South Korea’s Hanwha is preparing to pour roughly one billion dollars into a new U.S. plant that will manufacture critical 155 millimeter artillery charges, a move that would hardwire an Asian defense heavyweight into the heart of America’s munitions supply chain. The investment signals how far Washington is willing to go to close its artillery gap, and how aggressively Seoul’s defense champions are positioning themselves as indispensable partners in Western rearmament.
The planned facility is not just another factory, it is a strategic bet on long-term demand for 155 millimeter firepower, from Ukraine-style high-intensity conflicts to deterrence in the Indo-Pacific. By tying U.S. and South Korean production more tightly together, Hanwha is aiming to turn its artillery portfolio into a permanent fixture of American and allied war planning.
Why a $1 billion U.S. plant matters for 155 millimeter firepower
The decision by Hanwha to build a roughly $1 billion plant in the United States to produce 155 millimeter charges lands at a moment when artillery has reemerged as the currency of modern land warfare. The United States and its allies have burned through stockpiles at a pace that legacy industrial bases were never designed to sustain, and a new facility dedicated to 155 millimeter components is a direct response to that strain. By putting heavy capital into U.S. soil, Hanwha is signaling that it expects sustained demand for high-volume shell production rather than a short, crisis-driven spike.
That bet is grounded in a hard reality: America’s own industrial machine has struggled to keep up. Analysts have warned that America War Machine Can Make Basic Artillery Fast Enough What only if it overhauls crumbling infrastructure and outdated machinery, a critique that has pushed the Pentagon to welcome foreign partners into its munitions ecosystem. A billion-dollar Hanwha plant dedicated to 155 millimeter charges would plug directly into that effort, adding capacity without forcing the U.S. Army to wait years for domestic greenfield projects to mature.
Hanwha’s U.S. move and the politics of allied production
Hanwha’s expansion into the United States is not happening in a political vacuum, it is unfolding as lawmakers and defense officials debate how to balance domestic industrial priorities with the need for reliable allied capacity. In Congress, figures like Rep Adam Smith have pressed the administration to align its National Security Strategy with concrete investments that shore up real-world production, not just paper concepts. When a senior Democrat on defense policy is publicly scrutinizing the National Security Strategy and raising questions about programs like Golden Dome, it creates a receptive environment for allied firms that can show up with shovel-ready projects and their own capital.
Within that context, Hanwha’s plan to build a U.S. facility to manufacture 155 millimeter artillery components fits neatly into a broader push for Global defense industrial integration. The company’s willingness to invest heavily in American jobs and infrastructure gives policymakers a tangible example of how allied industry can reinforce U.S. readiness, a point underscored when reports noted that Hanwha plans to build US capacity at the same time Congress is wrestling with long-term munitions funding. For me, the political signal is as important as the steel and concrete: Washington is increasingly comfortable treating trusted foreign suppliers as extensions of its own arsenal.
From K9 howitzers to 155 millimeter charges: Hanwha’s artillery pedigree
Hanwha is not arriving in the U.S. artillery market as an unknown quantity, it is bringing a track record built around the K9 self-propelled howitzer and its associated ammunition ecosystem. The K9 is marketed as the world’s most advanced self-propelled howitzer, and that claim is backed by a growing roster of export customers who have chosen it over European and American rivals. Earlier this year, Hanwha highlighted how the K9 platform, paired with its K10 ammunition resupply vehicle, has become a centerpiece of its global defense portfolio, giving the company deep experience in integrating guns, charges, and logistics into a coherent fire support system.
That artillery pedigree is not just about hardware, it is about scale and reliability. In Europe, for example, Hanwha secured a nearly 1 billion dollar K9 and K10 deal with Romania, a contract that underscored how Jul and Hanwha have turned the K9 into a flagship export. The Romanian package, detailed in a global defense market announcement, shows that Hanwha is already operating at the billion-dollar deal scale that a U.S. 155 millimeter plant would require. When a company is delivering full artillery ecosystems abroad, building a dedicated American facility for charges is a logical next step rather than a leap into the unknown.
U.S. artillery demand: from crisis response to structural surge
The strategic logic behind a new 155 millimeter charge plant becomes clearer when you look at how sharply U.S. artillery demand has climbed. The Army Expects to Make More than a Million Artillery Shells Next Year, a figure that would have sounded implausible before the Ukraine war forced planners to confront what high-intensity combat really consumes. That ramp up is not a one-off emergency measure, it reflects a structural shift in how the United States thinks about stockpiles, surge capacity, and the need to sustain allies in prolonged conflicts.
To hit those targets, The Army has nearly tripled its production of 155 shells in a short span, reopening dormant lines as well as opening new ones to meet the requirement. In one assessment, officials described how the Army Expects Make More Million Artillery Shells Next Year by combining domestic investments with allied support, a strategy that leaves room for companies like Hanwha to plug in with specialized plants. For me, the key takeaway is that a million-shell target locks in a long-term demand signal that can justify a billion-dollar facility focused on 155 millimeter charges rather than a diversified, hedged portfolio.
