Submarine Warfare Today describes the different types of submarines in service today, from the giant yet barely detectable ballistic missile submarines to the nuclear and diesel-powered attack submarines that patrol the high seas and shipping lanes. Each entry is illustrated by a full-colour artwork, with accompanying text that describes the submarine's design, machinery, performance and history. There is also a full specifications table for each entry detailing displacement, crew size, weaponry carried, dimensions, speed above and below water.
