A new North Korean Choe Hyun-class destroyer, a 5,000-ton warship, capsized during its launch. Unable to use modern lifting equipment, engineers resorted to a makeshift method involving balloons and hundreds of workers to refloat the 470-foot vessel. Two weeks later, satellite imagery confirms the ship is upright and afloat in Chongjin harbor, though significantly away from its launch ramp.
