Goliath replica was build in 2011. We have 2D and 3D CAD documentation which was based on orginal Sd.Kfz.303 from WW2. Measurements of all parts, joinery technique as well as the built of all systems match the technology used in 1940.
Sd.Kfz.303 Goliath - whole vehicle
Complete vehicle equipped with original engine ZUNDAPP SZ7. Body and tracks are brand new replicas based on original Goliath from WW2. Ready to use. Various configuration options. There is option to use modern engine for example HONDA.
Sd.Kfz.303 Goliath - body replica
Complete brand new Goliath's body (main metal body, suspension, guage/beam wheels, driving wheels with cast cover, tracks stretching wheels, control panel etc.) ready to install original engine or modern engine and tracks. It contains more then 600 parts. Welding, riveting, benging etc. match the technology used in 1940.
Sd.Kfz.303 Goliath - tracks replica
Complete brand new set of tracks ready to be installed. It contains around 850 parts. Sheet metal parts welding and bending match the technology used in 1940.
Sd.Kfz.303 Goliath - original engine
Engine from WW2, 2 stroke, 2 cylinder, cooled by the air. It was taken from damage Goliath vehicle and use after WW2 as drive for 24V power generator. After full renovation (cylinder hole bushing and honing, new piston rings, planned head, perfect condition (carburettor, electromagnetic clutches work properly) ready to use.
Sd.Kfz.303 Goliath - modern engine
There is an option to purchase modern engine into Goliath's body. We have prepared a draft of the chain transmission system for modern engine. It includes also electromagnetic clutches. Vehicle with modern engine starts easier and is more controllable. Speed is the same.
The below presentation shows the stages of reconstruction GOLIATH vehicle. Photo report includes all activities occurring from the idea of reconstructing the vehicle until the first tests were held and the official presentation of the IV - The National Symposium on Historical Development of Construction Vehicles.
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.
