BAE Systems, a US Defense contractor, is now testing a High-Powered Microwave (HPM) weapon on sea fairing ships and targets. This device can be pointed at a target, or in the general direction of the target, and effectively knock out electronics in its cone of fire, within range. BAE states, "BAE Systems is developing the High-Powered Microwave (HPM) to provide a means to shut down small boat engines at tactically significant ranges."
BAE's manager of business development, John Perry, touts the worth of the HPM, "the value of the HPM would be its fan of radiation, displacing the need for accuracy, and knocking out up to 30 small boats at a time — allowing other weapons to take it from there. “If you can knock out 50-75% of the engines in a swarm, you can then concentrate on the remainder with lasers or kinetic [weapons]."
Not sure about the effects of the human beings shot with this weapons, . Although it has been tested, the final shape and design has not been released. Future electromagnetic wars sounds a bit friendlier, and welcome, in my opinion.
