Several types of bombs were used.
Most notably, the Japanese modified their aerial torpedoes for use in shallow water and these were devastating against non-moving targets.
They used ordinary impact bombs.
They used delayed fuse bombs, where the bomb would denotate a fraction of a second after hitting, so that it had time to penetrate the upper decks and explode inside a ship.
They used small anti-personnel bombs to attack airfields.
They used delayed timer bombs especially against airfields so that the field could not be cleared safely.
The Japanese used bombs to bomb Pearl Harbor, planes to fly over Pearl Harbor to bomb it, and guns to shoot people on foot. I hope this is what you asked. :)
No. It had not been invented in 1941 and the first use was on Japan 4 years later. Regular bombs were used at Pearl.
The attack on Pearl Harbor mainly used aircraft bombs and torpedoes, not guns.
Some historians believe that some of the armor piercing bombs dropped by the VAL dive bombers may have been converted Japanese battleship "armor piercing" 16 inch shells. Otherwise, bombs dropped were conventional armor piercing and general purpose high explosive (HE), and then the real destroyers...the torpedos.
No they didn't. The US dropped the Atomic Bomb onto Japan in 1945 and Pearl Harbor happened in 1941.
Pearl Harbor didn't bomb Japan.
Pearl Harbor
No, there was only one reason that America used the atomic bomb. To cause Japan to surrender. The only other way to get Japan to surrender was to invade the country with infantry, and having seen how stubborn the Japanese fighters were at the little islands they defended in the Pacific, Americans knew that the loss of life on both sides would be horrific. To save American fighting men's lives, they decided to drop the bomb. If Japan had surrendered immediately, America would not have dropped the second bomb.
The Japanese bombed Pearl Harbor in bomber planes, fighter planes, submarines, and torpedo bombers. They also planned to use midget submarines but most didn't make it.
After Pearl Harbor, America was devastated. In an attempt to end the war, they used the atomic bomb against Japan. It worked.
-Reasons to use the Atomic Bomb. Saves lives Saves money Saves time Revenge of Pearl Harbor Keep Russians out of Japan, preventing them from getting Manchuria.
No. Atomic bombs use fission, hydrogen bombs use fusion (and are more powerful)
