Vehicle armour comprising an assembly of: A an outer armour pack comprising: i) an outermost outer fibre reinforced composite protective layer of at least 1mm thickness; ii) an outer ceramic armour layer to protect against small arms and provide initial fragmentation of a penetrator; and iii) an inner fibre reinforced composite support layer to absorb residual energy from small arms; the outermost outer fibre reinforced composite protective layer being configured to protect the outer ceramic armour layer against minor impacts; B an air gap of between 1mm and 10mm to allow for deflection of the outer armour pack; C an inner armour pack comprising: i) an outer fibre reinforced composite protective layer of at least 0.5mm thickness; ii) an inner segmented ceramic armour layer configured to provide the majority of protection against a penetrator; iii) an innermost inner fibre reinforced composite layer of at least 10mm thickness; the outer fibre reinforced composite protective layer being configured to protect the inner segmented ceramic armour layer against damage during handling or maintenance of the armour; D a high energy absorbing layer of at least 25mm thickness configured to mitigate the effect of residual fragments defeating the outer and inner armour packs; the assembly being configured to be mounted in spaced relationship to the hull of a vehicle.
