What is Japan's "pocket" submarine?

In World War II, when the Japanese navy attacked American warships moored at Pearl Harbor, it not only dispatched aircraft carrier formations, but also dispatched pocket submarines.

In the whole task force that attacked Pearl Harbor, there was a humble submarine formation, which was the sixth fleet in the task force formation. The Sixth Fleet consists of three submarine squadrons. These submarines are "Iraq" class submarines, which can travel to and from Japan and the United States without replenishment. Most of these submarines are equipped with 20 "spear" torpedoes, while others are equipped with extremely secret weapons-pocket submarines.

These extremely secret pocket submarines have a displacement of less than 50 tons, and the battery-driven motor is used as the propulsion power of the submarine. If you sail at 4 nautical miles per hour, you can sail for 25 hours. At the same time, this submarine can sail at a high speed of 24 nautical miles per hour in a short time. Each submarine is equipped with two crew members, one is responsible for driving and commanding, and the other is mainly responsible for route observation. Each pocket submarine has two 18 inch torpedoes. When participating in the war, the pocket submarine was thrown into the sea from the submarine carrier (because of its limited endurance, it was brought to the vicinity of the battle site), and then sneaked into the enemy ship group to blow up the enemy ship under the impetus of its own power plant, and then sneaked back to the submarine carrier after completing the task.

194 1 In the summer of, Captain Azithromycin, commander of Japanese pocket submarines, proposed to the General Staff of the Imperial Tokyo that if the commander of the fleet allowed him to drive the pocket submarines into Pearl Harbor, the anchorage of American ships, he could destroy the huge American fleet in Pearl Harbor with six pocket submarines. At this time, the commander of the General Staff, Chai Yuan, had already arranged the plan of air attack on Pearl Harbor. Commander Chai Yuan thought: "If the pocket submarine is found an unprecedented hour or two before the attack fleet arrives at Pearl Harbor, then all kinds of bomb threats on the Japanese attack plane will be lost. It is much more likely to raid Pearl Harbor with aviation than with a pocket submarine."

The real commander Harada's point of view is not that Jeannot Buazithromycin gave up the pocket submarine to participate in the Pearl Harbor naval battle. With the joint efforts of the crew of the pocket submarine headed by Nobuo Aki, Isoroku Yamamoto, commander of the joint fleet of the Japanese navy, finally agreed that the pocket submarine would participate in the attack on Pearl Harbor. Of course, Isoroku Yamamoto also made the following regulations for the crew of the pocket submarine: "The pocket submarine shall not rush into the channel of Pearl Harbor, and all actions of the pocket submarine shall not endanger the sudden attack of the aircraft carrier."

1942 65438+On February 6th, in the sea off Pearl Harbor 10 nautical mile, five "Yi" submarines with pocket submarines were quietly lurking. After the carrier aircraft on the Japanese aircraft carrier dropped bombs over Pearl Harbor, they entered the port for robbery. At 3 am on the 7th, all five "Iraq" submarines surfaced, and the pilots and assistants on the pocket submarines were waiting to enter their own boats. After a brief departure ceremony, the pocket submarines began their own voyage.

At 7: 50 a.m. on the 7th, the aircraft on the aircraft carrier launched a fierce attack on the American fleet in Pearl Harbor, and all the pocket submarines skillfully crossed the American anti-submarine network. Straight to the battleship still floating on the sea of Pearl Harbor.

When the carrier-based aircraft and other warships on the aircraft carrier attacked the American ship, the pocket submarine also began to fight. However, because the technical performance of the pocket submarine is far from the actual requirements, despite efforts, the pocket submarine still failed to achieve any success, or was sunk or disappeared, and finally all of them were buried in the surging sea near Pearl Harbor.
