What G3 Systems Limited does

G3 Systems Limited is a UK-based engineering and infrastructure solutions company that designs, manufactures, and sustains modular containerised infrastructure and deployable systems for defence and government clients operating in demanding, remote, and operational environments. Founded in April 2001 and now in its 25th year, the company serves clients including the UK Ministry of Defence (DE&S), Netherlands Ministry of Defence, the Royal Navy, the UK Foreign, Commonwealth & Development Office (FCDO), and Permanent Joint Operating Bases (PJOB) across Europe, Africa, and the South Atlantic. Headquartered at Portland, Dorset with a 12,000sqm in-house integration facility at Osprey Quay/Weymouth, G3 Systems is a subsidiary of US-based Intrepid Global Solutions LLC.

The company's product portfolio spans four integrated capability areas: Deployable Infrastructure (ISO-compliant modular containerised systems integrating mechanical, electrical, environmental control, power, and specialist payload fit-outs for command and control, UAV support, medical, and engineering applications), Construction (end-to-end delivery including new-build, refurbishment, and overseas infrastructure projects), Facilities Operation & Maintenance (integrated asset management with CAFM/MIS-enabled operations), and Critical Support Services (through-life support, global logistics, and fire and emergency response). Named programmes include the WTB contract (€100M Netherlands MOD programme covering 418+ flatracks and 270 specialist containers with a 15-year support phase), NavyPODS (Royal Navy modular maritime capability), TCDA (tactical containerised dog accommodation), DEW (Deployable Engineering Workshops with rolling life-extension programmes), and MRBT (Mobile Roller Brake Testing systems under Project Amphora).

G3 Systems generates revenue through a mix of one-time hardware sales (deployable infrastructure manufacture and delivery), managed services (long-term facilities management and through-life support contracts), and construction projects (recognised on a percentage-of-completion basis). Distribution is exclusively direct to enterprise and government clients via competitive tendering, framework agreements, and preferred supplier arrangements; pricing is bespoke and quote-based with no public list pricing, and sales cycles are long and enterprise-focused, requiring security vetting and multi-stakeholder procurement approval. The company is JOSCAR accredited and holds ISO 9001, 14001, 45001, 27001, and Cyber Essentials Plus certifications, positioning it within vetted defence and government supply chains. Long-term anchor contracts such as the 15-year NL MOD support phase and 4+ year MPC Falklands engagement (230+ projects completed) provide multi-year revenue visibility well beyond initial delivery.

Broad incumbents

• AECOM: Global engineering and infrastructure services firm with defence and government clients requiring overseas facility design, construction and programme management — comparable engineering-delivery capability for complex and austere environments, though operating as a much larger diversified consultancy.
• QinetiQ: UK-listed defence technology and engineering group delivering test, evaluation and naval/maritime capability programmes to UK MOD — already a G3 customer (NavyPODS) and comparable UK defence engineering profile, though operating at substantially greater scale.
• Serco Group: Global public-services operator with significant UK MOD and FCDO contracts covering facilities management, emergency response and overseas infrastructure delivery — comparable customer segments and contract structures, with much larger scale and broader service portfolio.
• Babcock International Group: UK-listed defence and nuclear engineering services major with overlapping capability in defence infrastructure, through-life support and emergency response for UK MOD and allied governments — comparable customer base and contract types to G3, though operating at vastly greater scale and breadth.
• KBR Government Solutions: US-listed defence and government services contractor delivering deployable infrastructure, base operations support and logistics to US/UK/allied militaries — comparable deployable-infrastructure and through-life support offering, though focused on US DoD prime contracts at large scale.
• Thales UK: UK arm of global defence prime with capabilities spanning deployable communications, naval systems and secure infrastructure for UK MOD and NATO — comparable defence customer base and systems-integration approach, though at substantially larger scale and product breadth.

Direct peers

• Rubb Buildings: UK-based manufacturer of modular and containerised engineered structures for defence, aviation and industrial customers — directly comparable deployable-structure product category, though narrower in scope and lacking G3's full systems-integration depth.
• Cohort plc: UK-listed mid-market defence technology group supplying engineered systems and sub-systems to UK MOD and allied forces — directly comparable UK mid-market defence engineering profile, with similar dependency on government/defence customer mix and long-cycle contracts.
• Marshall Aerospace and Defence Group: UK-based defence engineering group delivering containerised and deployable systems, military vehicle conversions and through-life support to UK MOD and allied forces — closely comparable mid-sized UK defence engineering profile with similar deployable-infrastructure offering.
• Algeco: European modular and containerised building provider serving construction, infrastructure and defence customers with engineered portable buildings — directly comparable product category to G3's deployable containerised infrastructure, though with broader commercial-customer mix.
