Two South Korean companies have signed a $5.76 billion contract with Poland to export tanks and howitzers, Reuters reports citing South Korea's arms procurement agency.

The contract, signed in Poland on Friday, is part of the largest arms deal in South Korea's history struck last month with Poland, which is seeking to bolster its military in the face of a Russian invasion of neighboring Ukraine. Hyundai Rotem Co. will supply K2 Black Panther tanks, and Hanwha Defense, the defense arm of Hanwha Corp, will send K9 self-propelled howitzers to Poland, the Defense Acquisition Program Administration said.

"As defence exports are extremely important in terms of sharing weapon systems, mutual logistics support and strengthening security alliances, this export deal is expected to contribute to our efforts to build solidarity with European countries and expand the boundaries of our security capabilities," DAPA said in a statement.
