A number of authors lately have expressed proper concern about thereadiness of the US Navy to conduct warfare in a dimension other than the three conventional media: sea, air, and land.' This additional dimension, the electromagnetic spectrum, is as vital a battlefield in wartime as any of the other three, perhaps even more so. While Americans have consistently been in the forefront of the technical development of electronic warfare (EW) equipment, we have not, at the same time, been quick to exploit its operational utility across the entire spectrum of warfare.
