This replica was built several years ago, constructed by Allan Swatman and Dave Marson, built from steel (its as heavy as the original ! ), it operates via radio control, which drives the two 12v electric motors, through a reduction gear box to the tracks. The radio control can also operate pyro charges or smoke to simulate an explosion.
The Original Goliath:
Originally Manufactured by Carl F.W. Borgwards automotive company of Bremen. Called the Leichte Ladungsträger ‘light demolitions carrier’ or Goliath, which carried 60kg of explosives. The vehicle was steered remotely via a control box to trailing wires The hull contains three sections, front: high explosives, middle: control and power unit, rear: control cable and drum, Powered by a large capacity battery, power was transferred via two electric motors to a chain drive, cutting power to one side would brake and turn the tank. Controlled via 3×2 pair trailing cables , two for turning left or right, the third used to detonate the 100-125lb of explosives.
Early model Goliaths used an expensive electric motor (300 reichmarks) and were difficult to repair in a combat environment, the later SdKfz. 303 used a simpler, more reliable petrol engine. Goliaths were used on all fronts where the Wehrmacht fought, beginning in spring 1942. They were used principally by specialized Panzer and Combat Engineers units. Goliaths were used most notoriously in the Warsaw uprising of 1944, as Wehrmacht and SS units were deployed to crush fierce Polish resistance by the Polish Home Army. Volunteers were often sent to cut off the command cables of the Goliath before it reached its intended target. A few Goliaths were also seen on the beaches of Normandy during D-Day, though most were rendered inoperative due to artillery blasts severing their command cables.
Although a total of 7,564 Goliaths of both models were produced, the single use weapon was not regarded as being successful because of its high unit cost, slow speed (only just above 6mph, or 9.5kph), poor ground clearance, thin armour that did not protect it from any kind of modern antitank weapons and vulnerable command cables. In use the Goliath command cables could be easily cut by a single combatant with a shovel. The Goliath helped lay the foundation for advances in remote-controlled vehicle technologies.
