A design for a launcher of electromagnetic missiles for a target 100 km distant is discussed in terms of the time dependence of a current pulse over an aperture. Two issues in implementing this design are: (1) to provide the required current distribution over a small surface element; and (2) to coordinate many such elements in an array. We consider an energy flux per pulse at the pulse launcher on the order of 3 $MUL 10$+$MIN@8$/ J/cm$+2$/ for a pulse duration of 100 fs. If this pulse generation can be synchronized over a surface aperture of 6-m radius, for a train of 10$+6$/ pulses, one transmits a flux to a target at 100 km on the order of 10 mJ/cm$+2$/ per pulse train. Since 1988, Auston, Zhang, and their coworkers have made major advances in providing current over an element of area on the order of 1 cm$+2$/, with demonstrated subpicosecond electromagnetic pulses free of any carrier, some with bandwidths of 10$+12$/ Hz, and some, of less bandwidth, with peak power densities of 64 W/cm$+2$/; there is the promise of much higher peak powers. These advances are outlined. Problems and prospects for coordinating many such elements are discussed briefly.
