It actually appears as a very new threat.And in South Korea, that threat comes from the North.North Korea’s military power was on display at a recent celebration in the capital, Pyongyang.That included what appears to be a fleet of drones, some of which might already have crossed the border.South Korea’s defense ministry says that since 2014, it has recovered four crashed North Korean drones.One of these small UAVs reportedly flew a reconnaissance mission over downtown Seoul.While these appear to have only taken pictures, some security analysts worry that weaponized drones could come next.Moon Sung-muk with the Korea Research Institute for Strategy in Seoul.We did not expect that North Korea could make such small drones and avoid our radar.South Korea must come up with a new security plan to detect these drones quicker and attack them.And that could start with the attack drones that Shim Hyun-chul and his team are working on.
