On a moonless night in January 1991, a dozen US aircraft appeared in the skies over Baghdad. To the Iraqi air defenses, the planes seemed to come from nowhere. Each aircraft was more than 60 feet in length and with a wingspan of 40 feet, yet its radar footprint was the size of a ball bearing. Here was the first extensive combat application of Stealth technology. And it was devastating.

Radar has been in use since the 1930s and was essential to the Allies in World War II, when American investment in radar exceeded that in the Manhattan Project. The atom bomb ended the war, conventional wisdom has it, but radar won it. That experience also raised a question: could a plane be developed that was invisible to radar? That question, and the seemingly impossible feat of physics and engineering behind it, took on increasing urgency during the Cold War.

Combining nail-biting narrative, incisive explanation of the science and technology involved, and indelible portraits of unforgettable characters, kimmerses readers in the story of an innovation with revolutionary implications for modern warfare.
