Armada and Johnson Controls start building modular AI data centers in Dublin

The first modular AI data center built at Armada’s new Dublin manufacturing operation is complete and headed for Fossefall in Norway. Armada and Johnson Controls announced on November 11, 2026, that Galleon Forge Two had begun continuous production, giving Armada its first European manufacturing operation for infrastructure that customers own and control.

The operation occupies 90,000 square feet within a Johnson Controls manufacturing site and is supported by approximately 700 engineers, technicians and other skilled workers. It is the second Galleon Forge established at a Johnson Controls facility, following the first in Gilbert, Arizona.

Computing and cooling, integrated before delivery

The product coming off the line is Leviathan, a modular data center built at multi-megawatt scale. It combines Armada’s computing infrastructure and software with Johnson Controls’ cooling technology and manufacturing capabilities. The first Dublin unit was engineered, integrated and tested entirely at the factory before its planned delivery to Norway.

Johnson Controls supplies equipment across the cooling system, including coolant distribution units, chillers and building controls. Its contribution includes zero-water cooling technologies for densely packed computing equipment. The companies describe those technologies as designed to reduce energy consumption and noise; they do not give measured savings for the completed Dublin unit.

Armada’s software coordinates the other side of the system. The Armada Platform manages power, cooling and computing across the units and, according to the company, can run open-source or proprietary AI models. That puts management of the physical infrastructure and the computing it supports within the same platform.

With Armada, we're combining that experience with our thermal expertise and manufacturing scale to complete more of the complex integration work in the factory and bring compute online faster and more predictably.

Ownership is part of the pitch

Armada describes the offering as sovereign AI infrastructure: customers own the equipment and control its operation rather than depend on an external cloud. The company’s pitch to European governments and businesses pairs that ownership with regional manufacturing, local workers and a local supply chain. Ownership and where the infrastructure is built are both central to its proposal.

Multiple Leviathan units can also operate as one fleet through what Armada calls its Sovereign SI Grid. The company says this arrangement allows critical workloads to avoid depending on a single site. The proposition therefore extends beyond purchasing individual factory-built centers to managing them together as a distributed system.

For Fossefall, finding European partners was important to that goal. Chief executive Øyvind L. Vesterdal said the standardized, modular approach could shorten deployment timelines and make projects easier to develop with local communities. He also cited clean energy, political stability and a suitable climate as advantages for Nordic AI infrastructure.

One completed unit, a larger manufacturing target

Armada and Johnson Controls are targeting at least 500 megawatts of production capacity in 2027 across their manufacturing operations. That is a future manufacturing goal, not a statement that 500 megawatts of customer computing capacity is already operating. It is also broader than the Dublin facility alone.

The announced expansion includes continuous production at Galleon Forge One in Arizona, expected to begin in early 2027. Plans there cover up to 400,000 square feet of manufacturing space and support for more than 500 jobs. The companies also plan further manufacturing expansion at a Johnson Controls site in Edmonton, Canada.

The concrete customer commitment attached to Dublin’s first unit is smaller: Fossefall’s initial order covers five Leviathan data centers totaling more than 9 megawatts. All five are scheduled for delivery by the first quarter of 2027, with the newly completed unit beginning that order.
