Feature: Tactical AI


Prefabricated modular data centres


The integration of AI into defence operations requires a fundamental rethinking of mission-critical and digital infrastructures


Equally, sensitive and critical


infrastructures should be manufactured, controlled and maintained within the UK whenever possible, since in an unpredictable world, robust sovereign capabilities provide maximum security, flexibility, redundancy and continuity.


Key requirements: Security, power and flexible compute AI infrastructure in military applications also faces unique security challenges that require integration from the start. Some of the primary considerations are physical security, electromagnetic protection, Sensitive Compartmented Information Facilities (SCIF) compliance, and data sovereignty. Computing environments must be


hardened against physical threats, incorporating LPS 1175 SR2 to SR8- rated construction systems and NPSA- certified modular walling, to protect against both unauthorised access and environmental hazards. AI systems handling sensitive defence


data require TEMPEST shielding compliant with NSA 94-106 and NATO SDIP-27 standards, protecting against sophisticated electromagnetic eavesdropping and cyber-physical attacks. Solutions should be certified to


meet the requirements of ICD 705 and the NPSA for SCIFs, addressing both physical and technical security standards essential for handling classified intelligence. Sensitive defence data must remain


under complete national control, limiting reliance on cloud-based alternatives and reinforcing the case


for on-premises, UK-manufactured infrastructure. Forward-operating computing


environments require comprehensive security but also power resilience. AI workloads create high power demands, especially where stable grid connections are unavailable. Additionally, several mission-


critical capabilities depend directly on the availability of appropriate computing infrastructure. They include autonomous systems, intelligence analysis and tactical cloud solutions. Unmanned aerial, ground and


maritime systems require sophisticated computing resources for real-time sensor processing, autonomous navigation and collaborative operations across multiple platforms. These capabilities demand high-performance computing close to operations. Modern operations generate large


volumes of data that require AI-enabled processing for automated analysis, pattern recognition, anomaly detection, and predictive analytics. Thus, field intelligence loses value quickly if not analysed promptly. This needs modern tactical cloud capabilities that rely on flexible computing that can move with forces, supporting distributed computing, resilient data storage and secure information sharing across coalitions.


Bridging strategy and execution The UK’s defence AI ambitions present a strong vision for national security. Achieving calls for infrastructure that delivers secure, high-performance computing whenever and wherever missions require.


can deliver the critical link between tactical capabilities and strategic objectives. They enable rapid deployment of AI-ready environments with integrated security and resilience, forming the foundation for an AI- enabled defence sector. Modular data centres have advanced beyond previously offered containerised solutions. Today’s systems are sophisticated, enterprise-grade infrastructures, engineered for secure, mission-critical applications. A commercial-off-the-shelf approach


means solutions can be designed, built, delivered and deployed fast, ensuring a highly adaptable methodology that meets the complex and evolving needs of the digital battlespace. The use of virtual reality in the design process enables customers to explore their environment prior to deployment, fast- tracking specification whilst ensuring confidence in component security criteria. EfficiencyIT’s ModularDC range


is precision-engineered in controlled factory environments, ensuring consistent quality and comprehensive testing. These purpose-built solutions are configured for AI workloads, with integrated high-density power, advanced cooling, and advanced security features optimised for defence. Security is integrated in the core design at source, not added later. Comprehensive security integration, based on BAD (barriers, access, detection) principles, ensures forward-operating SCIFs, and tactical data centres can withstand increased physical and cyber threats. This includes reinforced construction, integrated monitoring, multi-factor access control and coordinated cyber- physical protection. The advantage for deploying


prefabricated modular data centres is significant. Whilst traditional data centres require years to plan and build, the prefabricated modular solutions can be operational in 12-18 weeks. For defence organisations, this speed provides a clear strategic advantage.
