An explosion at a Hanwha Aerospace factory in Daejeon, South Korea, killed five people and injured two others on June 1, according to officials. The blast occurred at the defense company's facility, which produces rocket propellant and other defense products, and triggered a large firefighting response. Authorities are investigating the cause, and the company has since suspended operations across all its production sites.
Coverage Comparison
Yonhap News reported the incident in multiple updates, first breaking the news of the explosion and later detailing the casualty count, the company's response, and the ongoing investigations. All reports were consistent on the core facts: five people died, two were injured, and the explosion happened at the Daejeon plant. The reports varied in their emphasis, with some focusing on the immediate response, others on the police investigation, and several on Hanwha Aerospace's operational and safety measures.
Key Claims
Explosion and Casualties
The explosion was reported at 10:59 a.m. on June 1, according to fire and police officials. Fire authorities mobilized about 100 personnel to extinguish the blaze, which was fully under control by 1:07 p.m. The victims included two contract employees in their 20s and three permanent employees—two in their 50s and one in their 30s—as reported by Yonhap. Police later confirmed the identities of all five victims through DNA analysis by the National Forensic Service, and their bodies were to be returned to their families.
Suspected Cause
The explosion is suspected to have occurred while workers were cleaning propellant powder residue from tools used in producing propulsion systems. A company official said, "Various tools are manufactured in the process of producing rocket propellant, and it appears that the explosion occurred while cleaning the propellant residue." Another report suggested the blast may have been caused by propellant used in propulsion systems. The exact cause remains under investigation.
Company's History of Accidents
The facility in Daejeon has a history of deadly explosions. Yonhap reported that an explosion in 2018 killed five people, and another in 2019 left three workers dead. Following those accidents, the company said it invested in automating and systematizing the relevant processes, but a company official acknowledged that the process involved in the latest incident "was not something we initially perceived as posing a great risk."
Operational Suspension
Hanwha Aerospace announced it would suspend operations at all nine of its business sites nationwide for two days starting June 4, marking the first companywide production shutdown since its establishment. The company said the suspension was to conduct special safety inspections, prioritizing a safe working environment over temporary production disruptions. Some essential production processes were exempted from the shutdown. Earlier, the company had partially suspended production at the Daejeon facility after being ordered by labor authorities to halt operations due to the serious workplace accident under South Korea's occupational safety laws.
Financial Impact
The production lines affected by the explosion generated 1.32 trillion won (US$870 million) in revenue last year, accounting for 4.94 percent of Hanwha Aerospace's total revenue of 26.7 trillion won, according to the company.
Investigation and Government Response
Police launched a joint inspection of the factory, involving the Daejeon Metropolitan Police Agency, the fire service, the National Forensic Service, the labor ministry, and the Korea Occupational Safety and Health Agency. Investigators plan to determine the source of ignition and examine whether flammable materials were present at the scene. Labor Minister Kim Young-hoon joined the inspection and vowed to carry out a thorough probe. The Daejeon District Prosecutors Office formed a dedicated investigation team to determine the cause and identify those responsible.
The government also launched a joint inspection of 42 workplaces handling military explosives, as announced by the Defense Acquisition Program Administration (DAPA). The inspection will check safety management related to the manufacturing, storage, and testing of military explosives, and will take legal steps if violations are found.
Company's Apology and Safety Measures
Hanwha Group issued an apology to the victims, their families, and the nation, pledging to thoroughly investigate the cause and prevent a recurrence. Group Chairman Kim Seung-youn said he was "overwhelmed with grief" and instructed the company to form a task force to handle the aftermath.
On June 14, Hanwha Aerospace launched an independent committee to oversee its safety system, comprising 11 external safety experts and two members recommended by the company's labor union. The company also reported investing 247 billion won in 2025 to improve safety, up from 11.4 billion won the previous year, and plans to invest 452.4 billion won this year.
