Nova pinpoints the beginnings of radar in Nova: Echoes of War. Though eclipsed by bigger inventions like the atomic bomb, radar helped secure victory after victory in World War II. Originally offering only a warning, the technology soon evolved into a complex device capable of guiding bombs to specific targets. In the water, air, and on land, electronic machinery advanced the art of warfare. Nova neatly encapsulates the history of radar.
