A countermass for recoilless weapons which is intended to be placed behind the projectile propelling charge (3) of the weapon and which is also intended to depart together with the propellant gases exiting rearwardly from the weapon when the projectile is propelled forwards. The countermass includes a countermass body (5) which is deformable at the pressure and the temperature prevailing in the barrel during firing of the projectile and which has at least one gas throughflow passage (6) which widens rearwardly in nozzle form. |
