Poland on Wednesday signed basic deals with South Korea to acquire Korean-made FA-50 light attack fighters, K2 battle tanks and K9 self-propelled howitzers.

Under the "framework contracts," Poland is to procure 48 FA-50 jets, 980 K2 battle tanks and 648 K9 howitzers, the Polish government said, describing the deals as one of the country's "most important and largest" defense orders in recent years.

The contracts came as Poland has been striving to "fill the gap" created by its delivery of weapons systems to Ukraine that has been fighting against Russia. Warsaw did not disclose its cost estimates for the contracts.

The delivery of 180 K2 tanks is expected to begin this year, while 800 K2 tanks will be manufactured in Poland. Poland also plans to first purchase 48 K9 howitzers and order 600 more afterwards.

Poland's Ministry of National Defense said earlier that the country plans to buy 48 FA-50 light attack fighters, with the first batch of 12 jets to be delivered in the middle of next year.
