An apparatus and process for generating a pulsed high-speed fluid jet that can be used to extinguish fires and/or to launch a projectile. A valve, such as an instant on-off valve, preferably operates in combination with a pressure accumulator. In a controlled manner, a pulsed fluid jet is generated and directed through a nozzle. The nozzle can draw into the fluid-jet an additive. The nozzle may also be used to launch a projectile using the fluid jet as a propellant.
