Role and use of available technology in World War II

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 to their development as the war ended. Wars often have major effects on peacetime technologies, but World War II had the greatest effect on the everyday technology and devices that are used today. Technology also played a greater role in the conduct of World War II than in any other war in history, and had a critical role in its outcome.

Many types of technology were customized for military use, and major developments occurred across several fields including:

• Weaponry: ships, vehicles, submarines, aircraft, tanks, artillery, small arms; and biological, chemical, and atomic weapons
• Logistical support: vehicles necessary for transporting soldiers and supplies, such as trains, trucks, tanks, ships, and aircraft
• Communications
