The submarine, first introduced to America's fleet in 1900, is today a 300-foot-long, 30-foot-wide vessel filled with some of the world's most sophisticated technology and courageous, skilled, all-volunteer personnel. In each submarine, over 100 crew members work together for months at a time to protect U.S. interests around the world. Written by an outstanding team, United States Submarines contains essays on submarine history and today's submariners, focusing not only on the subs, torpedoes, and related technologies but especially on the people who make it all work. Full-color and vintage photography, portraits, recruiting posters, and historically inspired paintings complement the riveting text.
