The weapon described is a depth charge.
Submarines todaee are used for underwater exploration,funn,new life underwater.
They are used for scientific research as well as warfare. Smaller submarines were used for scientific research (underwater animals, plants, etc.)

World War I submarines were primarily used to locate and attack surface cargo and warships.
Submarines are built with a special design that allows them to be faster underwater. Submarines can be used during a war as a way to sneak up to enemy lines in the water, but still stay hidden.
Yes, they used Midget submarines to attack the harbor bridge. The attack lasted 4 minutes but every shot was well short of it's initial target.
There were several bombs used on Pearl Harbour it was not a one bomb attack.

A torpedo is a self-propelled underwater weapon with an explosive warhead. It can be launched by aircraft, ship, or submarine, against surface vessels or submarines. Torpedoes use monopropellants (e.g., Otto Fuel) as engine fuel, which has its own oxidizer, since there isn't any oxygen to sustain a combustion engine underwater otherwise.
It uses echo location for all underwater submarines and when the signal comes back you will be able to see whats in front of you.
sonar is a device for detecting objects underwater by emitting sound waves and analyzing the echoes that bounce back. It is commonly used in navigation, fishing, and underwater mapping.
Sonar, which stands for "sound navigation and ranging," is the method used to find objects underwater by emitting sound waves and measuring the time it takes for them to bounce back. This allows for the detection and location of underwater objects like shipwrecks, submarines, and marine life.
