The Landkreuzer P. 1500 Monster, possibly would have been the most astonishing tank if it ever made it into production.

  Now obviously the level of practicality is beyond low but hell this would be a real moral killer. Weighing in at 1,500 long tons and with a crew with over 100, nothing would have been able to compare to this giant. This would have used a 800 mm K (E) gun which would have fired that very large round you see in the picture. Along with that gun it would have also had 2x 15cm sFH 18/1 L/30 and multiple 15 mm MG151/15. The only thing to be able to power this beast would have been four MAN M9v 40/46 U-boat diesels with 2,200 hp.

   Well the reasoning behind why this did not even make it into the prototype stage is well beyond understandable. But if it did I think this would have been my favorite tank of all time.
