ClassX Video Lessons Youtube Channel Curiosity Stream Locating The Wreck Of A Japanese Submarine | Bright Now
Off the coast of Oahu, Hawaii, a team of maritime archaeologists is on an exciting mission. They are diving to explore what they believe is one of the most significant shipwrecks from World War II: the Japanese Super Submarine, i400. This submarine was a secret weapon that could have changed history. Its power wasn’t just in its crew or weapons, but in its ability to carry three fully functional attack airplanes. These planes could launch surprise attacks and disappear quickly.
Submarines were originally built for attacking ships, but the i400 took this idea further by launching aircraft from underwater. Now, 60 years later, a dedicated team believes they have found the last resting place of this incredible vessel and are determined to locate the i400.
The Hawaii Undersea Research Lab (HURL) is a top deep-sea research facility in the United States. They operate two three-man Pisces submarines that have made important discoveries in the ocean. Each sub can dive for up to eight hours and has emergency life support for up to five days. Their search began in 2002 when they found a Japanese sub that was reportedly sunk just before the Pearl Harbor attack on December 7th.
The team is hopeful as they investigate a sonar anomaly over 1,500 feet deep. As they get closer, they realize they have found a submarine. The first sighting shows a massive hull, surprisingly intact, with visible deck gear that made this sub unique. However, they still need to confirm its identity.
The i400 was the largest submarine built at that time, capable of launching three bombers from the surface and then disappearing underwater. It had a crew of nearly 160 men and was armed with torpedoes and machine guns. The Japanese planned to build 18 of these super subs but only managed to construct three.
The i400’s first mission was to attack the east coast of the United States, targeting New York City and Washington, D.C. However, after Germany fell in 1945, the mission changed to targeting the Panama Canal, but it never succeeded. After the atomic bombings of Hiroshima and Nagasaki, Japan sought peace, and the i400 never completed a mission before the war ended.
On August 28, 1945, the i400 was captured by American forces. Recognizing the potential danger of its technology, the U.S. decided to sink it off the coast of Oahu in 1946. The wreckage created a debris field on the ocean floor, and the HURL team must now confirm the identity of the i400 piece by piece.
After extensive exploration, the team positively identifies the i400, with its original markings still visible. They find the main entrance to the hangar system, which was designed to store the three attack planes. The i400 was a first of its kind in submarine technology, with a complex hangar system that allowed for rapid assembly of the planes.
The i400 was also equipped with anti-aircraft cannons and torpedoes, making it a formidable weapon. The crew’s living conditions were cramped and uncomfortable, reflecting the harsh realities of naval warfare. The Japanese Super Sub i400 set the bar for innovation in military technology, influencing modern submarine design. While we can only imagine what it could have achieved, its legacy continues to impact naval warfare today.
Using materials like cardboard, plastic bottles, and paint, build a model of the i400 submarine. Pay attention to its unique features, such as the hangar for airplanes. This hands-on activity will help you understand the design and functionality of the submarine.
Research another World War II submarine and prepare a short presentation comparing it to the i400. Focus on their technological advancements and roles during the war. This will enhance your understanding of submarine technology evolution.
Participate in a submarine simulation game where you navigate a virtual submarine through various missions. This interactive activity will give you a feel for the challenges faced by submarine crews during wartime.
Engage in a classroom debate on the potential impact the i400 could have had if it had completed its missions. Discuss its strategic importance and how it might have changed the course of history. This will develop your critical thinking and public speaking skills.
Write a short story from the perspective of a crew member aboard the i400 during its missions. Use historical facts to make your story realistic. This activity will help you empathize with the experiences of those who served on the submarine.

[Music] Off the coast of the Hawaiian island of Oahu, a team of maritime archaeologists is preparing to dive on what they believe to be one of the most important wrecks of World War II: the Japanese Super Sub i400. This submarine was a secret weapon that could have changed the course of history. Its unique danger came not from its crew or cannons, but from its cargo: three fully functioning attack airplanes that could launch surprise attacks and vanish in an instant.
Initially, submarines were constructed for anti-ship warfare, but the i400 took that concept further by allowing aircraft to be launched from underwater. Now, 60 years later, this dedicated crew believes they know where the last of these vessels rests and are setting out to find the i400.
The Hawaii Undersea Research Lab (HURL) is one of the leading deep-sea research facilities in the United States. It operates two three-man Pisces subs that have made significant oceanographic discoveries. Each sub can dive for up to eight hours and survive on emergency life support for up to five days. They are continuing a search that started in 2002, when they uncovered the wreck of a Japanese sub reportedly sunk just before the December 7th attack on Pearl Harbor.
The crew is hopeful as they explore a sonar anomaly at a depth of over 1,500 feet. As they approach, they realize they have uncovered a submarine. The first sighting reveals a massive hull, surprisingly intact, with visible deck gear that made this sub revolutionary. However, they still need definitive proof of its identity.
The i400 was the largest submarine ever built at that time, capable of launching three bombers from the surface and then submerging undetected. It carried a crew of nearly 160 men and was armed with torpedoes and machine guns. The Japanese planned to build 18 of these super subs but only managed to construct three.
The i400’s first mission was to attack the east coast of the United States, aiming for New York City and Washington, D.C. However, with the fall of Germany in 1945, the i400’s mission shifted to the Panama Canal, but it never succeeded.

On August 28, 1945, the i400 was captured by American forces. Realizing the potential danger of its technology, the U.S. decided to scuttle it off the coast of Oahu in 1946. The wreckage created a debris field on the ocean floor, and the HURL team must now confirm the identity of the i400 piece by piece.
After extensive exploration, the team positively identifies the i400, with its original markings still visible.
