    Of course! Silly me.

    Well, more specifically, they are a lot denser, and use ballast to alter their density relative to the water.

    But they are smaller, right?

    Yea, you wouldn't be interested in one of those.

    If the question was meant to be in earnest. They have tanks which they will lood with seawater until they dive and they have compressed air to remove the water again and have enough buoancy to float

    That's all good, but can these things be used as a weapons platform?

    I bet you can float a firecracker on one. Don't put an M80 on one and flush the toilet.

    like it is said previouslqy it is all about the air filled aerias but shouldnt you also take into acount the shape of the vessel in which upward force of the water is affecting the downward force of gravity on the aeria it has been offered to use

    Did you wash your hands before typing your questions?

    It's just buoyancy. Elementary physics
