Submarine mines in U.S. harbor defense
Well kiddo, imagine you have a big box with a surprise toy inside. You put the box in your room and make sure no one can get in without your permission. That's how the United States protects its harbors with submarine mines.
Submarine mines are like big boxes filled with explosive surprises designed to stop enemy ships from entering our harbors. They are round and look like big metal balls with wires hanging from them. These wires are connected to a device that can explode the mines when a ship is too close.
The mines lay on the seafloor in hidden locations and wait for a signal to detonate. When enemy ships move too close, the device sends a signal to the mines, which then explodes in a big bang, sinking anything close by.
These mines are very important because they help protect our harbors from enemies who want to sneak in and surprise us. We don't want anyone who means to cause us harm to come into our ports undetected, so we use these mines to make sure they can't get in.
