Abstract
An anchoring system for anchoring a projectile launcher to the ground. The launcher includes a tubular body accommodating at least a projectile to be fired and a propellant charge. The system further includes least one anchoring element that penetrates the ground when the projectile is fired. The anchoring element can be moved between a first position in which it is at a distance from the ground and held by a body of the launcher by means of a temporary attachment device, and a second position in which it penetrates the ground. A control system causes the anchoring spike to move automatically from its first to its second position and is constituted by the pressure of the gases resulting from ignition of propellant charge.
