Abstract
An apparatus for providing ignition of rocket motors by using sequenced iiation to an explosive logic network that is fail safe in case of accidental initiation. The explosive logic network has a multiplicity of input detonators for ignition of the explosive logic in a predetermined time program which must be accomplished in a specific ignition sequence to achieve a single explosive output to ignite the rocket motor squib and fire the motor. A deviation from the predetermined timed sequence or ignition of one or more of the input detonators will dud the system causing a fail safe condition of the logic network that prevents rocket motor ignition.
