Submarine I-400

Of plastic parts assembled Japanese WWII submarine I-400. Created as part of a plan to attack major cities in the United States and the Panama Canal, the three I-400 class large aircraft carrier submarines were quite technologically advanced. Featuring an extremely long range and heavily armed with both torpedoes and deck guns, they were also equipped with catapults to launch their three Aichi M6A Seiran aircraft. While on their way to attack the Panama Canal, the submarines were ordered to attack the Allied naval base at Ulithi instead. However, hostilities ended before any attack could be launched. After surrendering to U.S. forces, the I-400 was eventually sailed to Hawaii, where they were studied and then scuttled.
