Overview
Technology played a significant role in World War II. Some of the technologies used during the war were developed during the interwar years of the 1920s and 1930s. Many were developed in response to needs and lessons learned during the war, and others were beginning their development as the war ended. Wars often have major effects on peacetime technologies, but World War II had a profound and lasting effect on many everyday technologies and devices that are used today. Technology played an unprecedented role in the conduct of World War II and had a critical impact on its outcome.
