This self-explanatory “television controlled machine gun” appeared on the cover of the December 1944 issue of Radio Craft.  It was not, however, an existing weapon system.  Instead, it was the vision of publisher Hugo Gernsback, who wrote the accompanying article describing the system.

It was intended for a defensive position, and Gernsback admitted that it might eventually be overrun.  But when that happened, he noted, there would be no casualties.  And a second and third layer could then take over.

Gernsback also anticipated active night vision equipment.  He pointed out that his system could be used at night simply by installing some infrared floodlights, which the TV camera would pick up with no difficulty.
