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.
The term for small research submarines is "submersible." Submersibles are designed for underwater exploration and scientific research, often equipped with advanced technology for studying marine environments. Unlike traditional submarines, they usually have limited operational depth and are often used for specific missions rather than prolonged underwater travel.
A bomb and some Japanese.
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.
During World War I, several methods were employed to detect submarines, including hydrophones (underwater microphones) and sonar technology, which were still in their early stages of development. Ships also used depth charges and patrolling aircraft to locate and attack submarines. Additionally, the use of smoke screens and listening devices on ships helped in identifying submarine positions. These technological advancements marked the beginning of more sophisticated anti-submarine warfare strategies.
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.