Inside the 155 millimeter bottleneck: charges, not just shells
Public debate about artillery production often fixates on the visible steel shell, but the real choke point can be the 155 millimeter charge that propels it. Charges require specialized energetics, precise manufacturing, and rigorous safety regimes, and they cannot be swapped in from other calibers or legacy stocks without careful testing. When industrial planners talk about scaling up artillery, they are increasingly focused on the full kill chain, from shell bodies and fuzes to the propelling charges that determine range and accuracy.
That is where a dedicated Hanwha plant could have outsized impact. By concentrating on 155 millimeter charges, the company can target one of the most sensitive bottlenecks in the supply chain, freeing U.S. facilities to focus on shell bodies and final assembly. Earlier analysis of America’s munitions base argued that Jun and America need to confront how their War Machine Can Make Basic Artillery Fast Enough What only if they modernize the least glamorous parts of production, including energetics and charge lines, a point captured in Defense Tech and Acquisition News. In my view, that is exactly the niche a billion-dollar Hanwha facility is designed to fill.
Hanwha’s U.S. strategy: from exports to embedded manufacturing
Hanwha’s decision to build a 155 millimeter charge plant in the United States reflects a broader shift from being a foreign supplier to becoming an embedded part of the American defense industrial base. The company has already signaled that it is weighing new investments in the United States, including a production facility for 155-millimeter artillery shells that would help replenish depleted inventories. That kind of move goes beyond selling finished systems like the K9 and instead commits Hanwha to the long, capital-intensive work of running U.S. factories under American regulatory and labor regimes.
In one detailed pitch, Hanwha executives described how the company is evaluating a U.S. site that could produce 155-millimeter shells per month at a scale large enough to make a dent in current shortfalls, a plan that dovetails with the proposed charge plant. The same reporting noted that the company is looking at how a U.S. footprint could support both domestic requirements and allied needs, positioning the facility as a regional hub rather than a single-customer shop. That strategy was laid out in a profile of how the company is weighing new investments in the United States, and it helps explain why a billion-dollar price tag is politically palatable: Washington is not just buying shells, it is anchoring a long-term partner onshore.
Global defense market ambitions and the Romania example
The U.S. 155 millimeter plant is also a statement about Hanwha’s global ambitions. The company has spent the past decade turning itself into a major exporter across a range of industries, and artillery has been one of its most visible calling cards. Deals like the nearly 1 billion dollar K9 and K10 package with Romania show how Hanwha is using big-ticket contracts to establish long-term industrial relationships, often including local assembly, technology transfer, and training that lock in customers for decades.
In the Romanian case, Hanwha highlighted how the K9 self-propelled howitzer and K10 ammunition resupply vehicle would give Bucharest a modern, NATO-compatible artillery backbone, while also tying Romanian industry into Hanwha’s supply chain. The company framed that agreement as part of its push to further expand its global defense market presence, a narrative captured in the Hanwha further expands global defense market presence announcement. For me, the Romania deal is a useful analog for what a U.S. 155 millimeter plant could become: not just a supplier of charges, but a platform for deeper industrial and strategic integration.
Strategic implications for the U.S.–South Korea alliance
At the alliance level, a billion-dollar Hanwha plant on U.S. soil would mark a new phase in U.S.–South Korea defense cooperation. For decades, the relationship has centered on American forces stationed on the Korean Peninsula and joint planning against North Korean threats. Now, South Korean industry is increasingly helping to arm U.S. partners in Europe and potentially in other theaters, turning Seoul from a security consumer into a security provider whose factories are as important as its frontline troops.
That shift has practical benefits for both sides. For Washington, a trusted ally is absorbing part of the financial and industrial burden of rearming for high-intensity conflict, while also diversifying supply chains away from single points of failure. For Seoul, embedding Hanwha into the U.S. munitions base deepens political ties and creates leverage in future negotiations on everything from technology sharing to export controls. When I look at the trajectory of deals like the K9 exports and the planned 155 millimeter charge plant, I see an alliance that is moving from a traditional security guarantee model to a more reciprocal industrial partnership, one where artillery lines in both countries are part of the same strategic architecture.
What to watch as Hanwha’s U.S. plant takes shape
As Hanwha moves from planning to execution on its U.S. 155 millimeter charge plant, several markers will show how transformative the project really is. The first is scale: whether the facility is sized to cover a modest share of U.S. demand or built to become a major pillar of allied artillery production. Given that The Army is already targeting more than a million 155 shells per year, a plant that can meaningfully support that volume would signal that Hanwha is not just a niche supplier but a core part of the solution.
The second marker is integration. If the plant is tightly linked to U.S. depots, logistics networks, and future artillery programs, it will be harder to unwind in any future political squall, effectively locking Hanwha into the American defense ecosystem. That would echo the way Jul and Hanwha have embedded the K9 into European armies through long-term support and co-production. From my vantage point, the combination of political backing in Congress, clear demand signals from The Army, and Hanwha’s willingness to invest its own capital suggests that the new 155 millimeter charge plant is likely to become a permanent fixture of the U.S. arsenal rather than a temporary wartime expedient.
