Britain entered the First World War, having a very small number of heavy guns, so one of its main concerns was to establish the production of such equipment. Since the equipment for the production of 203-mm (8-inch) guns abounded, managed to establish their production rather quickly, while the model was developed and carriages for them. Cannon got heavy, with riveted iron rectangular platens and large wheels. Since the system was imperfect rollback, behind the wheels had to lay a heavy shoes. The management of fire cannon threw back strongly, and these shoes, taking over most of the recoil energy, heavily buried in the ground. If they were installed sloppy, then the rebound gun sometimes could roll over them.
Heavy howitzer Mark 7 was introduced in 1916 and represented a new and improved design of the gun, it had a larger range and equipped with more effective recoil device. However, the shoes under the wheels had to be installed in the same way as before. During the Second World War, many howitzers of this type were converted into 182.9-mm (7.2-inch) guns by replacing liners.
