Hanwha Defense USA expands US manufacturing with $2.2 billion project

Hanwha Defense USA is preparing a $2.2 billion manufacturing investment at Pine Bluff Arsenal in Arkansas, turning part of the US Army installation into a new production base for artillery ammunition components and extending the company’s role in the US defense industrial base.
The company plans to establish its Hanwha Advanced Manufacturing Campus at the arsenal, where it expects to create close to 400 jobs over seven years. A new administration headquarters has already opened at the site, giving the project a permanent presence several months after the Army selected Hanwha for an enhanced-use lease in January 2026.
The scale of the project has increased sharply since then. The Army originally described Hanwha’s proposal as an investment of approximately $1.3 billion that would create around 200 skilled jobs, meaning the latest plan raises the expected capital commitment by about $900 million and nearly doubles the employment figure.
That expansion points to a broader shift in defense manufacturing, where capital is increasingly flowing toward parts of the ammunition supply chain that received less public attention before constraints in production capacity and critical inputs became a strategic concern.
Hanwha is moving deeper into the 155 mm supply chain
The new campus is expected to focus on 155 mm propellant charges and base bleed units, two product categories that sit behind the artillery shells themselves but have a direct influence on how those rounds are launched and how they perform once fired.
Propellant charges provide the energy required to fire an artillery projectile, while base bleed technology is used to reduce aerodynamic drag and extend the range of certain rounds. By producing both in Arkansas, Hanwha plans to establish domestic manufacturing capability across several stages of munitions production rather than operating solely as a final assembly supplier.
That position helps explain why the project matters to the Army, which said in its January announcement that the facility would bring production of materials used in explosives and propellants into the United States while supporting ammunition including 155 mm artillery shells.
The production challenge extends well beyond the number of shells that can move through a final assembly line, since overall output depends on a network of chemical inputs, energetic materials, specialized components, processing equipment and skilled labor. Expanding capacity at one stage of that system produces limited gains if another part of the chain remains constrained.
Hanwha’s approach places the company more firmly inside that production network rather than leaving it positioned primarily as an overseas supplier. Its parent, Hanwha Aerospace, already operates across international defense markets, but the Arkansas investment brings more of that manufacturing capability closer to the US customer and to the wider domestic ammunition base.
Pine Bluff is becoming part of a wider industrial strategy
The choice of Pine Bluff Arsenal adds another dimension to the project because Hanwha is not building on an isolated greenfield site, but instead placing new manufacturing capacity inside an established military industrial location with significant land and infrastructure already available.
Pine Bluff Arsenal covers approximately 13,500 acres and contains about 660 buildings, according to Army industrial-base planning material, with roughly 5,000 acres identified as developable land. The government-owned, government-operated facility already supports ammunition manufacturing as well as chemical and biological defense activities, giving Hanwha access to an industrial setting that is closely aligned with the type of production it plans to develop.
The enhanced-use lease gives the company access to underused federal property while allowing the Army to generate value from land that is not required for its primary mission. Army officials have said lease consideration can be reinvested into infrastructure at the installation, creating a structure in which private manufacturing investment can also support the government-owned site.
Army officials have since pointed to the Pine Bluff arrangement as a model that could be repeated at other installations, pairing available land and infrastructure with private capital rather than relying exclusively on government-funded industrial expansion.
For manufacturers, that structure may reduce some of the difficulty involved in adding defense capacity at a time when building an entirely new production ecosystem can require extensive infrastructure, permitting, utility access and workforce development. Locating new operations within an existing military industrial site can bring production closer to established defense infrastructure while still allowing a private company to finance and operate much of the new capacity.
The arrangement still carries significant implementation requirements. Environmental reviews, permitting, safety standards and regulatory approvals remain part of the development process, particularly for facilities handling energetic materials, so the pace of construction and production will depend on how those stages progress.
Foreign investment is becoming part of US defense localization
Hanwha’s Arkansas expansion also shows how the idea of a domestic defense supply chain is becoming more complicated, since localization increasingly involves overseas companies placing manufacturing capability, capital and technical expertise inside the United States rather than supplying the market entirely from abroad.
That distinction matters for industrial planning because resilience is shaped not only by corporate nationality, but also by where products are made, how quickly production can increase and whether alternative suppliers and production routes are available when demand rises.
The Army has described the Pine Bluff arrangement as one way to use private investment to address supply-chain gaps while generating additional value from government industrial assets. Its broader Strategic Capital Initiative has placed similar emphasis on public-private arrangements that make greater use of existing Army property and infrastructure.
For Hanwha, the campus provides a larger position within the US defense market and a manufacturing base connected directly to one of the country’s established ammunition installations. For the Army, the project offers a route to additional production capacity without requiring the government to finance every stage of the expansion itself.
The increase from approximately $1.3 billion at the beginning of 2026 to a planned $2.2 billion investment in September shows how quickly the Pine Bluff project has grown in both scale and strategic importance.
If that investment converts into sustained production, the significance of the campus will extend beyond the jobs created in Arkansas. Pine Bluff will stand as an example of how private capital, existing government infrastructure and international manufacturing expertise are being combined to add capacity deeper inside the US munitions supply chain.
