A fluid jet apparatus includes a housing defining a propellant cavity, a fluid cavity, and a passage through the housing in fluid communication with the fluid cavity. The apparatus further includes a membrane separating the propellant cavity and the fluid cavity, a propellant disposed in the propellant cavity, and a fluid retained in the fluid cavity. The propellant urges the fluid from the fluid cavity through the passage upon initiation of the propellant. A munition system includes a munition and at least one fluid jet apparatus adapted to vent the munition. A method includes initiating a propellant to produce a rapidly expanding gas and urging a fluid through a passageway with the gas to produce a fluid jet.
