This invention relates to a missile launcher and more
slidably mounted the missile sled 20.
Base 5 is rotatable
in a horizontal plane in known manner on an unshown
support in order to aim the missile in the desired direction
and guide member 8 is pivotable in a vertical plane to
provide the proper launching inclination for the intended
trajectory for a given missile and a given target.
The means to pivot the guide member 8 comprises a
frame 16 and hydraulically operated pistons 11. The

The arcuate
upper edges of these brackets have one or more arcuate
rows of spherical sockets rotatably seating precision balls

Only the outer portions of these balls are exposed
beyond the edges of their respective seating sockets and
these engage and support the exterior of cylindrical sur

well as during its launching. If desired, the opposite
ends of the bearing provided by balls 42 have pivoted
