Abstract: An existing, conventional fighter aircraft equipped with an air-to-ground weapons system is provided, through the present invention, with means for additionally carrying and releasing air-to-air missiles. A mounting member having a conventional air-to-air missile launcher attached to each side is provided with a pair of spaced lugs for engagement by the existing hooks on one or more of the aircraft pylons normally used for attachment of air-to-ground weapons. A pilot-controlled switch is selectively positioned to connect either the air-to-air or air-to-ground weapons systems with the existing weapons control network for operation upon actuation of the standard "fire", "uncage" or "reject" switches. Relay means associated with the launcher mounted member intitially connect a first of the two missiles carried thereby with the control network and, after actuation of either the fire or reject switch, automatically connect the second of the two missiles with such switches.
