Submarine navigation underwater requires special skills and technologies not needed by surface ships. The challenges of underwater navigation have become more important as submarines spend more time underwater, travelling greater distances and at higher speed.
There are three major types of submarines in the United States Navy: ballistic missile submarines, attack submarines, and cruise missile submarines. All submarines currently in the U.S. Navy are nuclear-powered. Ballistic missile submarines have a single strategic mission of carrying nuclear submarine-launched ballistic missiles.
On a submarine, the bridge is the highest point on the conning tower, to provide for better visual navigation when on the surface. [3] They became standard on United States Navy submarines after 1917, greatly improving the function of the vessels while at the surface.
High-strength alloyed steel is still the main material for submarines today, with 250 to 350 metres (820 to 1,150 ft) depth limit, which cannot be exceeded on a military submarine without sacrificing other characteristics. To exceed that limit, a few submarines were built with titanium hulls. Titanium has a better strength to weight ratio and ...
Other submarine tenders were built by conversions. The demand for submarine bases during World War 2 was so great that many specially built submarine tenders were built. Submarine Tender carried fuel for the submarines, food for the crew, and living quarters for the crew to rest while the sub was being serviced.
Harvesting such data sets from the polar plots and computers (Common to sonar, radar and lidar) allows the CIC crew to plot the data correctly on a chart or map at the correct range and bearing, and to calculate the course and speed of the contact accurately, giving the set a vast expansion to include future positions, given unchanged relative ...
A submarine base is a military base that shelters submarines and their personnel. Examples of present-day submarine bases include HMNB Clyde, Île Longue (the base for France's Force océanique stratégique), Naval Submarine Base Kings Bay, Naval Submarine Base New London, and Rybachiy Nuclear Submarine Base (near Petropavlovsk-Kamchatsky).

Centered is the faded image of the battleship USS New Jersey (BB62), representing the past, and the submarine USS New Jersey (SSN 796) taking the name and her legacy into the future. The devil horns, tail, and wings on the outside of the crest are a reference to the Jersey Devil , the legendary creature said to inhabit the New Jersey Pine Barrens .
