Multi-wave ECM jammer
Multi-wave ECM jammer is a ship special in Master of Orion.
The Multi-Wave ECM Jammer is similar to the primitive ECM Jammer, except that it spreads its jamming broadcast across the entire spectrum of targeting frequencies. Ships equipped with Multi-Wave ECM Jammers have a chance of misdirecting any incoming missile or torpedo. It is not possible to use both this and the ECM Jammer on the same ship.
