For all SSBN (also called boomers) which carry ballistic missiles, are nuclear powered, in fact, the N means neclear powered. All attack boots, those Los Angeles class, or seawolf class are nuclear powered. There are other smaller submarines for search and rescue missions, however, are not nuclear powered.
