One of World War II's most crucial secret weapons was the Variable Timing, or V-T, fuze. This technological innovation was made possible by work beginning in 1942 by the newly formed Johns Hopkins University Applied Physics Laboratory. While the V-T fuze proved a great success in skies over the Pacific and over England, it would turn out to be just as devastating on land. A version of the shell produced for the Army pounded counterattacking Nazi troops during the Battle of the Bulge, helping to halt the German assault and cementing the Allied victory in Europe.
