Abstract

Mortar ammunition with a projectile body and a tail tube containing the necessary propellant charge. The tail tube and the projectile body constitute two separate components which, for the purpose of being loaded into the mortar, are capable of being lowered in turn into the mortar via its barrel until they come into contact with each other inside the barrel. When the mortar is fired the projectile body will leave the mortar without taking with it the tail tube. The projectile body and the tail tube make contact with each other via a girdle fixed to the tail tube, said girdle being caused by the gases from the propellant charge to become detached from the tail tube and to become securely attached to the projectile body, so that the girdle is carried out of the barrel by the projectile body.
