Dora Gun

The super heavy siege gun, Dora. the Germans built two of these monsters: the Schwerer Gustav, and Dora. the gun was able to fire from Germany into France. it weighed in at around 1330 tonnes and each shell weighed 7 tonnes. it requiered a crew of 250 and there was a 30-45 minute gap to reload. its barrel was 30 meters long. and it was capable of firing a 1 meter shell! the barrel as an 80 cm barrel.

It was designed to punch through French forts renforced with 7 feet of steel and concrete; and it worked with great success.

The Allies captured one of them and the Germans destroyed the other for fear of the Red Army gaining control of it. I dont blame them.
