A navy is like a big team of boats and ships that belong to a country. Just like when you play with toy boats in the bath, the navy has real boats that float on the water. These boats are important because they help keep the country safe and can travel far away to visit other places.

Think of the navy as a group of superheroes on water. Each ship is like a superhero with special powers. Some ships can go really fast, some can dive underwater like a dolphin, and others can carry lots of people and things. Together, they work to protect the oceans and make sure everyone is safe.

The navy is also like a big family. The people on the ships live and work together, just like how you spend time with your family at home. They help each other and make sure everything on the ship runs smoothly. This teamwork is very important because the ocean can be a big and sometimes scary place, and they need to look out for each other.
