It could travel an amazing 20,000 meters at 48 kt or 40,000 at 36 kt. warhead, and by using oxygen as the oxidizer instead of air, it had incredible speed and range. This enormous torpedo could be carried only by surface ships. Japan’s big ace in its planning was the Type 93 torpedo, which Morrison later called the Long Lance. battleships crossed the ocean, they would undergo frequent torpedo attacks from submarines, surface ships, and aircraft. Japan focused on the traditional equalizer in sea battles, the torpedo. To address this imbalance, the Japanese planned to reduce the U.S. After the naval treaties of 19, Japan knew that if it had to fight the United States, its battleships would be outnumbered. There, the battleships of the two sides would wage a climactic battle that would decide the war. battleship fleet had long called for waiting for the fleet to steam into Japanese waters, and then destroy it. Japan’s war plans for dealing with the U.S. The front connection broke slightly earlier than the rear connection, tipping the torpedo down. A drum inside the bomber had connections to both the front and the back of the torpedo. The problem with torpedo drops from twin-engine bombers at sea is the need to tip the nose down. Two-engine torpedo bombers also used a drum spooling system, but it worked differently and had a different purpose.

As it did so, however, it kept upward resistance on the nose of the torpedo, preventing the nose from rotating down too much. As the torpedo dropped, the wire played out. The rest of the wire was wound around a drum attached to the Swordfish torpedo bomber. They attached a wire cable to the nose of the torpedo.

In 1995, however, a pilot on the Taranto mission revealed that the British had used an entirely different technology. Later, many argued that the Japanese, being mere imitators, must have copied the technology that the British used in their shallow-water attack at Taranto Harbor a year earlier. Kimmel called the big fins “a device which all the brains in our own Navy Department, who had been seeking such a solution, had been unable to arrive at.” Neither these guesses nor Kimmel was correct. In Congressional hearings on Pearl Harbor, Adm. Again with no evidence or aerodynamic analysis, they guessed that the big tail fins had pulled the torpedo’s nose up so that it would not dive so deeply. With no evidence or aerodynamic analysis, the Navy guessed that the big tail fins had been the key to the Japanese torpedo attack. These were again made of metal covered with wooden gloves that snapped off at water entry. The Navy also saw that there were two smaller fins near the front of the tail cones. These big wooden fins, which were fitted over smaller metal fins, broke off when the torpedo hit the water. They saw that the dropped torpedoes had big wooden fins at the back of their tail cones. Navy examined the remnants of Japanese torpedoes. 7, 1941, Japan proved that it had mastered shallow-water torpedo strikes. Playing out from a drum attached to the airplane, the wire exerted upward resistance on the nose, keeping it from rotating downward too steeply.

They attached a wire to the torpedo’s nose.

The British used an entirely different system for their shallow-water attack at Taranto Harbor a year earlier.

It allowed the aircraft to drop their torpedoes from an altitude of 66 feet (20 m) and at a speed of 185 mph (160 kt, 300 km/h).

This would not be possible if the torpedo were rolled when it hit the water.

This allowed the torpedo’s horizontal rudders to be used to pitch the nose up immediately on impact with the water.

They ensured that the torpedo dropped without roll.

These were gyroscopically driven ailerons.

The enabling innovation was small wooden fins near the front of the tail cone.

The big stabilizing fins at the rear of the tail cone were an older modification unrelated to this problem.

They needed to limit the initial plunge so that the torpedoes would not strike the bottom mud.

The Japanese had to modify their Type 91 Modification 2 aerial torpedoes for the Pearl Harbor attack.
