Modern U.S. submarines are built by what is known as "Modular" construction. In the early days of Nuclear boats, construction was like any Navy vessel - from the keel up. However, with the advent of the Trident FBM submarines modular construction was developed, and found to be much more advantageous.
Essentially, each major compartment is built individually in separate sections. When completed to a certain point, the sections are brought together (they're constructed on a rail system) and then welded together. All systems are connected as the compartments come together. Seeing each section being built at the Shipyard is a real sight to behold, but not as much as seeing a Trident Submarine on the rails next to an LA class boat. What you actually see above water is only about 1/5 of the boat's actual size - most of it is underwater.
This construction method is much faster than the old way, and is just as strong. Use the link below to see an image of a module of a UK Astute class submarine on its way from a builder to the yards.
