Liberty ship

A liberty ship is like a really, really big boat that was used to transport important things during World War II. Think of it like a big delivery truck that could go on water instead of on the road. These ships were very special because they were made very quickly and were cheaper to build than other kinds of ships. They were able to help the United States and its allies bring important things like weapons, supplies, and food to different parts of the world during the war. Without the liberty ships, we might not have been able to win the war!
