The artillery pieces appeared to be patterned after the famous 280mm (eleven inch in caliber- on the nose!) Railroad guns popularily called Big Berthas. These were made by Krupp and had an accurate tactical range of over 2l miles- and inaccurate plunging fire far beyond that. That is why they used Radar fire-control in the film. The Big Berthas were used in both RR and in this case turret mounts, in both World Wars.
