The Naval Act of 1936 authorized the first new battleship since 1921, and USS North Carolina, was laid down in October 1937. The Second Vinson Act authorized a 20% increase in the size of the Navy, and in June 1940 the Two-Ocean Navy Act authorized an 11% expansion in the Navy. Chief of Naval Operations Harold Rainsford Stark asked for another 70% increase, amounting to about 200 additional ships, which was authorized by Congress in less than a month. In September 1940, the Destroyers for Bases Agreement gave Britain much-needed destroyers—of WWI vintage—in exchange for United States use of British bases.[117]
In 1941, the Atlantic Fleet was reactivated. The Navy's first shot in anger came on 9 April, when the destroyer USS Niblack dropped depth charges on a U-boat detected while Niblack was rescuing survivors from a torpedoed Dutch freighter. In October, the destroyers Kearny and Reuben James were torpedoed, and Reuben James was lost.[118]
