An anonymous reader writes "Not too long ago General Dynamics announced a successful test of their new Trophy Active Defense System (ADS). The Trophy ADS generates something similar to a force field around one half of a vehicle as a direct reaction to incoming fire. From the article: 'The Threat Detection and Warning subsystem consists of several sensors, including flat-panel radars, placed at strategic locations around the protected vehicle, to provide full hemispherical coverage. Once an incoming threat is detected identified and verified, the Countermeasure Assembly is opened, the countermeasure device is positioned in the direction where it can effectively intercept the threat. Then, it is launched automatically into a ballistic trajectory to intercept the incoming threat at a relatively long distance.'"
