Russia is planning a tethered mother drone carrying up to six wired mini spy UAVs

Russian spy drones.

• Russia patented a carrier drone capable of deploying six tethered reconnaissance copters
• One airborne platform controls multiple surveillance drones through physical cable connections simultaneously
• Each tethered copter receives power and commands directly from the carrier aircraft

A newly-patented Russian drone design turns a single aircraft into a mobile hub for up to six smaller spy copters.
