Japan Mini Submarine - Here's what you need to remember: One hour before the air raid. A small group of Japanese submarines attempted to slip within the defenses of Pearl Harbor.
On December 7, 1941, an Imperial Japanese Navy aircraft landed in Hawaii. The US naval base at Pearl Harbor was destroyed. But it was not the first shots fired by Japanese warplanes that brought the United States into the great war in the Pacific.

An hour before the air raid. A small force of Japanese submarines entered the harbor defenses like thieves in the night, trying to break through the Battleship line. Unlike air raids, the Crew failed spectacularly — the story was mostly forgotten.

In the 1930s, Japan and the United States were on a collision course. Tokyo's decision to invade China in 1931, and their six-year escalation of brutality, created tensions that were ultimately irreversible.
The United States responded to China by increasing sanctions, including an oil embargo in July 1941 that affected the Japanese economy. Japan's military leaders wanted to capture the Dutch East Indies to gain access to its oil wealth, but they knew that war with the United States would follow.
When negotiations between the United States and Japan came within striking distance of a peace agreement, Roosevelt was a difficult negotiator, and Japanese leaders demanded a complete withdrawal from China. They refused.
Therefore, the Japanese Admiral Yamamoto began planning a "short war of victory". The key to this plan was to withdraw the US Pacific Fleet from Pearl Harbor in Hawaii to buy time for Japanese forces to occupy the Western Pacific.
Japanese Submarines Of The Second World War
The Navy coordinated an underwater attack using submarines as the main attack, along with a major air attack by the Japanese Navy.
During the Second World War, Japan, Great Britain, Italy and Germany secretly penetrated into shallow water; Midget submarines were used to attack harbors defended by weak capital ships. The Japanese Navy's medium submarines hid their development by calling them Type A Kō-hyōteki, or "Target A".
Japanese officials hope the 78-foot-long submarines will fool foreign observers into thinking the submarines are mock vessels for naval exercises. In fact, each 46-ton submarine had two crew members and installed two 800-pound 450 mm Type 97 torpedoes.
Small submarines can dive at a speed of 26 miles per hour, but cannot dive deeper than 100 meters. Most importantly, the Type As has no engine and runs only on batteries.

This gave the smallest ship a maximum endurance of 12 hours at 6 miles per hour. Submarines tend to run out of power in real combat.
As a result, large numbers of submarines were forced to bring the Type As closer to the target area. Still, due to battery limitations, the small central device will not be able to make it back to safety. Each 300-pound scuttling charge is a self-destruct device.
It's hard enough to get promoted. Small boats are difficult to control even when sailing in a straight line, so sailors have to move the lead weight back and forth to stabilize the boat.
Despite these obvious problems, on October 19, 1941, the Japanese Navy began retrofitting five Type A subclasses with improved pneumatic operating equipment as well as net cutters and guards to protect against anti-submarine nets. Workers at the Kure Naval District paint submarine lights to hide them from enemy observers.

The midshipmen then went to the Kamegakubi Naval Proving Ground, where the crews of five Type C-1 submarines; I-16; I-18; I-20; They loaded up behind I-22 and I-24. On November 25, 1941, the mothers sailed to Pearl Harbor.
Follow up time; A special combat unit called "Mountain Climb Niitaka 1208". This means that the authorities in Tokyo have indicated that they will not seek a diplomatic solution and proceed with the attack on Pearl Harbor.
On December 6, 1941, C-1s swam to within 12 miles of Pearl Harbor. Then between midnight and 3:30 p.m. The next day the ships released their bad cargo.
For the crew, getting into Pearl Harbor was a big challenge. Ships can enter the harbor only through a 65-foot deep channel protected by a 35-foot deep anti-submarine tube.

The boats on each side of the net are pushed aside to allow friendly boats to pass. In addition, American destroyers maneuvered in a five-mile radius around the harbor entrance, supporting PBY Catalina maritime patrol aircraft with observation eyes in orbit.
On paper the Japanese aimed a well-planned heist attack on the submarine. Midget auxiliaries could hide behind American ships passing through space in the anti-submarine net.
American warships escaping from the explosion would then drop their torpedoes from the air, causing chaos in the harbor and lowering them under water. After that, the Central Guard will not share the Hawaiian island of Lanai.
Submarines I-68 and I-69 had to wait no more than 24 hours to pick up the surviving crew. The Japanese have no plans to bring back their own Type Kama.

If all had gone well, American officials would have received Japan's declaration of hostility shortly before the attack began. However, things did not go according to plan.
Shortly before 4:00 am, the minesweeper USS Condor sighted the location of the Ha-20 submarine and ordered the destroyer USS Ward to cross and search the area.
More than an hour and a half later, crews on the Ward found the Periscope as it passed through the anti-submarine net behind the cargo ship Antares. Ward charged the van when a PBY Catalina patrol plane dropped smoke marks near the base.
The fighters fired two shots at the ship's 4-inch main gun at less than 100 meters, followed by four depth charges. Type A was lost in the water.

More than an hour and a half later, the crew on Ward saw the periscope as the cargo ship Antares passed through the anti-submarine net. Ward charged the van when a PBY Catalina patrol plane dropped smoke marks near the base.
When the batteries absorb seawater, they release dangerous chlorine gas. Heavy gunfire eventually destroyed the periscope and disabled the midget submarine's indestructible torpedo.
Sakamaki decided to try to return their big ship to the mothers. He and Inagaki pass out as their ship fills with inhalant gas.
The two regained consciousness in the evening and decided to land near Weimanalo to the east. But they fell on another rock.

A PBY patrol bomber dropped depth charges on the damaged submarine. Sakamaki decides to abandon the ship and tries to blow up the cutout, but even the ship's self-destruct device doesn't work.
The next morning, Hawaiian soldier David Aku captures a Japanese sailor. Sakamaki, the first Japanese prisoner of war of World War II, refused to cooperate with his interrogation, demanding that he be killed or be allowed to commit suicide.
The Japanese military was aware of the capture, but officially announced that all the submarines were missing. The commemorative name of the special combat unit was omitted. On 29 May 1942, five Japanese I Class submarines met about 35 miles northeast of the entrance to Sydney Harbour. E14Y before noon the next morning
Led by Warrant Flying Officer Susumo Ito and Ordinary Seaman Iwasaki, the ship flew a daring reconnaissance mission and circled the USS twice.

Although air raids were observed and reported, no special defense measures were initiated at the port. Many mistakenly believed it was a US Navy plane on a routine training mission. For the Japanese cavalry, it was the latest in a series of reconnaissance flights over Sydney that provided intelligence vital for surprise attacks on several Allied warships peacefully anchored in the harbor. The main targets included the cruiser HMAS.
Scattered outside the harbor entrance, the two submarines were launched early in what some called the 'Battle of Sydney'.
Japan Midget submarines carried two torpedo tubes and two crew members. They displaced 46 tons under water and could reach a speed of less than 19 knots.
Lieutenant Kenshi Chuman and Petty Officer Takeshi Omori did so around 8:30 p.m. However, it didn't get far when the ship's propellers got caught in the anti-submarine net near the aft boom gate. The water disturbance caused by the evasive submarine was soon seen, and at that time the patrol vessel HMAS.

An investigation was ordered. However, When the crew of the submarine realized that they could no longer release the central propellers. choose a hero's death; At 10:37 p.m., a general alarm was raised, removing the charges of sabotage that destroyed their ship.
