Poland is set to buy rocket launchers in its latest arms deal with South Korea, following shipments of tanks and howitzers, as it ramps up arms imports after Russia's invasion of Ukraine, South Korean officials said on Wednesday.

Poland is expected to sign a deal with Hanwha Defense, the defence unit of South Korea's Hanwha Corp this week, to buy K239 Chunmoo multiple rocket launchers, officials said.

Under the contract, South Korea will supply 288 multiple rocket launchers worth $6 billion, the Yonhap news agency reported.

Hanwha Defense declined to confirm the details of the contract when contacted by Reuters, saying the deal had yet to be closed.

"The contract could be signed as early as this week," an industry source said on condition of anonymity.

The expected agreement comes as South Korean companies shipped the first batch of tanks and howitzers to Poland.

The two countries signed a $5.8 billion contract in Warsaw in July in a deal that Poland said was a key part of its effort to beef up its military following Russia's invasion of Ukraine.

The Feb. 24 invasion, which Russia calls a "special military operation," has raised security fears among many former eastern bloc countries, and NATO member Poland has vowed to boost defence spending to 3% of gross domestic product and to more than double the size of its army.

Hyundai Rotem Co. said its first shipment included 10 K2 Black Panther tanks, among 180 to be delivered by 2025. Hanwha Defense said it was sending 24 units of K9 self-propelled howitzers, among 212 to be shipped by 2026.

Poland has also agreed to buy 48 FA-50 fighter jets from South Korea. Mariusz Blaszczak, Poland's defence minister, said in a July media interview the aircraft would be delivered next year.
