Abstract: A blast countermeasure for a vehicle, such as an armoured vehicle, is provided. The blast countermeasure comprises: at least one explosive; a detonator for detonating the explosive; and at least one reflector, located at least partially above the at least one explosive, for reflecting a shock wave generated by detonation of the at least one explosive groundwards in order to apply a groundwards force to the vehicle. The vehicle may comprise: control circuitry configured to respond to detection of an explosion local to the vehicle by activating an actuator to generate a groundwards force and cause a cabin floor of the vehicle to move groundwards.

Abstract: A vehicle, comprising: pressure detection means; vehicle stabilizing means; means for receiving an input from the pressure detection means, in response to the pressure detection means detecting an increase in pressure caused by an explosion; and control means for controlling, in response to reception of the input from the pressure detecting means, the vehicle stabilizing means to apply a force to the vehicle, in order to stabilize the vehicle in response to the explosion.
