Aviation submarine I 400
Aircraft carriers were widely used during World War II, especially in the Pacific Ocean. At the same time, the submarine is also an indispensable weapon at this time, and the combination of the two is the submarine aircraft carrier. It can be understood that the aircraft carrier has the ability to dive, and it can also be understood that there are more planes on the submarine. Among them, the most famous is Japan's Iraqi 400-class submarine, at least it is the largest.
The history of aviation submarines and the planned voyage of Japan at that time.
The air submarine was not an advanced thing in World War II. As early as World War I, air submarines appeared, and the first country to use them was Germany.
19 15, the Germans put the FF 29 water reconnaissance plane on the U 12 submarine. In fact, the submarine is used to transport the plane to the predetermined area first to increase the attack radius of the plane, and the submarine cannot dive during transportation. There were many such examples at that time.
1934, the French took the lead in building a real aviation submarine, namely the Sukov submarine. Its underwater displacement has reached 4304 tons. In addition to the torpedo weapon, it is also equipped with a 203mm double turret.
Behind the bridge is a hangar, which can carry a MB4 1 1 seaplane, but it is rarely used. This hangar is generally used as a warehouse. After the Battle of France, the Sukov belonged to free France. It collided with an American merchant ship and sank in 1942.
Let's look at Japan again. At this time, we have reached the point of no return. Isoroku Yamamoto plans to attack the west coast of the United States, even if it does not have the ability to launch a large-scale attack, it will also attack strategic locations such as naval positions.
Therefore, aviation submarines have always been on the development list of the navy. Before the birth of I-400, Japan also developed many aviation submarines, but they were small and could only carry one plane, with little effect. In this case, the production plan of Iraqi 400-class aviation submarine is put on the agenda.
2. Performance of Iraqi 400-class aviation submarine.
The 400-class Iraqi submarine has an underwater displacement of 6,560 tons, far exceeding the previous Sukov submarine, with a surface speed of 18.7 knots, an underwater speed of 6.5 knots and a battery life of up to 4 months. The bow of the ship has eight 533mm torpedo tubes equipped with 20 torpedoes.
There are 140mm naval guns on deck, plus 10 25mm anti-aircraft machine guns. From the appearance, the I -400 is not completely symmetrical. Its bridge is shifted to the left by 2. 1 m, and its hangar is also shifted to the right by 0.6 m.. In order to keep balance, there are also unstable situations when diving.
Iraq's Class 400 hangar is cylindrical, with a length of 35 meters and a diameter of 4 meters. It is directly equipped with three refueling systems. After the hangar is opened, the extension zip line will drag the prepared aircraft to the catapult, and a buoy will be installed on the aircraft during this period.
The catapult on the Iraqi 400 class is powered by compressed air and can eject a plane with a maximum of 5 tons. There is a lifting device at the front of the deck to recover the surface of the returning plane.
The aircraft used by the I -400 is an attack aircraft on Shimizu, which was born as an attack aircraft on an aviation submarine. In the hangar, the wings on both sides rotate 90 degrees and turn back.
The first prototype was completed in 1943, and by the end of the war, a total of 26 were produced. A plane can carry 800 kilograms of bombs or torpedoes. Because the Iraqi 400 has not participated in any actual combat, the Qingfei water attack aircraft has also been eating ash in the hangar.
3. The extension of Iraq's 400-class aviation submarine.
After the completion of the 400-class submarine in Iraq, Japan has lost the initiative, and the United States is constantly strengthening the air defense project on the west coast. In the plan, the Iraqi 400 submarine was prepared to attack the Panama Canal, but the plan was postponed due to the lack of qualified pilots.
However, due to the continuous defeat of the navy, the front of the Iraqi 400-class aviation submarine has been shrinking. Coupled with cautious psychology, the three Iraqi 400-class submarines that have been completed have never participated in actual combat.
After the war, three Iraqi 400-class submarines and some scale models (Iraqi 13, which can only carry two fine wind attack aircraft) were towed away by the Americans. Although it is not very practical, it is also full of sense of science and technology, which has attracted the attention of the Soviet Union. After discovering that the behemoth on the water supply was targeted, the United States hastily studied it for a period of time and directly regarded it as a target ship.
