What new forms of military technology the united states’ strategy in the pacific theater?

In August, 1919 the British Ten Year Rule declared the government should not expect another war within ten years. Consequently, they conducted very little military R & D. In contrast, Germany and the Soviet Union were dissatisfied powers who, for different reasons, cooperated with each other on military R & D. The Soviets offered Weimar Germany facilities deep inside the USSR for building and testing arms and for military training, well away from Treaty inspectors' eyes. In return, they asked for access to German technical developments, and for assistance in creating a Red Army General Staff.
