington Naval Treaty of 1922. The ship entered service in 1928 and was assigned to the Pacific Fleet for her entire career. Saratoga and her sister ship, Lexington, were used to develop and refine carrier tactics in a series of annual exercises before World War II. On more than one occasion these exercises included successful surprise attacks on Pearl Harbor, Hawaii. She was one of three prewar US fleet aircraft carriers, along with Enterprise and Ranger, to serve throughout World War II.
USS Kasaan Bay (CVE-69) was the fifteenth of fifty Casablanca-class escort carriers built for the United States Navy during World War II. She was named after Kasaan Bay, a name assigned to the bay by the local Haida Indians. The bay is located within Prince of Wales Island, which at the time was a part of the Territory of Alaska. The ship was launched in October 1943, commissioned in December, and served as a transport carrier in both the Atlantic and the Pacific, as well as taking part in Operation Dragoon, the Allied invasion of occupied Southern France. Her aircraft provided air support and strategic bombing capabilities, disrupting German supply lines, and earning Kasaan Bay a battle star. Postwar, she participated in Operation Magic Carpet. Ultimately, she was broken up in March 1960.
USS Petrof Bay (CVE-80) was the twenty-sixth of fifty Casablanca-class escort carriers built for the United States Navy during World War II. She was named after Petrof Bay, which in turn was named in 1928 after Ivan Petroff, a Russian Alaskan who served as a special census agent for the 1880 United States census. The bay is located within Kuiu Island, which at the time was a part of the Territory of Alaska. The ship was launched in January 1944, commissioned in February, and served in support of the Mariana and Palau Islands campaign, the Philippines campaign, including the Battle off Samar, the Battle of Iwo Jima, and the Battle of Okinawa. She was decommissioned in July 1946, when she was mothballed in the Atlantic Reserve Fleet. Postwar, she participated in Operation Magic Carpet. Ultimately, she was broken up in September 1959.
This is the order of battle for the Battle of Midway, a major engagement of the Pacific Theatre of World War II, fought 4–7 June 1942 by naval and air forces of Imperial Japan and the United States in the waters around Midway Atoll in the far northwestern Hawaiian Islands.
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.
Kinu (鬼怒) was the fifth of the six ships completed Nagara-class light cruiser in the Imperial Japanese Navy, named after the Kinu River in Tochigi prefecture Japan. She was active in World War II in various campaigns in Malaya, the Dutch East Indies and New Guinea before being sunk by United States Navy carrier-based aircraft in the Philippines in 1944.
This is the complete order of battle of Allied and Japanese forces during the Borneo campaign of 1945. As the campaign was fought in three geographically separate areas and the same air and naval units supported more than one of these battles the order of battle is split into the three areas.
As it turned out these operations were different from those that had gone before. The minefields were heavier and, for the first time in any Pacific campaign, man-made obstacles had been laid off the beaches.
This is the order of battle of the Japanese and Russian fleets at the Battle of Tsushima on 27–28 May 1905.
On 15 August 1944, Allied forces carried out Operation Dragoon, a set of simultaneous amphibious landings by three US infantry divisions followed by four Free French divisions along the Mediterranean coast of France. The main landings were preceded by nighttime paratroop drops and commando beach landings. This was a phase of the European Theatre of World War II.
Operation Tungsten was a Second World War air raid conducted by the Royal Navy that targeted the German battleship Tirpitz at her base in Kaafjord in the far north of Norway on 3 April 1944.
On 20 November 1943, simultaneous landings were made by United States Marine Corps forces on Tarawa and United States Army forces on Makin, two coral atolls located in the Gilbert Islands chain in the South-Central Pacific.
The Battle of Leyte Gulf, generally considered to be the largest naval combat in history, was fought 24–25 October 1944 in the waters of the Philippine Islands by elements of the Imperial Japanese Navy's Combined Fleet and the United States Navy's Pacific Fleet. Of the five separate engagements that made up the battle as a whole, the forces involved in the three principal ones are listed here.
The Battle of the Philippine Sea was fought 19–20 June 1944 in the waters west of the Mariana Islands by elements of the Imperial Japanese Navy's Combined Fleet and of the United States Navy's Pacific Fleet. The battle resulted from the Japanese reaction to the American invasion of the island of Saipan. Instead of attacking the troop transports off Saipan, Admiral Toyoda chose to engage the American carrier forces in what he intended to be the long-awaited “decisive battle” that would crush U.S. naval power.
On 7 August 1942, US and Australian naval forces undertook the invasion of the Japanese-held islands of Guadalcanal and Tulagi in the lower Solomon Islands chain, the first Allied offensive in the Pacific Theatre. The landing of the US 1st Marine Division on the beaches of Savo Sound began the unexpectedly long and extremely arduous Guadalcanal Campaign, lasting officially until 9 February 1943.
The Battle of the Eastern Solomons was fought August 23–25, 1942 in the waters east and northeast of the Solomon Islands by forces of the Imperial Japanese Navy's Combined Fleet and the US Navy's Pacific Fleet. The battle resulted from a major effort by the Japanese to reinforce their troop strength on the island of Guadalcanal. The Japanese high command had realized this reinforcement was necessary following the annihilation of the Ichiki Detachment by the 1st Marines a few days earlier.
Operation Avalanche was the codename for the combined US and British landings on the southwest coast of Italy on 9 September 1943 as part of the Allied effort in the Mediterranean Theater during World War II. The forces landed consisted of the US Fifth Army under Lieutenant General Mark W. Clark. The Fifth Army was made up of the British X Corps, which landed south of the town of Salerno, and the US VI Corps, which landed at the town of Paestum.
The Battle of the Santa Cruz Islands was fought 25–27 October 1942 in the waters northwest of the Santa Cruz Islands by forces of the Imperial Japanese Navy's (IJN) Combined Fleet and the United States Navy's (USN) Pacific Fleet. The battle resulted from a major Japanese offensive with the goal to drive the US forces from Guadalcanal.
On 17 October 1944, troops of the United States Sixth Army under the direct command of Lieutenant General Walter Krueger, invaded the Philippine island of Leyte. This operation was the beginning of General Douglas MacArthur's fulfillment of his promise in March 1942 to the Filipino people that he would liberate them from Japanese rule.
On 15 June 1944, United States Marine and Army forces landed on the southwest coast of the island of Saipan in the central Marianas chain. US forces declared Saipan secure on 9 July.
