US Navy

The United States Navy started a long time ago to protect American ships. Over many years, it grew into one of the largest and strongest navies in history. The Navy uses giant ships called aircraft carriers to move planes across the ocean. They also have submarines that can travel deep under the water without being seen. During World War II, the Navy played a huge part in winning the war in the Pacific. They fought hard battles near islands and kept important supply lines open. After the war, the Navy continued to watch over the world's oceans. They work to keep trade routes safe so that goods can travel to different countries. They also help during times of trouble, like when a big storm hits and people need food or water. Technology has changed the Navy a lot over time. Today, they have computers and advanced sensors that help them see things from very far away. Sailors are trained to work on ships that act like floating cities. The Navy continues to be a major part of the United States military power and helps keep the peace.
