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 miles per hour (9.7 km/h)), poor ground clearance (just 11.4 centimetres), 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.[5] Mostly, they failed to reach their target although the effect was considerable when they did.[5]
