Retributar,

I had done some research on the Franklin earlier this year and found the following. These are the citations for the two Medals of Honor awarded to crewmen on the USS Franklin. The ship's story stands out in many ways. It survived. The number and extent of casualties. The unrelenting toil involved in saving the ship.

thetwo!...yes!...i agree with you!...it's just amazing that that 'Aircraft-Carrier' was able to make it back to the repair dock's!.

Now!...in case some missed it!,...i was trying to get this information to everyone's attention!.

The Sen Toku I-400-class (伊四〇〇型潜水艦) submarines of the Imperial Japanese Navy were the largest submarines of World War II, and the largest ever built prior to the development of nuclear ballistic missile submarines in the 1960s. These were submarine aircraft carriers and each of them was able to carry 3 Aichi M6A Seiran aircraft underwater to their destinations. They were designed to surface, launch the planes then dive again quickly before they were discovered. They also carried torpedoes for close range combat.

The aircraft were the Aichi M6A1 Seiran, also carried by the Type AM submarines. Each of these monoplanes could carry one aerial torpedo or a bomb weighing up to 800kg. Powered by the 1,400hp Atsuta 32 engine (similar to Germany's DB601) they had a top speed of 295mph and were credited with a range of 642 nautical miles. The Sen Toku submarines carried four aerial torpedoes, three 800kg bombs, and twelve 250kg bombs to arm these aircraft. These aircraft had their assembly points coated with fluorescent paint to ease assembly in the dark, so four trained men could prepare an aircraft for launch in seven minutes. All three aircraft could be prepared, armed, and launched in 45 minutes.

On 26 July 1945, I-400 and I-401 set out on a combat mission to launch their aircraft in Kamikaze attacks on the American fleet anchorage at Ulithi. In coordination with a Kaiten attack, they were scheduled to launch early on 17 August, but by then hostilities had ceased. Both boats therefore returned to Japan and were surrendered to the Allies. After the war, these two were taken to the United States, examined, and finally scuttled in the Pacific in 1946. I-402 was converted to carry precious fuel to Japan from the East Indies, but never performed such a mission. She was scuttled off Goto Island in 1946. Construction of two further boats of this design, I-404 and I-405, was stopped before completion, although I-404 was 90% complete. A further 13 boats were canceled before construction started.

The I-400 class was designed to travel round-trip to anywhere in the world. A fleet of 18 boats was planned in 1942, and work started on the first in January 1943 at the Kure, Hiroshima arsenal. Within a year the plan was scaled back to five, of which only three (I-400 at Kure, and I-401 and I-402 at Sasebo) were completed.

[edit] Characteristics

Each submarine had four 3,000 horsepower (2.2 MW) engines and carried enough fuel to go around the world one-and-a-half times - more than enough to reach the United States traveling east or west. They displaced 6,500 tons and were over 400 feet (120 m) long, three times the size of the average contemporary submarine. They had a figure-eight hull shape affording additional strength to handle the on-deck hangar for housing the three aircraft. In addition, they had four anti-aircraft guns and a large deck gun along with eight torpedo tubes.

The Aichi M6A SeiranThey were able to carry three Aichi M6A Seiran aircraft, each carrying an 800 kilogram (1,764 lb) bomb 650 miles (1000 km) at 295 miles per hour (474 km/h). The existence of the Seiran was unknown to Allied intelligence. The wings of the Seiran folded back, the horizontal stabilizers folded down, and the top of the vertical stabilizer folded over so the overall forward profile of the aircraft was within the diameter of its propeller. When prepared for flight, they had a wing span of 40 feet (12 m) and a length of 38 feet (11.6 m). A crew of four could prepare and get all three airborne in 45 minutes. The planes were launched from a 120-foot (37-m) catapult on the deck of the giant submarine. A restored Seiran airplane is displayed at the National Air and Space Museum in Washington, D.C.. Only one was ever recovered and it had been ravaged by weather and souvenir collectors, but the restoration team was able to reconstruct it accurately.

