The Ironclad Specification
What Every Ironclad Module Is Built and Tested To
Specification, not a bill of materials · Ironclad specifies and integrates
Ironclad builds hardened, relocatable compute modules. This sheet states the performance envelope, construction standard, and operating boundary every module is built and tested to. Suppliers are selected, qualified, and integrated by Ironclad; we describe what the module does rather than whose components are inside it.
Enclosure & Structure
| Construction | Hardened welded-steel modular enclosure, purpose-built as a structure — not a repurposed shipping container |
| Wind rating | 250 mph |
| Seismic | Engineered for seismic loading |
| Forced entry / ballistics | Built to Department of Defense forced-entry and ballistic-resistance requirements |
| Scaling | Modular units join through RF-continuous seams to form a single larger facility without loss of shielding integrity across the joint |
| Transport | Relocatable by road, rail, or maritime transport |
Shielding
| HEMP / EMP | HEMP shielded; EMP, EMI and RFI protection engineered to MIL-STD-188-125-1A or -2 as the application requires |
| RF attenuation | 60 dB standard; scalable to 100 dB against NSA 94-106 where required |
| Design approach | Shielding integral to the enclosure envelope rather than an interior cage |
Classified-Facility Construction
| Standard | Built to ICD 705 construction specifications |
| Configurations | SAPF and TEMPEST configurations available |
| Accreditation | Granted by the cognizant authority for a specific site and mission. Ironclad builds to the standard and supports the accrediting process; Ironclad claims no accreditation as held. |
Integration, Test & Production Security
| Integration | Factory-integrated and fully tested in the United States before shipment — delivered commissioned, not assembled on site |
| Production controls | Secured US production facility under access control, with component-level inspection |
| Transit | Transport security plan maintained through delivery |
| Commissioning | Set the module, connect power and fiber — operational in hours |
Asset Classification
| Classification | Equipment, not real property. Not permanently affixed to real estate. |
| Acquisition | Direct purchase order rather than a construction contract |
| Depreciation | Equipment schedule |
| Siting | A pad, not a building — relocatable without abandoning an improvement |
Power
| Standard | Utility power where site capacity is adequate |
| Optional — self-powered | Ironclad-owned generation on a skid alongside the module, inside the Ironclad demarcation |
| Redundancy | N+1 |
| Grid relationship | In the self-powered configuration, grid interconnection is standby only and the deployment places no draw on host grid capacity — no interconnection queue or capacity study gating the schedule |
Network
| Primary | Dark fiber from the cable landing station |
| Diversity | Satellite diversity as an independent second path on separate infrastructure |
| Path integrity | No carrier in the data path |
Cooling & Density
| Air | High-efficiency enterprise air cooling — standard |
| Liquid — optional | RDHx, direct-to-chip, and liquid immersion configurations |
| Mixed configuration | Configurations can be combined within a single enclosure so density scales zone by zone as compute generations change, without a facility-wide retrofit |
| Deliverable density | A function of generation, configuration, networking, cooling, and achieved PUE — sized against a defined workload during solution design |
| Not published | Ironclad does not publish device counts or a fixed devices-per-megawatt figure; such a number is meaningless without the configuration it was measured in |
Compute Platform
| GPU platform | NVIDIA HGX B200 / B300 — Blackwell generation, 8-GPU HGX systems, selected per deployment |
| Interconnect | 400 Gb Ethernet standard; NVIDIA Quantum InfiniBand available for tightly coupled training fabrics |
| Generation policy | Current-generation platforms specified at time of order; prior generations are not offered as new capacity |
Capacity
| Increment | Approximately 1 MW per module |
| Expansion | Added in increments as requirement grows — no re-architecture |
| Tenancy | Single-tenant, bare-metal, physically isolated |
Provenance
| Trust path | No supplier in the trust path — silicon, compute platform, containment, cooling, enclosure, or maintenance — originates outside the United States and allied jurisdictions |
| Hardware origin | US-origin; export-controlled where relevant |
| Sustainment | Delivered through a partner operating in 190 countries, certified to ISO/IEC 27001 and SOC 2 |
| Supplier disclosure | Ironclad describes supplier relationships by capability and credential, not by name |
Security & Sovereignty
| Keys | Customer holds the keys |
| Data in use | Hardware-attested confidential computing; encrypted in memory |
| Operator access | Ironclad has no technical means to read customer data at any privilege level, including administrators |
| Residency | Pinned by data class; asset sited in-country, data under host law |
| Operational control | Customer determines what runs and who is admitted; Ironclad operates infrastructure, not the mission |
Operations
| Monitoring | Continuous monitoring of power, cooling, and system health |
| Reporting | Scheduled uptime and utilization reporting to the customer |
| Lifecycle | Proactive maintenance, vendor management, and refresh planned in advance |
| Service level | 99.95% uptime where contracted |
Certifications
Platforms are designed and built to satisfy the baselines below; certification is scoped and contractually committed to service commencement, because these attestations audit a system in operation. Ironclad distinguishes what is held from what is committed.
| ISO/IEC 27001 | Committed · service commencement |
| SOC 2 Type II | Committed · service commencement |
| NIST SP 800-53 — Moderate | Committed · service commencement |
| CMMC Level 2 | Committed · service commencement |
Scoping
Deployment schedules, density targets, and configuration are established during solution design against a defined workload. Every inquiry is reviewed directly by Ironclad leadership.
