Soviet concept tank from the early 1980s - was developed to the point of a scale mock-up, but no further. Part of the concept was a highly unconventional layout, with the turret ring built into the sloped frontal armor, which gave the tank a lower profile and better frontal protection, but also limited its ability to aim at things behind it (because the hull would be in the way, the gun couldn't depress below about +20 degrees). There's an Imgur gallery with a set of design sketches, images of the mock-up, and pictures of a CG model: https://imgur.com/gallery/sd5aMKp Additionally, back in April 2015, user TypicalRussianIvan posted a few pictures of a different CG model to this group: https://www.moddb.com/groups/tanks/images/soviet-prototype-from-1980s#imagebox - user Watchdream posted a link to a Russian article on the design: http://btvt.narod.ru/raznoe/vbtt_1991_komponovka.htm ; Google translate of the page: https://translate.google.com/translate?hl=en&tab=wT1&sl=auto&tl=en&u=http://btvt.narod.ru/raznoe/vbtt_1991_komponovka.htm