[edit] Operational history

As the war turned against the Japanese and their fleet no longer had free rein in the Pacific, the Commander-in-Chief of the Japanese Combined Fleet, Admiral Isoroku Yamamoto, devised a daring plan to attack the cities of New York, Washington D.C., and other large American cities as well as to destroy the Panama Canal.

Officers of I-400 in front of the plane hangar, photographed by the US Navy following the capture of the submarine at sea, one week after the end of hostilities.One of Yamamoto’s plans was to use the sen toku (secret submarine attack), so that in the opening days of 1945, preparations were under way to attack the Panama Canal. The strategy was to cut the supply lines and access to the Pacific Ocean by U.S. ships. The plan was to sail westward through the Indian Ocean, around the southern tip of Africa, and attack the canal’s Gatun Locks from the east, a direction from which the Americans would not expect and were little prepared to defend. The flights would, of course, be one-way trips. None of the pilots expected to survive the attack, a tactic called tokko. Each pilot was presented with a tokko short sword, symbolic of the ultimate sacrifice.

Before the attack could commence from the Japanese naval base at Maizuru, word reached Japan that the Allies were preparing for an assault on the home islands. The mission was changed to attack the Allied naval base on Ulithi where the invasion was being assembled. Before that could take place, the Emperor announced the surrender of Japan.

On August 22, 1945, the crews of the submarines were ordered to destroy all their weapons. The torpedoes were fired without arming and the aircraft were launched without unfolding the wings and stabilizers. When I-401 surrendered to an American destroyer, the U.S. crew was astounded at its size. The commander of the submarine fleet, Captain Ariizumi, apparently decided on suicide rather than surrender to the Americans. He requested that his body be wrapped in the Japanese flag and buried at sea and shot himself. His body was never presented as proof of his death.

[edit] American inspections

Members of the US Navy inspecting the plane hangar of I 400.The U.S. Navy boarded and recovered 24 submarines including the three I-400 submarines, taking them to Sasebo Bay to study them. While there, they received a message that the Soviets were sending an inspection team to examine the submarines. To keep the technology out of the hands of the Soviets, Operation Road’s End was instituted. Most of the submarines were taken to a position designated as Point Deep Six, about 40 miles (60 km) west of Nagasaki and off the island of Gotō Islands, were packed with charges of C-2 explosive and destroyed. They are today at a depth of 200 meters.

US Navy personnel inspecting the gun of I-400.Four remaining submarines (I-400, I-401, I-201 and I-203 were sailed to Hawaii by U.S. Navy technicians for further inspection. Upon completion of the inspections, the submarines were scuttled in the waters off Kalaeloa near Oahu in Hawaii by torpedoes from the American submarine USS Cabezon on May 31, 1946. The reason for the scuttling is apparently that Soviet scientists were again demanding access to the submarines. The wreckage of I 401 was re-discovered by the Pisces deep-sea submarines of the Hawaii Undersea Research Laboratory in March 2005 at a depth of 820 meters. [1] [2] [3]

[edit] Post-War influences

It is sometimes suggested that the sen toku inspired the building of the large modern nuclear submarines and that the launching of aircraft from a submarine led to the idea of launching ballistic missiles.[citation needed] This has been disputed because the largest submarines ever, the Russian Typhoon-class, were built in ignorance of the sen toku. As early as the Second World War, US submarines had fired rockets from deck-mounted launchers against the Japanese mainland (the Japanese thought they were bombs from high-flying night bombers).

The hulls of modern nuclear submarines do not feature the figure-eight shape of the sen toku, but were based on the shape of the German Walther boats that were developed toward the end of the war. The Germans themselves based their design on the shape of dolphins.[citation needed] The Germans also experimented with rockets that were launched from U-boats and devised plans for using V-2 rockets against the United States.

This Sub was already in early production, i believe that at least 4 of these Sub's were already in service, undergoing sea trial's!.

