This little guy keeps coming back almost every museum I visit; the Goliath. Various version with differing means of propulsion have been produced throughout the Second World War. The main goal of this vehicle was to blow up the enemy. It essentially is a wire-guided bomb. An operator would steer it close to a nearby enemy vehicle via a remote control. Once it was in position, the explosive payload of the vehicle would be detonated and the enemy target destroyed.
Sd.Kfz. 302 (E-motor)
The original version of the Goliath, or Sonderkraftfahrzeug 302, saw service starting from April 1942. This model was powered by two electric motors. Due to the high production cost of the electric motor and the expendable nature of the vehicle this was considered to be rather wasteful. Until July of 1944 some 2650 specimens with electric drive where produced.
Both electric and petrol versions featured a similar design, which consists of a main body with three compartments. The front compartment contains an explosive charge. The middle compartment contains the motor and the last compartment contains a wire spool for the remote control.
Sd.Kfz. 303 (petrol drive)
A new variant was designed by Borgward which featured a petrol engine, officially designated Sd.Kfz. 303. Production began in April 1943. This version came into variants: a and b. The latter of which allowed a larger, 100 kg payload to be carried. The Sd.Kfz. 303 had a 703cc, two-cylinder motorcycle petrol engine by Zündapp. It has a distinctly different shape from its predecessor.
