 The Germans developed an electrical two-axis joystick around 1944.The device was used as part of the Germans' "Funkgerät" FuG 203 "Kehl" radio control transmitter system used in certain German bomber aircraft, used to guide both the rocket-boosted anti-ship missile "Henschel Hs 293", and the unpowered pioneering precision-guided munition "Fritz-X", against maritime and other targets.Here, the joystick of the "Kehl" transmitter was used by an operator to steer the missile towards its target.
