Approximately 25 high-time Fortresses (mainly B-17Fs) were converted into radio-controlled flying bombs under the designation BQ-7. They were designed to be used against German V-1 missile sites, submarine pens or deep fortifications that had resisted conventional bombing.
The name of the USAAF officer who first thought of the idea of using war-weary B-17s as flying bombs has been lost to history, but the plan was proposed to Maj. Gen. James Doolittle under the code name Operation Aphrodite, and he approved it on June 26, 1944.
Responsibility for preparing and flying the drone aircraft was given to the 3rd Bombardment Division, which passed the job down to the 388th Bombardment Group, which in turn passed responsibility down to the 562nd Squadron based at Honington in Suffolk.
The B-17s selected for the project were stripped of their normal military equipment and packed with up to 9 tons of explosives. Each pilotless bomber was fitted with a radio-controlled flight system known as Double-Azon and a television camera was placed on the flight deck so that an image of the main instrument panel could be sent back to a controlling aircraft.
A second TV camera was installed inside the Plexiglas nose which gave a television monitor in the controlling aircraft a view of the ground so that the robot machine could be directed onto the target.
Azon was originally for radio-controlled bombs:
Each aircraft had three antennas mounted beneath its tail section for control purposes. One transmitted a signal on 475 cycles for left deflection, one on 3,000 cycles for right deflection, and the third at 30-40 cycles to activate the smoke generating system. All three frequencies were changed periodically to prevent jamming by enemy radio monitoring crews.
The transmitter was a standard Signal Corps type used in controlling model planes, ships, tanks, and drones. With a power output of 25-watts, the unit was capable of sending on 15 different frequencies. This equipment weighed 33 pounds, and modification to the B-24, for accommodating it, amounted to an additional 25 pounds.
Dont have any stuff on the 1950's control, but it woulda have to be advanced from this.
