Project implementation

   Works under the imperial patronage went quickly - was soon made in the metal and the late spring of 1915 met secretly in a forest of Dmitrov. August 27, 1915 was made the first sea trials of finished cars. The use of larger wheels require the off-road device, which was confirmed in the tests - the machine broke birch as matches. However, the rear driven roller, due to their small size and inappropriate distribution of weight machines in general, almost immediately after the commencement of testing of stuck in soft ground. Big wheels have been unable to pull it, even using powerful for those times propulsion system consisting of two motors trophy "Maybach" of 240 liters. with. each (much more powerful than used in the other tanks of the World War), taken with the hit German airship. Also, the test revealed later seemed the obvious vulnerability of large vehicles - mainly wheel - with the shelling, especially high-explosive shells. All this has led to what is already in August, has been minimized as a result of the negative opinion of the High Commission, however, and Zhukovsky Stechkin still engaged in the development of new engines for cars. However, this attempt failed as well as attempts to move the king-tank from the floor and pull it out of the test area.

   Until 1917, the tank was under the protection of on-site testing, but then because of the outbreak of the political upheavals of the car is forgotten and no longer remembered. Design work on it no longer held, and a great surrealist structure built vehicle with 7 years became rusty in the woods, on-site testing, while in 1923 the tank was dismantled for scrap metal.
