Do submarines always travel underwater?

How shallow can a submarine go?
A nuclear submarine can dive to a depth of about 300m. This one is larger than the research vessel Atlantis and has a crew of 134. The average depth of the Caribbean Sea is 2,200 meters, or about 1.3 miles. The average depth of the world’s oceans is 3,790 meters, or 12,400 feet, or 2 1⁄3 miles.
Why can’t you shoot in a submarine?
Because standard bullet ammunition does not work well underwater, a common feature of underwater firearms is that they fire flechettes instead of standard bullets. The barrels of underwater pistols are typically not rifled. The lack of rifling renders these weapons relatively inaccurate when fired out of water.

Why do submarines come to the surface once every few days?
It lets the sub’s crew have a view of the surrounding horizon while the sub remains submerged. A submarine comes to the surface once every few days (or even more frequently than that), not only to get a fresh supply of atmospheric oxygen from above the water’s surface, but also to dispose of the waste gases that it produces onboard.

What are submarines used for?
