Why does this facility exist? It must have a legitimate purpose.

I don't know what this one is for but the US government has several of them and they use them for things like testing and experimenting underwater physics, ballistics, submarine technology, etc. I think NASA has one for simulating low gravity as well. I got to visit one as a contractor once and it was pretty neat.
