Japanese Submarine Aircraft Carrier History And Development

The concept of a submarine aircraft carrier may seem like a product of modern innovation, but its history dates back to the early 20th century, particularly in Japan. During World War II, the Japanese Navy explored the idea of combining the stealth of a submarine with the versatility of an aircraft carrier. This ambitious project aimed to create a vessel that could launch and recover aircraft while remaining undetected beneath the surface.

Early Experimentation and Development

In the 1930s, the Japanese Navy began experimenting with seaplane-carrying submarines, which were designed to carry and launch floatplanes. These early vessels, such as the I-5 and I-6, were equipped with catapults to launch the aircraft, but they were not true submarine aircraft carriers. However, they laid the groundwork for the development of more advanced submarines that could carry and recover aircraft.

Chitose and Mizuho: The First Submarine Aircraft Carriers

In the late 1930s, Japan began constructing two purpose-built submarine aircraft carriers, Chitose and Mizuho. These vessels were designed to carry and recover three Aichi E13A1 Jake floatplanes, which were stored in a hangar within the submarine's hull. The aircraft were launched using a compressed air catapult and recovered using a crane. Although Chitose and Mizuho were not entirely successful, they marked an important milestone in the development of Japanese submarine aircraft carriers.

World War II and the I-400 Class

During World War II, Japan's need for a long-range, stealthy aircraft carrier became increasingly pressing. In response, the Japanese Navy developed the I-400 class of submarine aircraft carriers, which were the largest submarines in the world at the time. These vessels were designed to carry three Aichi M6A1 Seiran torpedo bombers, which were stored in a massive hangar within the submarine's hull. The I-400 class submarines were capable of launching and recovering their aircraft while remaining submerged, making them true submarine aircraft carriers.

Operations and Legacy

The I-400 class submarines played a significant role in Japan's naval strategy during World War II. Although they did not achieve any notable successes, they demonstrated the potential of submarine aircraft carriers as a new type of naval warfare platform. The Allies captured two of the I-400 class submarines after Japan's surrender, and they were subsequently studied and reverse-engineered by the United States and the United Kingdom.

Cold War and Modern Developments

In the post-war period, Japan did not pursue the development of submarine aircraft carriers. However, other countries, such as the United States and the Soviet Union, continued to experiment with this concept. In recent years, there has been a resurgence of interest in submarine aircraft carriers, driven by advances in technology and the growing importance of anti-submarine warfare. Japan has not announced any plans to develop a new submarine aircraft carrier, but its historical experience in this area remains an important part of its naval heritage.

Conclusion

Japan's experience with submarine aircraft carriers during World War II was marked by both innovation and challenges. Although the I-400 class submarines did not achieve significant successes, they demonstrated the potential of this concept and influenced the development of naval warfare platforms. Today, Japan continues to operate advanced submarines, but it has not pursued the development of submarine aircraft carriers. Nevertheless, the country's historical experience in this area remains an important part of its naval heritage.
