An apparatus for controlling the propulsion and direction of an air cushion vehicle including a housing and a first vane pivotally coupled to the housing and pivotable about a first axis. A second vane assembly including at least one second vane is disposed within the first vane. The second vane assembly is pivotally coupled to the first vane and pivotal about a second axis. The second axis is orthogonal to the first axis. A first actuator is operably coupled to the first vane and a second actuator is operably coupled to the second vane assembly. The first actuator pivots the first vane and the second vane assembly about the first axis. The second actuator pivots the second vane assembly relative to the first vane and about the second axis to control the flow of air through the housing.
