Navy lighterage pontoons

Okay, so picture this - sometimes big ships need to unload or load really heavy things like tanks, trucks, or even other smaller ships. But they can't just do that directly from the big ship, they need something else to help them. That's where navy lighterage pontoons come in.

Navy lighterage pontoons are like big flat rafts made out of metal. They can float on water and have a flat surface on top that can hold really heavy things. They also have special hooks and connectors on the sides that can attach to other pontoons, making them like building blocks that fit together.

So when a big ship needs to load or unload heavy things, they send out some navy lighterage pontoons. The pontoons float over to the big ship and then the heavy things can be loaded on top of the pontoons. If they need more space to hold more heavy things, they can connect more pontoons together like building blocks.

Then the lighterage pontoons and the heavy things float back to the shore. Once they're there, the heavy things can be lifted off the pontoons and loaded onto trucks or other ships.

So basically, think of navy lighterage pontoons as big floating rafts with hooks and connectors that help big ships load and unload really heavy things.
