The ocean covers over 70 percent of Earth's surface, it's changing all the time, and it happens to be the Navy's operating environment. To keep the U.S. Fleet safe, to get it where it needs to be for any given global crisis, to get our weapons on the right targets, and all our systems and sensors operating to their best tactical advantage, the Navy must continually collect data from all the world's oceans. A fleet of oceanographic survey ships collects information from the seafloor, the ocean surface and the water column, and our aircraft continually survey the ice conditions where these exist. This supports all types of naval operations on, above and below the ocean's surface. Titanic is one answer.
Attack submarines are another.
Enemy mines already positioned in around the world are a third, and there are many more.
