Cutting edge technology

Crewshield Armoured Citadels are designed to keep your personnel safe from external threats for extended periods through a range of anti-assault features and independent support systems which include: armoured protection, electrical power, air, water, sanitation and external communications. Our patented 20’ high capacity, high endurance citadel variant is BR6+ armoured as standard and comes with a range of communication options within our patented modular design, enabling us to build to bespoke client requirements. Capable of immediate operation in temperatures as high as 55°C, each unit has capacity for 24 persons and up to 96 hours completely independent operation after the loss of external power.

Discreet for sensitive environments

The external appearance of a shipping container disguises the true function of every citadel. Ideal for environments where situations can develop rapidly but a low profile presence is required, from exploration units to development agencies, our market leading system is deployed in 3 continents and is Patent protected in over 40 countries.
