A naval mine is like a hidden bomb placed in the water. Its job is to destroy ships or submarines. Unlike other underwater weapons that are thrown at a target, mines are left in the water. They wait quietly until a ship or submarine comes close enough to trigger them.

Naval mines can be used in two main ways. They can be used to attack, making it hard for enemy ships to move freely. Mines can also trap enemy ships inside a harbor. They can also be used to defend. This means protecting friendly ships and creating safe areas where enemy ships cannot go.

Mines can be placed in many different ways. Special ships called minelayers can lay them. Other ships can be changed to drop mines. Submarines and even aircraft can also place mines. Sometimes, mines can even be dropped into a harbor by hand.

What are Naval Mines?

Naval mines are often a cheap weapon to make. A basic mine might cost around US$1000. However, some very advanced mines can cost millions of dollars. These expensive mines have many sensors. They can even launch a small rocket or torpedo to hit a target.

Rules for Placing Mines

There are international rules about placing naval mines. Countries must announce when they put mines in an area. This helps civilian ships avoid the danger. The warnings do not have to be super detailed. For example, during World War II, Britain simply said it had mined the English Channel, North Sea, and French coast.
