Historical developments before and during 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, much was developed in response to needs and lessons learned during the war, while others were beginning to be developed as the war ended. Many wars had major effects on the technologies that we use in our daily lives. However, compared to previous wars, World War II had the greatest effect on the 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 final outcome.

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

World War II was the first war where military operations widely targeted the research efforts of the enemy. This included the exfiltration of Niels Bohr from German-occupied Denmark to Britain in 1943; the sabotage of Norwegian heavy water production; and the bombing of Peenemunde.

Military operations were also conducted to obtain intelligence on the enemy's technology; for example, the Bruneval Raid for German radar and Operation Most III for the German V-2.
