The AC-130U Spectre is a byword for high-precision fire support. But equipping it with directed energy weapons (DE) will take close air support to an entirely new level. The technological breakthrough needed to get there is a radical $22m superconducting generator which the Air Force will demonstrate by 2009 and which is specifically indended to fit on a C-130. Instead of conventional copper wiring, the generator uses metal foil coated with superconducting material. This can carry very high currents with no loss, making it suitable for high-power uses. Maintaining superconductivity means staying at low temperature, requiring a liquid nitrogen cooling...
