The Tsar Tank (Russian: Царь-танк, transcription: Tsar'-tank), also known as the Netopyr' (Russian: Нетопырь, which stands for Pipistrellus, a genus of bat) or Lebedenko Tank (Russian: танк Лебеденко), was a Russian armoured vehicle developed by Nikolai Lebedenko, Nikolay Yegorovich Zhukovsky, Boris Stechkin, and Alexander Mikulin from 1914 onwards. The project was cancelled in 1915 after initial tests deemed the vehicle to be underpowered and vulnerable to artillery fire.