[Nupremal]

it is a cool sub, but a total waste of resources and effort. Would not have had any appreciable effect.

[SeaMonkey]

Well maybe not Nupe, as far as the game mechanics, yes, but psychologically, think a moment.

"What if" an air attack on the West Coast USA happen to catch something significant, some 007 plan unveils perfectly, no reaction?

Imagine the repositioning of assets to prevent further escalations and then the unthinkable, another lucky attack.

Now you truly have some paranoia, the population demands action.

Remember the attack on Tokyo from "Shangri La", and the response, Midway and the Aleutians.

Do we need this parameter in the game?

[thetwo]

Not really. Far more damage was being done by the balloons being released that were travelling in the jet stream and igniting forest fires throughout the North American west. News reports were suppressed. Damage was substantial, but not econimically significant.

At best a few escort vessels and patrol aircraft would have been used off the NA coast. No real diversion of assets considering how much the US had to play with. The use of units preparing for deployment would have been easy without requiring the diversion of men and material from more critical requirements.

[scottsmm]

Thetwo when you say "damage was substantial" what do you mean by this, because truth is you rarely hear about. So I can't imagine losses where that great. On top of it all they did this act in the worst possible time (Spring). So there was little to no chance of the Japs achieving what they set out for.

I hope that these 'Behomouth-Beatuties' are included in this game!.

The Ships:

The largest warships of WW2 were the three Japanese Yamato class ships - the battleships Yamato and Musashi, and the Shinano (completed as an aircraft carrier A fourth ship was laid down but never completed). As designed, the Yamato and Musashi mounted nine 18" and twelve 6", later two 6" turrets were removed from Yamato in favour of a heavier anti-aircraft battery. Destined to never fight their rival American battlewagons, both Yamato and Musashi were lost to American airpower. Musashi was the victim of 20 torpedoes, 17 bombs and numerous near misses before succumbing on 24 October 1944. Yamato lasted until 7 April 1945 when she was sent on a one-way mission to bombard the American invasion fleet of Okinawa and then to beach herself and her crew were to join the troops ashore. This wasn't to be, instead Yamato was caught by American carrier aircraft and sunk along with the light cruiser Agano. When Yamato blew up, the blast was seen from over 200km away and the force of the blast destroyed many of the attacking aircraft.

http://www.steelnavy.com/images/GalleryImages/Musashi%20Bow.JPG

Battleship Musashi, sister of the 65,000-ton WW2 battleship Yamato, was built at Nagasaki, Japan. Commissioned in August 1942, she was stationed at Truk from January 1943 into 1944 as part of a heavy force covering the Central Pacific against the threat of an American offensive. When the latter materialized, with the invasion of the Marshalls and raids by aircraft carrier planes against Japanese positions further west, Musashi's base was moved to the Palaus. She was torpedoed by the submarine USS Tunny (SS-282) on 29 March 1944, necessitating repairs in Japan, during which her anti-aircraft firepower was enhanced.

In June 1944, with the torpedo damage repaired, Musashi took part in the Battle of the Philippine Sea. Her next, and last, major operation was the Battle of Leyte Gulf, in which the Japanese surface navy made a final major effort to repulse the U.S. drive into the Western Pacific. On 24 October 1944, while en route to the prospective battle area off the Leyte landing beaches, Musashi and her consorts were attacked by hundreds of U.S. Navy carrier aircraft. In this Battle of the Sibuyan Sea, she was hit by some nineteen torpedoes and seventeen bombs. Though her heavy protection withstood this massive damage to a degree probably unsurpassed by any other contemporary warship, Musashi capsized and sank about four hours after she received her last hit.

[John DiFool the 2nd]

Depends on whether there are two different BB classes in the game-one for the slower old-style battlewagons, and another for the fast kind (Iowas, Vittorio Venetos, Richilieus, Bismarck's, etc.), with further adjustments on a country-by-country basis.
