Abstract: A rocket retention and ignition system including in one embodiment, a linearly movable rocket retaining and firing pin biased by a spring to an extended position within the launch cavity of a rocket launcher tube. An electrically actuable solenoid, upon the application of an actuating signal pulls the pin to a withdrawn position so that its retaining end is flush with the inside wall of the launcher tube. A firing contact on the pin, designed to mate with a similar firing contact within the rocket, conducts a firing signal for igniting the rocket. An electronic control system generates a firing signal on a line electrically coupled to the pin firing contact and a solenoid actuating signal coupled to the solenoid with appropriate timing so that the firing signal is applied followed after a predetermined interval of time by the solenoid signal. In another embodiment, there are provided separate firing and retaining pins.
