context_page_description: The Sims class destroyers were built for the United States Navy, and commissioned in 1939 and 1940. These twelve ships were the last United States destroyer class completed prior to the American entry into World War II. All Sims-class ships saw action in World War II, and seven survived the war. No ship of this class saw service after 1946. They were built under the Second London Naval Treaty, in which the limit on destroyer standard displacement was lifted, but an overall limit remained. Thus, to maximize the number of destroyers and avoid developing an all-new design, the Sims class were only 70 tons larger as designed than previous destroyers. They are usually grouped with the 1500-ton classes and were the sixth destroyer class since production resumed with the Farragut class in 1932.
  The class served extensively in World War II, and five of the class were lost in the war. Of the five ships lost, four were at the hands of the Japanese and one at the hands of the Germans. The class served on Neutrality Patrols in the Atlantic in 1940-41. Except for Roe, Wainwright, and Buck, the class was transferred to the Pacific shortly after the attack on Pearl Harbor.

All of the ships saw extensive combat service. At the war's end in August 1945, three of the seven survivors were undergoing overhauls that were left unfinished, and were ultimately scrapped. The remaining four seaworthy ships were used as targets during the 1946 Operation Crossroads atomic tests at Bikini Atoll. One was sunk by the first blast, while the other three were sunk as targets two years later after serving as experimental platforms.
