Explosion at Hanwha Aerospace plant in South Korea kills five
A blast and fire at Hanwha Aerospace’s Daejeon plant killed five workers and injured two, renewing scrutiny of a site that has seen fatal explosions before.
The blast tore through Hanwha Aerospace’s Daejeon facility in Oesam-dong, Yuseong District, killing five people and injuring two others at a plant that makes aircraft engines, space launch vehicle engines, weapons and ammunition. The fire was reported at about 10:59 a.m. on June 1, and firefighters said the main blaze was out by about 1:07 p.m.
About 30 emergency calls came in from people who heard a loud explosion and saw smoke rise from the complex. Early reports suggested the blast may have involved rocket propellant, and one account placed it in a cleaning room while another pointed to a laboratory area. Authorities said seven workers were on duty in the area when the explosion occurred.
The deadly fire put immediate pressure on a facility already central to South Korea’s defense manufacturing base. Hanwha Aerospace’s Daejeon plant handles large propulsion system development and propellant charging, work that carries obvious risks when production is pushed hard. The accident is now drawing national attention not only because of the deaths, but because it exposed the vulnerability of a security-designated site that is supposed to operate under tight control.
Hanwha Aerospace and Hanwha Group apologized, expressed condolences to the victims and their families, and said they would fully investigate the cause. The companies also pledged support for the two injured workers. President Lee Jae-myung ordered government officials to mobilize all available resources for rescue efforts and demanded a thorough investigation and measures to prevent a repeat.
The tragedy also reopened painful memories at the same Daejeon plant, where fatal explosions occurred in May 2018 and February 2019. Those earlier rocket propellant-related accidents killed multiple workers, and the recurrence has sharpened questions about whether oversight at the plant has kept up with the demands of a defense sector under pressure to scale up quickly.
For Daejeon, the losses reach beyond the factory floor. The plant sits in a city that has already seen the consequences of repeated industrial disasters, and each new explosion deepens anxiety among workers, families and residents who live near South Korea’s expanding defense industrial base.
