Okay, so imagine you are playing hide-and-seek at night with your friends. You are "it" and need to find your friends who are hiding in the dark. But you can't see them because it's too dark outside. What do you do?
You might use a flashlight to help you see better, right? Well, the German Night Fighter Direction Vessel Togo was kind of like a really big flashlight that helped German fighter planes find enemy planes at night during World War II.
The Togo was a big ship that had lots of radios and special equipment on board. The radios could talk to the German fighter planes and give them directions on where to find the enemy planes. The special equipment could also help the Germans figure out where the enemy planes were flying by listening to their radio signals.
So, just like how you use a flashlight to find your friends in the dark, the Togo helped German fighter planes find enemy planes in the dark night sky during the war.
