The Germans were also believed to have in development a supersonic rocket, the V-3, capable of reaching New York City. If the big brains of the Reich, led by boy genius Wernher von Braun, could put a nuclear payload on the New York rocket, they might win the war. German scientists, it turned out, were not close to completing such a rocket and had already given up hope of developing an atomic bomb, but in June 1944, Allied intelligence did not know this.
