As wars around the world have depleted American stockpiles, South Korea has become a key weapons supplier to US allies in Europe, CNN reports. 

The Stockholm International Peace Research Institute (SIPRI) reveals that South Korea has become the world’s 10th largest arms exporter over the past five years.

The main importer of South Korean weapons is Poland, a country on NATO’s eastern flank that is actively preparing for war with Russia.

Recently, Warsaw finalized a deal to acquire a second batch of 180 South Korean tanks, part of a 2022 agreement that will ultimately allow Poland to expand its arsenal to nearly 1,000 armored vehicles.

The deal is valued at $6.7 billion and includes 80 support vehicles, ammunition, logistics, and training packages for the Polish army.

The agreement covers K2 main battle tanks, considered among the most powerful in the world. South Korea’s Defense Acquisition Program Administration says it includes the tanks’ production by defense giant Hyundai Rotem and the establishment of a production line in Poland for the Polish variant, K2PL.

The overall framework deal is considered the largest in South Korea’s defense industry history. The new armored vehicles will partially replace Soviet-era tanks that Poland has sent to Ukraine for use in the war against Russia. Poland has transferred over 300 tanks, more than 350 infantry fighting vehicles, and armored personnel carriers to Ukraine.

As a NATO member bordering Ukraine, Poland is viewed as part of the Alliance’s first line of defense should Russian leader Vladimir Putin choose to expand his aggression beyond Ukraine.

According to a report by the Wilson Center, Poland has arguably become the most capable military power in Europe.
