In World War II, UM's research grew to include U.S. Navy projects like researching proximity fuzes, PT boats, and radar jamming. By 1950, 21,000 students were at UM. As the Cold War and the Space Race started, UM got many government grants for research and helped to create peacetime uses for nuclear energy. Now, much of that work, as well as research into other energy types, is done by the Memorial Phoenix Project.
