Overall view of one of the carbon jet vanes.
The jet vanes (which extended into the engine exhaust), in conjunction with the
air rudders, were used to control the
missile's attitude. During the early portion of the missile's flight, it was
controlled by the jet vanes. When the missile reached a velocity sufficient
for it to become aerodynamically stable, the air rudders took over the control
The carbon vanes and air rudders were driven by the same actuator
assembly and turned simultaneously.
