The American Destroyer USS Fletcher 1942

When, in the early 1930s, the Americans began modernizing their navy, they considered the replacement of old destroyers from the Great War as one of the most urgent tasks. However, the new projects, disappointed and dissatisfied the sailors. Some of these vessels were heavily overloaded (e.g. Sims class and early Benson ships), as a result some of the weaponry had to be removed. By proceeding with the design of subsequent series of destroyers, efforts were made to respect the Treaty restrictions (London, 1936). The originally formulated requirements envisaged a destroyer with a displacement of 1,600 tons and armament consisting of not less than 4.5-inch (127 mm) guns and 10 x 533mm torpedo tubes and a speed of 36 knots. There were six variants of vessels slightly different from earlier Benson and Sims classes. It soon became apparent that additional requirements could not be met within the limits of this displacement. This mainly concerned making space for a 28-mm quadruple automatic cannon and more powerful ASuW weapons. 156 profiles, B2 drawing sheets
