A blast dissipation device for an armored vehicle includes a first absorption system and a second absorption system that are usable to dissipate initial blast forces exerted upon an underbelly of the vehicle caused by, for example, detonation of an IED below the vehicle. The second absorption system has a delayed reaction to forces exerted upon the underbelly of the vehicle. The first absorption system reacts more quickly and serves to dissipate initial forces until the second absorption system is activated to dissipate the remaining forces.
