Goliath tracked mine

Goliath tracked mine is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Goliath tracked mine rather than just read about it. In short: The Goliath tracked mine (German: Leichter Ladungsträger Goliath, "Goliath Light Charge Carrier") was a series of two unmanned ground vehicles used by the German Army as disposable demolition vehicles during World War II. These were the electrically powered Sd.Kfz. 302 and the petrol-engine powered Sd.Kfz. 303a and 303b.

Key takeaways

  • Goliath tracked mine belongs to engineering; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Goliath tracked mine to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Goliath tracked mine from memory before moving on to harder problems.

Reference excerpt

The Goliath tracked mine (German: Leichter Ladungsträger Goliath, "Goliath Light Charge Carrier") was a series of two unmanned ground vehicles used by the German Army as disposable demolition vehicles during World War II. These were the electrically powered Sd.Kfz. 302 and the petrol-engine powered Sd.Kfz. 303a and 303b. They were known as "beetle tanks" by the Allies. They carried 60 or 100 kg (130 or 220 lb) of high explosives, depending on the model, and were intended to be used for multiple purposes, such as destroying tanks, disrupting dense infantry formations, and the demolition of buildings or bridges. Goliaths were single-use vehicles that were destroyed by the detonation of their warhead.

Development During and after World War I, a number of inventors devised small, remote-controlled, tracked vehicles intended to carry an explosive charge. During the war, the French developed two vehicles. The Crocodile Schneider Torpille Terrestre (transl. 'Land Torpedo Crocodile Schneider') carried a 40 kg (88 lb) explosive charge and saw limited combat use in June 1916. However, it performed poorly and was eclipsed by the first tanks, then being introduced. The Aubriot-Gabet Torpille Électrique (transl. 'Aubriot-Gabet Electric Torpedo') was driven by a single electric motor powered by a trailing cable. This vehicle may have been steered by clutch control on its tracks, although early versions may have lacked steering. This may not have mattered as its task was simply to cross no man's land to attack the long trenches of the enemy. The Wickersham Land Torpedo was patented by American inventor Elmer Wickersham in 1918 and in the 1930s, a similar vehicle was developed by the French vehicle designer Adolphe Kégresse. In late 1940, Kégresse's prototype was recovered by the Germans near the Seine; the Wehrmacht's ordnance office directed the Carl F.W. Borgward automotive company of Bremen, Germany to develop a similar vehicle for the purpose of carrying a minimum of 50 kg (110 lb) of explosives. The result was the SdKfz. 302 (Sonderkraftfahrzeug, transl. 'special-purpose vehicle'), called the Leichter Ladungsträger (transl. 'light charge carrier'), or Goliath, which carried 60 kg (130 lb) of explosives. The vehicle was steered remotely via a joystick control box. The control box was connected to the Goliath by a 650-metre (2,130 ft), triple-strand cable. The cable was stored on a cable drum in the rear compartment of the Goliath. The cable was used for steering the vehicle left/right, forwards and reverse (reverse on the electric driven 302 version only) and to ignite the explosive charge. Each Goliath was disposable, being intended to be blown up with its target. Early model Goliaths used two electric motors but, as these were costly to make (3,000 Reichsmarks) and difficult to maintain and recharge in a combat environment, later models (known as the SdKfz. 303) used a cheaper two-stroke petrol engine.

Service

Goliaths were used on all fronts where the Wehrmacht fought, beginning in early 1942. They were used principally by specialized Panzer and combat engineer units. Goliaths were used in Italy at Anzio in April 1944, and against the Polish resistance during the Warsaw Uprising in 1944. A few Goliaths were also seen on the beaches of Normandy during D-Day, though most were rendered inoperative after artillery blasts severed their command cables. Allied troops encountered a small number of Goliaths in the Maritime Alps following the landings in southern France in August 1944, with at least one being used successfully against a vehicle of the 509th Parachute Infantry Battalion. Although a total of 7,564 Goliaths were produced, the single-use weapon was not considered a success due to high unit cost, low speed (just above 6 kilometres per hour (3.7 mph)), poor ground clearance (just 11.4 cm (4.5 in)), the vulnerable control cable, and thin armour which could not protect the vehicle from small-arms fire. The Goliath was also too big and heavy to be easily man-portable. They mostly failed to reach their targets, although the effect was considerable when they did. Large numbers of Goliaths were captured by the Allies. Although they were examined with interest by Allied intelligence, they were seen as having little military value. Some were used by the United States Army Air Force as aircraft tugs, although they quickly broke down as the disposable vehicles were not designed for sustained use.

Romanian version In the years leading up to the Second World War, Romania designed and built its own model of remote-controlled tracked mine, commonly known as "Romanian Goliath", but officially designated "Torpila terestră dirijată Eremia" ("Eremia guided land torpedo"). It was markedly different from its later German counterpart. The few surviving photos show that the vehicle, unlike the German Goliath, had no armour at all, and it is not known if that was ever changed. The Romanian-designed chassis allowed it to cross trenches and craters much better than its German counterpart. Little more is known about the vehicle, other than that it never went beyond the prototype stage and that it weighed about two tonnes.

Worked examples

Example 1 — a first encounter with Goliath tracked mine

Start with the simplest possible case. Write down what Goliath tracked mine claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Goliath tracked mine before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Goliath tracked mine ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Goliath tracked mine

In research
Goliath tracked mine appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Goliath tracked mine in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Goliath tracked mine is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1940s robots, Explosive weapons, Military robots, so understanding it makes those chapters shorter.
In everyday life
Look for Goliath tracked mine outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
