Destroyer class of the US Navy

Four destroyers in the United States Navy comprised the Cassin class. All served as convoy escorts during World War I. The Cassins were the first of five "second generation" 1000 ton four stack destroyer classes that were front line ships of the Navy until the 1930s. They were known as "thousand tonners" for their normal displacement, while the previous classes were nicknamed "flivvers" for their small size, after the Model T Ford.

The increase in normal displacement to over 1,000 tons was due to the desire to combine a heavy armament with a substantial cruising range. The US Navy at the time had only three modern scout cruisers of the , so the destroyers had to double as scouts. The engineering arrangement of two shaft direct drive turbines was similar to some previous ships, but the poor performance of early cruising turbines caused a reversion to reciprocating engines for cruising. Hulls 43 and 44 had a triple expansion engine that could be clutched to one shaft for cruising; the other pair of ships had a similar arrangement on both shafts. The ships were commissioned 1913–17. As the type developed the gun armament of four 4 inch (102 mm) guns remained the same, torpedo armament greatly increased, and displacement rose by about 100 tons. The Cassin and Aylwin classes had eight 18 inch (450 mm) torpedo tubes in twin broadside mounts, two mounts on each side. The O'Briens introduced the torpedo to the US destroyer force, but the number of tubes remained at eight. In the Sampsons, torpedo armament was increased to twelve 21 inch (533 mm) tubes by replacing the twin mounts with triple mounts.
