Abstract : A lateral force device for displacing a towed underwater acoustic cable providing displacement in the horizontal and vertical directions having a spool and a rotationally mounted winged fuselage. The hollow spool is mounted on a cable with cable elements passing therethrough. The winged fuselage is made with the top half relatively positively buoyant and the bottom half relatively negatively buoyant. The winged fuselage is mounted about the hollow spool with clearance to allow rotation of the fuselage. The difference in buoyancy between the upper and lower fuselage maintains the device in the correct operating position. The wings are angled to provide lift in the desired direction as the fuselage is towed through the water.
