A mechanism mounted on a missile launch rail which may be actuated to perform the functions of engaging electrical circuit firing contacts for the missile, rotating a rocket motor arming arm, and unlocking the forward motion missile restraints. Particular structure including a bi-directional linear actuator drive mechanism is provided to perform these functions. In addition, the structure incorporates the capabilities of restraining the rocket motor against full thrust in the event of an inadvertent firing and of restoring the rocket motor to safe condition if a launch is aborted.

A bi-directional linear actuator arming device for use with a rocket missile launcher having a guide rail for engaging support members on the missile comprising: a housing mounted on the guide rail and supporting rotatable restraining means extending through openings in the guide rail to engage port

A bi-directional linear actuator arming device for use with a rocket missile launcher having a guide rail for engaging support members on the missile comprising: a housing mounted on the guide rail and supporting rotatable restraining means extending through openings in the guide rail to engage portions of the missile; a selectively reversible motor having a shaft rotatable in either direction; a linear traversal shuttle member movable along the guide rail between an extended position of engagement with the restraining means and a retracted position out of engagement with the restraining means; means coupled between the motor shaft and the shuttle member for converting rotational movement of the motor shaft to linear traversal movement of the shuttle member between the extended and retracted positions; and means coupled to the shuttle member and movable therewith for changing the condition of the missile between safe and armed conditions when the shuttle member moves between the extended and retracted positions.
