A selectable force gas generator (SFGG) includes support material of honeycomb structure and a gas collection chamber contained in a housing. Gas-generating propellant cells are partially embedded in the support material. Each of the gas-generating propellant cells includes a steel jacket having a convex portion exposed to the gas collection chamber. The steel jacket has an orifice through the convex portion. Each propellant cell includes a propellant packet contained in the jacket. Each propellant cell includes a fire wire electrically connectable to an electrically-fired initiator and electrically connected to the propellant packet. The fire wire transmits a firing signal that causes the propellant packet to produce gas. A cap is positioned between the propellant packet and the jacket. The cap has a tip that blocks the orifice of the jacket and the thickness of the jacket is sufficient to prevent sympathetic detonation of the propellant packet.
