Abstract: A base of a TOW missile system is mounted on a rotatable turret of a vehicle and is also rotatably mounted relative to the rotation of the turret so that the orientation of the base about its own rotational axis remains stationary. The positioning of the TOW base on the turret allows the turret to rotate generally about an axis which can be aligned with the person operating the sight. Thus the diameter of the opening in the vehicle is reduced. One embodiment uses a planetary gear system for holding the orientation of the base. A second embodiment uses a flexible link.
