Video of a Sdkfz 302 Goliath explosive carrier/tracked mine being used on an SU-85 tank destroyer.

Early models were propelled by two small electric motors, and could achieve a top speed 6 miles per hour. Later models (the 303 variants) utilized a small diesel motor, because the electric ones were more expensive to manufacture.

Goliaths could carry between 130-220 pounds of explosives, and were often employed in destruction of enemy tanks, or clearing lanes in minefields.

They had a command wire that was about 2100 feet long, and were controlled by a small joystick.

Because of their high unit cost, lack of protection against small arms fire and anti tank weapons, poor ground clearance, and because of the fact their command cable could easily be severed by shrapnel, they weren’t that successful. Despite this, Goliaths, and their larger cousins the Borgward remote control explosive carrier laid the foundation for remote control technology after the war was over.

Around 7500 units were produced by war’s end.
