The loading operation of the huge shells was also interesting, for it must be remembered that some of the missiles weigh nearly a ton. After the tremendous rebound of the gun, the breech block was opened, the opening mechanism being so arranged that the cartridge shell would be extracted automatically, thus preparing the gun for the next shell.
