Operation Sea Shark Invasion of the Four Southern Marianas Islands Order of Battle Revised As of June 13, 1943 Opening Comments Since the inception of the war, the Allies have planned to invade Saipan, Tinian, Rota, and Guam (the four southern Marianas Islands) during the month of June, 1943. Operation Sea Shark is an integral part of the Allied Grand Strategy to implement a Naval Blockade of Japan Proper and to transport ground forces, aircraft, and supply to China in support of Operation Land Shark (the land war to conquer Burma, China, Manchukua, and Korea). Consolidated Data Excluding the Submarines, Minesweepers, and PT boats under the Command of Captain Haggard, the Invasion Fleet is comprised of the following: • 3,120 Miles from Pearl to Objectives • 427 Wildcat Fighters • 271 Hellcat Fighters • 134 Dauntless Dive Bombers • 46 Task Forces • 971 Ships • 20 Carriers • 23 Battleships • 25 CAs • 26 CLs • 7 CLAAs • 95 Destroyers • 22 AOs • 262,310 Fuel Replenishment • 1,943 Saipan Assault Value • 788 Tinian Assault Value • 703 Rota Assault Value • 3,131 Guam Assault Value • 337,339 Saipan Supply • 331,106 Tinian Supply • 330,480 Rota Supply • 622,657 Guam Supply • 1,621,582 Total Supply • 14,000,000 Rolls of Toilet Paper Task Forces I have no doubt, that many of The War College members could have done a much better job creating the Invasion Fleet Task Forces.
