Hanwha Aerospace is expected to sign a third-stage contract Monday with the Polish government and a Polish defense company to export its Chunmoo multiple launch rocket systems to the European nation, industry sources said. The deal, reportedly valued at over 5 trillion won ($3.48 billion), will be signed between Hanwha Aerospace, the Polish government and the country's largest private defense firm, WB Electronics, following two previous deals in 2022 and 2024, according to the sources. The first-stage deal in 2022 was valued at 5.035 trillion won, while the second-stage deal in 2024 was valued at 2.2 trillion won. President Lee Jae Myung's chief of staff, Kang Hoon-sik, is reportedly set to attend the signing ceremony. Lee's office said earlier that Kang had left the country Sunday as a presidential envoy, but did not disclose his destination.
