Project history

12 destroyers of the FY1937 program originally were planned to build under slightly changed project of Benham class, but after long-term discussions on the General Board supporters of strong artillery were possible manage on returning the fifth 127mm gun at the expense of reduction of number of quadruple TTs to 3. Designing of new destroyer has begun in spring of 1936. Originally her standard displacement was defined "contractual" 1500t, however in May, 1936 the Senate ratified the total document of London Naval Conference according to which upper limit of destroyer displacement was lifted to 3000t. By this moment design works were at that phase when significant changes were not represented possible to made, therefore standard displacement of new destroyer has increased at 70t: simply real overload included in the design initially was officially claimed. The armament arrangement of new destroyer repeated accepted on Mahan class. The main difference was that all main guns were installed on base ring mounts (and No1, 2 and 5 guns in fully enclosed mounts). Occurrence of new Mk 37 fire control system became the important innovation. Besides, in addition to three TT banks also four spare torpedoes were available.

When the first ships have gone out to trials, it has appeared, that the building overload reaches 120t and stability is very poor. Besides, experience of service in the conditions of Northern Atlantic revealed that destroyers with aside TT arrangement had susceptibility of the their strong corrosions and risk of damage by blows of waves. 25.9.1939, soon after the commissioning of the first ships of Sims class, Secretary of Navy has approved dismantle aside TT banks and transference of one of them to centreline and, besides it, stowage of 60t of ballast. Freed TTs have been installed on Atlanta class cruisers. Many destroyers were outfitted already with the changed arrangement of TTs, and already completed ships changed arrangement of TTs in the summer of 1940.
