An igniter for high-performance rocket motors having a full, head-end web of propellant in the forward end of the motor comprises a closed, rigid pressure vessel having walls which are formed of a consumable filament structure. The igniter includes a hollow cylindrical solid propellant having a high surface grain area which operates at high pressure and is removably attached to a liner that is provided in a cavity in the aft end of the propellant. The liner is machinable with the motor propellant grain thereby facilitating propellant grain cutback if required by a change in mission of the motor. The thrust produced by the igniter neither applies stresses to the motor propellant nor exerts any forces tending to eject it from the cavity.
