Hardened, Relocatable Compute and Command Infrastructure
Ironclad builds and operates hardened, relocatable compute modules for sovereign and defense missions. The module is a purpose-built structure — welded steel, shielded, engineered to classified-facility construction standards, factory-integrated and tested in the United States before it ships. It is delivered as equipment on a pad rather than a construction program on a site.
Ironclad's scope is the infrastructure: the enclosure, the power, the network, the containment, and the sustained operation of all four. The mission — the software, the data, the decisions, and the people admitted to them — remains with the mission owner.
Most Ironclad customers contract with us directly — autonomous systems companies, defense-technology manufacturers, research institutions, and enterprises with sensitive or export-controlled workloads. A single agreement covers the module, its deployment, and its operation.
For programs procured through US federal contracting, Ironclad delivers into established prime relationships on vehicles already in place, so a program office can add capability without adding a procurement cycle. Ironclad is an infrastructure specialist rather than a systems integrator competing for mission scope — that boundary is why commercial operators can hand us the facility problem and keep their own stack, and why primes can bring us onto a program without friction.
Autonomous systems C2 is a distinct Ironclad market. Unmanned and autonomous fleets are commanded from somewhere, and that place increasingly needs to sit close to where the systems are built, integrated, and flown — and to keep working when the grid, the building, and the carrier network do not.
Ironclad is software-agnostic. We do not build mission software or command-and-control applications, and we do not operate the mission. We build and operate the facility those applications run inside.
Sovereign and allied government programs contract reserved capacity on a take-or-pay basis, with data residency pinned by data class. The module sits in-country; the workload stays in the jurisdiction it is required to stay in. Tenancy is single-tenant and physically isolated — never shared with another customer.
Ironclad specifies and integrates; we do not publish vendor part numbers. What follows is the standard every module is built and tested to.
The module is equipment, not a brick-and-mortar building. It is not permanently affixed to real estate, so it can be acquired on a direct purchase order rather than a construction contract, depreciated on an equipment schedule, and relocated without abandoning an improvement. Capital treated as equipment moves faster to authorize, faster to depreciate, and remains recoverable when the mission moves.
Where utility power is available and adequate, modules run on it. Where it is not — or where the interconnection queue, capacity study, or host load makes it a liability — self-generation is available as an optional configuration: Ironclad-owned generation on a skid alongside the module, inside the Ironclad demarcation, configured N+1, with grid interconnection serving as standby only. In that configuration the deployment places no draw on host grid capacity.
Connectivity is specified the same way: dark fiber from the cable landing station as the primary path, satellite diversity as an independent second path on separate infrastructure, and no carrier in the data path.
Modules are built on current-generation NVIDIA HGX B200 and B300 Blackwell platforms in 8-GPU HGX systems, selected per deployment, with 400 Gb Ethernet standard and NVIDIA Quantum InfiniBand available for tightly coupled training fabrics.
Modules are available in air- and liquid-cooled configurations, including RDHx, direct-to-chip, and liquid immersion, which can be combined within a single enclosure so density scales zone by zone as compute generations change. Deliverable density is a function of generation, configuration, networking, cooling, and achieved PUE, and is sized against a defined workload during solution design. Ironclad does not publish device counts or a fixed devices-per-megawatt figure.
Provenance is specified, not assumed. No supplier in the trust path — silicon, compute platform, containment, cooling, enclosure, or maintenance — originates outside the United States and allied jurisdictions. Hardware is US-origin and export-controlled where relevant. Field sustainment is delivered through a partner operating in 190 countries, certified to ISO/IEC 27001 and SOC 2. Ironclad describes supplier relationships by capability and credential rather than by name.
Ironclad platforms are designed and built to satisfy the control baselines below — architecture, documentation, and operating procedures are specified against them from the start, not retrofitted to pass an audit later. Certification is scoped and contractually committed to service commencement, because these attestations audit a system in operation: a Type II report requires an observation window, and an authorization requires something to authorize.
Ironclad distinguishes what is held from what is committed and holds itself to the committed date. Accreditation of a classified facility is granted by the cognizant authority for a specific site and mission; where a program requires accreditation, Ironclad builds to the standard and supports the accrediting process.
Security is specified to the requirement rather than bundled. Standard deployments run access control, monitoring, and Ironclad's own operating procedures. Where a program requires credentialed site and personnel security, it is delivered as an optional configuration by a specialist firm staffed exclusively by former Tier 1 and Tier 2 special-operations personnel — Special Forces, Delta, MARSOC, and SEAL backgrounds. Personnel security requirements are scoped with the program office during solution design.
Requirements are scoped directly with Ironclad leadership. Every inquiry is reviewed by leadership — there is no self-serve onboarding.
