Cassin-class destroyer

Four destroyers of the United States Navy made up the Cassin class, all of which served as convoy escorts in the Atlantic in the First World War. They were the first of five second-generation 1,000-ton four-stack destroyer classes that were front-line ships of the Navy until the 1930s, known as thousand-tonners for their normal displacement, while earlier classes were nicknamed flivvers for their small size. The Cassins were the first to carry the new 4-inch/50 caliber gun, and their torpedo tubes rose from six on the Paulding class to eight, which pushed displacement above 1,000 tons and cut speed below 30 knots despite more shaft horsepower. Three of the class served with the Coast Guard on Rum Patrol in 1924 to 1931, and all were scrapped in 1934 and 1935 to comply with the London Naval Treaty. Bath Iron Works in Maine built two of the four, Cassin and Cummings.
