Vietnam chooses South Korean K9 Thunder: a new stage in defense cooperation

 

 K9 Thunder

In January 2025, it became known about the signing of a historic contract between the South Korean company Hanwha Aerospace and the government of Vietnam for the supply of 20 K9A1 Thunder self-propelled howitzers. The deal, worth about $300 million, not only strengthens Hanoi's military capabilities, but also marks the first time South Korean weapons have been exported to a communist country, opening a new chapter in bilateral relations.  

According to the announced terms, Vietnam will receive a batch of upgraded K9A1 self-propelled howitzers, which are considered one of the most advanced artillery systems in the world. These vehicles are equipped with 155 mm guns with a firing range of up to 40 km, an automated fire control system and increased mobility, which makes them a key element of modern artillery. The contract probably includes training for the Vietnamese military, maintenance and the supply of spare parts, although the exact delivery dates have not yet been disclosed.  

For South Korea, this deal is a breakthrough into the market of countries with a communist regime. Previously, Seoul had focused on democratic partners such as Poland, Norway and Turkey. Exports to Vietnam, where the Communist Party dominates, demonstrate the flexibility of the South Korean defense industry and the desire to strengthen its position in the Asia-Pacific region.  

Vietnam, in turn, is actively modernizing its army amid territorial disputes in the South China Sea. The purchase of the K9 Thunder enhances its artillery fleet, which previously included mostly outdated Soviet and Russian models. It is also a signal of the diversification of military ties: previously, Hanoi cooperated with Russia and China, and now it is looking for alternatives in the West and in Asia.  

The deal is gaining special weight against the backdrop of China's growing influence in the region. Strengthening ties between Seoul and Hanoi can be seen as a step towards balancing forces, although both sides avoid open confrontation with Beijing. For the United States, South Korea's traditional ally, it is also an opportunity to increase pressure on China through partners in Southeast Asia.  

The success of the contract with K9 Thunder can become the basis for expanding military-technical cooperation. Experts do not rule out that Vietnam will be interested in other South Korean developments, such as warships, drones or air defense systems. For Hanwha Aerospace, this is a chance to gain a foothold in a region where demand for advanced weapons is growing due to tensions over Taiwan and the South China Sea.
