A depth control device for an underwater cable includes a rotary actuator having a rotating output shaft connected to a swash plate. Rotation of the swash plate by the actuator causes a rocker arm to pivot about an axis transverse to the axis of the output shaft. The rocker arm is drivingly connected to a drive shaft for rotating wings about their pitch axes. The pitch axes of the wings can be perpendicular to and intersecting the axis of the actuator output shaft, enabling the depth control device to be extremely compact.

[ What is claimed is:] [14.] A depth control device for an underwater cable comprising:a hollow body for attachment to an underwater cable;a drive shaft having a rotational axis and extending to an exterior of the body through openings in the body;first and second wings disposed outside the body on opposite sides thereof and mounted on the drive shaft for rotation therewith; andan actuator assembly disposed in the body and engaging the drive shaft to rotate the drive shaft about the rotational axis of the drive shaft, the drive shaft being disengageable from the actuator assembly and removable from the body through one of the openings in the body.
