Hanwha Aerospace Daejeon Plant Explosion Kills 5, CEO Booked

An explosion at Hanwha Aerospace's Daejeon facility on June 1 killed five workers and injured two during a cleaning operation involving solid rocket propellant residue. The Daejeon plant — a national high-security defense facility responsible for Chunmoo MLRS, L-SAM, and precision-guided munitions — was partially shut down under a suspension order. CEO Sohn Jae-il was booked under the Serious Accidents Punishment Act, and authorities are considering booking Hanwha Group Vice Chairman Kim Dong-kwan. The incident raises questions about safety practices at Korea's largest defense manufacturer.
