Title: The Technology of World War II

Author: Sean Sheehan

Chapter: Inventions and Discoveries

· Most major inventions were only used in the United States and Germany.

o Countries such as Japan lacked scientific experience to make advanced technology.

· Radar, created in the 1930s, was being tested in the field in the early years of the war.

· Most ground towers were operated by women.

· Radar advancements allowed for individual aircraft to carry their own radars.

· Radars at sea were able to detect enemy U-boats. This alone was enough to scare off some of these submarines.

· The world has started to move from propeller-powered planes to jets.

· The technology of jet aircrafts quickly spread through all countries involved in the war, but not all of the countries implemented the jets.

In this book, Sean Sheehan explains some of the new technology being developed in WWII. One of the technologies that he talked about was the radar and how it eventually was made portable and was able to be used on individual aircrafts and ships. Another invention was the jet engine that was put on fighter planes. These ideas are similar to any new practical invention because they made fighting much easier for whoever was taking advantage of the technology.
