During World War II, when the V1s and V2s soared in their thousands against London, Antwerp and other targets, they were launched by Germans who had made a technological leap over their Allied scientific counterparts. Ultimately, as the German front fell back, the V launch-sites and factories were overrun. Nevertheless, for a time, the Germans had wielded a revolutionary new weapon that we now know pointed to the future of warfare. This intensely researched book overturns many of the myths about the V-weapons by tracing their development under pressure, their employment in combat, and the massive effect their existence had on operations.
