A South Korean defense company is pushing to clinch a deal with Poland to sell its indigenous self-propelled howitzers, military sources said Thursday.

"Samsung Techwin Co. is set to sign a contract with Poland this month to export some 120 units of the K-9 self-propelled howitzers," a source said, asking not to be identified.

Samsung Techwin developed the 155-millimeter howitzer for the country's armed forces in 1998 to replace K-55 howitzers. Equipped with state-of-the-art firing and mobility systems, the K-9 has a maximum firing range of some 40 kilometers.

Under the multi-million-dollar deal, Samsung Techwin will export only the body of the howitzer, with the final assembly to be made in Poland with its own turrets, according to another source.

Other detailed terms of the planned contract are not known, and the South's arms procurement agency, the Defense Acquisition Program Administration, refused to confirm the expected deal.

In 2011, Samsung Techwin sold 350 units of the K-9 howitzer to Turkey on "a technology transfer basis," which called for the South Korean firm to provide parts and technology.

Late last month, Hanwha Group agreed to take over Samsung Techwin, an arms affiliate of South Korea's largest conglomerate Samsung Group, along with three other chemical and defense firms of Samsung. (Yonhap)
