That is one badass gun tho, the shell is taller than a human being.
There’s also the V3, another large nazi cannon. While the bore was ‘only’ 15cm/6in it was 150m long, compared to the 36m of dora. It was designed to fire on london from it’s position deep in a bunker in france.

Well , dont know about anyone else but I’m still hugely disappointed that there is no such thing as a giant robotic russian gun patrolling its borders. curse you photoshop for your oh so realistic imaging trickery!!!
At 1972 I seen and touched brass Dora shells on one of Soviet weapen ammunition depot in Germany Democratishe Republik. It served as fire-vat with water near the hangar doors.
