South Korea has developed an advanced electromagnetic pulse device that can be deployed on the battlefield to paralyze enemy computers, a defense official claimed Monday. Electronic bombs have been something of a Yeti in the defense industry, widely discussed by experts but never seen to exist.

Park Chang-kyu of the Agency for Defense Development was asked by ruling Grand National Party lawmaker Kim Hak-song to brief the Defense Committee on the progress of EMP development. Park replied, "We feel we can make use of it in wartime if the military makes such request."

Park claimed the power of the device is "considerable."

Turning to North Korea's GPS jamming attack on Friday that hit some parts of northwestern Seoul, Kwon O-bong of the Defense Acquisition Program Administration said, "Because we have a special code for the military, it is unlikely to be affected by such an attack, but there are some weapons that do not require a special code, so we're looking into ways to correct it."
