Scientists have solved the longstanding mystery of a Japanese submarine missing since 1946 after stumbling across it in the Pacific Ocean off the coast of Hawaii.
The Sen-Toku I-400 submarine – one of the largest pre-nuclear underwater vessels ever built – was discovered lying 2,300 feet beneath the surface of the ocean off the southwest coast of Oahu.
The whereabouts of the 400-foot long mega-vessel has been the subject of widespread academic debate since its disappearance in 1946 when it was preparing to attack the Panama Canal before being scuttled by US forces.
A Jappo sub attempting to attack something in 1946? A year after surrender?
Err, no, not really.
The wreckage was identified by its distinct aircraft launch ramp, deck crane and stern running lights, with its aircraft hanger broken off, the likely result of the three US Navy torpedo blasts that sunk it in 1946.
So, there was indeed a plan for that sub and a few others to attack the Panama Canal. But that was in 1945. At the end of the war the sub and crew surrendered and was taken to Hawaii. Where, in 1946, the Americans scuttled it with those torpedoes in order to stop the Soviets getting a good look at it.
People need to be seriously ignorant of history if they think that the Japanese Navy was sending subs across the Pacific in 1946.
