Russian Czar tanks

Eräs suunnitelma panssarivaunun valmistamiseen oli tsaarin venäjän merivoimien insinöörin V D Mendelejev 1911 ajatus. 
Vaunu ehti vain suunnitelu pöydälle, ei kauemmas. 
                              

Vaunun aseistuksena oli StShamond tankin tapaan, keskellä rungon edessä edessä yksi 120mm tykki, tankin päällä pyörivä torni, jossa oli yksi konekivääri. 
Vaunun 1000 hv / 735 kw moottori oli sukellusveneestä jotka myös vielä tuohon aikaan olivat monet uutuus keksintöjä, Mendelejev tankin paino oli noin 173.000 kg.

The first super-heavy tank was designed by the Russian naval engineer Vasily Mendeleyev who worked on the project from 1911 to 1915. 

The tank was envisioned to be invulnerable to almost all contemporary threats but remained on paper because of its high construction cost.
Two of them were under construction when the war ended and both were demolished.

                              

Venäjä kehitti ja kokeili monia panssarivaunumalleja tsaarin aikana 1914-1918, mutta ne eivät edenneet tuotantoon asti.
                              
Maastokelpoinen ajoneuvo, Vedsjeshod, esiteltiin 1915 ensikertaa koe tyyppi vaunu.
Takana oli yksi leveä telaketju ja edessä kaksi pyörää joilla vaunua voitiin ohjata.
Vaunusta tehtiin parannettu malli, mutta se ei edennyt piirustuspöytää pidemmälle.

The Vezdekhod had a welded frame which ran on a wide single track made from rubberized fabric stretched over four drums, with a fifth drum tensioning the track from above. Two small wheels were placed on the sides of the track, and could be lowered to steer it, being controlled by a steering wheel. 

The machine was propelled by a 10 hp petrol engine driving through the rear drum. Porokhovščikov intended that the Vezdekhod should run on the back drum and its wheels while on firm ground, while on soft ground it would lie down on its track. Preliminary automotive testing began on 18 March.
                             
Technical drawing of a Vezdekhod tank.
Construction of the prototype began in February 1915 with the first tests on a paved road being carried out in May, with further tests proceeding until the end of the year. 

In cross-country trials the Vezdekhod was reported to be capable of a speed of 40 Verst per hour (26.5 mph) with simulated armor weight but proved impossible to steer using the wheels provided for that purpose and the project was therefore rejected, the Military Technical Department forbidding further work on it after December 1915.
