A post on a Russian Steampunk (Stimpank!) community offers a gallery of attractive images of N. Lebedenko’s amazing Netopyr, or Tsar Tank: a massive tricycle-like armored vehicle with a wheel span of 27 feet and cannons loaded on a rotating turret, the underbelly and the sponsons. The huge wheels were intended to roll over large ditches and walls, as well as gelatinize fleeing hordes of Bolsheviks. Unfortunately, they didn’t work very well, and the tank was abandoned where it was being tested, 60 kilometers from Moscow, for the next 8 years, until it was dismantled for scrap in 1923.
If The Empire Strikes Backhad played out not in science-fiction but Leninist folklore, the Tsar Tank would have been the AT-AT to Lenin’s Luke and Siberia’s Hoth.
