 The company says that its prototype high-power microwave (HPM) weapon, with an energy focused to within 1 degree, sends an electrical pulse which penetrates through openings in the missile’s metal parts and reaches its computers and guidance system.This energy is powerful enough to damage electrical components and scramble computer chips, causing the missile to fly off course.Raytheon has tested the system at an American airport, but both the company and the airport are unwilling to disclose which one because of a confidentiality agreement.
