There is disclosed a fire suppression mechanism for a military tracked vehicle. The mechanism includes a number of relatively small cylindrical pressure vessels, each having a floating piston that separates the respective cylinder into 2 chambers. Vaporizable liquid fire suppressant material (such as C Br F3) occupies one chamber; an inert pressurized gas such as nitrogen occupies the other chamber. An electrically-controlled valve at one end of each cylinder can be remotely triggered open to enable fire suppressant vapor to be discharged from the cylinder under the driving force provided by the pressure of the inert gas; the floating piston shifts along the cylinder as the vapor is discharged from the cylinder toward the developing fireball within the vehicle. Each cylinder is oriented in a horizontal prone position at a central point in the vehicle.

In a tracked military vehicle comprising a hull subdivided into a rear engine compartment and a forward driver compartment, a turret rotatably mounted on a central portion of the hull upper wall and having a basket depending therefrom into the hull interior space, the hull having a bottom wall spaced below the basket to define an intervening clearance space; the improvement comprising fire suppressant means disposed in the aforementioned clearance space, said fire suppressant means comprising first horizontally-oriented cylinder means underlying the rear portion of the basket and second horizontal cylinder means underlying the front portion of the basket, each said cylinder means comprising a cylindrical pressure vessel having end walls and an intermediate floating piston, a flashable vapor fire suppressant material changed into the space between one end wall and the piston, an inert pressurized gas charged into the space between the other end wall and said piston, an electrically-operated valve mounted on said one end wall of each pressure vessel to control the escape of pressurized suppressant from the vessel; the cylinder means being oriented so that the first cylinder means discharges suppressant to the engine compartment and the second cylinder means discharges suppressant to the driver compartment.
