Final answer:
During World War I and II, technologies like tanks, machine guns, airplanes, radar, and atomic bombs played a significant role in changing the nature of warfare and outcome of battles. The introduction of this technology led to massive production, innovation, and a transformation in the art of warfare.
Step-by-step explanation:
New Technologies Used During War
Military technology has seen significant advancements over the years, particularly during the major conflicts of the 20th century. During World War I, there was the introduction of many new technologies that are still seen in warfare today. Among these were tanks, machine guns, long-range artillery, and airplanes. These innovations revolutionized warfare and resulted in high casualties and destruction due to the nature of total war. Similarly, in World War II, technological innovation was crucial in determining the outcome of the war. The United States was notably innovative, with advancements in radar, sonar, proximity fuses, computers, and jet aircraft. The most significant technological achievement, however, was the development and use of the atomic bomb, which had only been a theory before the war.
In addition, World War II saw the Allies gaining the upper hand in the Battle of the Atlantic through the use of radar to counter the German U-Boat threat. The rapid shift from pure research to military applications by the British scientific community further highlights the significant role technology played during wartime. These advancements have not only changed the nature of warfare but also altered the relationship between states and scientists due to the necessity of investing in military technology for national security.
