The electrical two-axis joystick was invented by C. B. Mirick at the United States Naval Research Laboratory (NRL) and patented in 1926 (U.S. Patent no. 1,597,416)".  NRL was actively developing remote controlled aircraft at the time and the joystick was possibly used to support this effort.  In the awarded patent, Mirick writes: "My control system is particularly applicable in maneuvering aircraft without a pilot."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. This joystick had on-off switches rather than analogue sensors. Both the Hs 293 and Fritz-X used FuG 230 Straßburg radio receivers in them to send the Kehl's control signals to the ordnance's control surfaces.  A comparable  joystick unit was used for the contemporary American Azon steerable munition, strictly to laterally steer the munition in the yaw axis only.This German invention was picked up by someone in the team of scientists assembled at the Heeresversuchsanstalt in Peenemünde. Here a part of the team on the German rocket program was developing the Wasserfall missile, a variant of the V-2 rocket, the first ground-to-air missile. The Wasserfall steering equipment converted the electrical signal to radio signals and transmitted these to the missile.
