that this would not be a whopper cannon at all. Even if we assume that the barrel would fire grapeshot, a massive amount of propellant would be needed to push the two-ton shot, making it impossible for the cannon to be transported from one position to another. Therefore Chokhov did not mean to cast it as a functional cannon at all. His cannon is always only a symbol of Russian power and of the capabilities of the Russian industry. If we render a Russian master able to create such a whopper cannon, the smaller ones would have much less use. Therefore, the Tsar Cannon was put on display in the Kremlin for foreign diplomats." The cannon was last restored in 1980 in the town of Serpukhov. It was thoroughly studied by specialists in the Artillery Academy at that time and gunpowder residue was found, indicating that the cannon had been fired at least once, hinged and dug into the ground.

Replicas The Donetsk copy In the spring of 2001, as commissioned by the management of the Moscow Udmort enterprise "OAO Izhstal", a replica of the cannon was cast in iron. The replica weighed 42 tons, with a single wheel at 1.5 tons, the kernel at 1.2 meters and a caliber of exactly 89 cm. This copy was given as a present from Moscow to Donetsk, which was installed in front of the Donetsk City Hall in May 2001. There were two copies, with the other one produced in Izhevsk set in the premises of OAO Izhstal. The Yoshkar-Ola copy In 2007, another replica was installed in front of the National Art Gallery in Yoshkar-Ola. This replica was made in a scale of 1:2. This replica is incomplete, with ornaments changed or absent, and other details missing. The kernel of the cannon weighs about 12 tons, with the barrel and the carriage cast in steel, and the wheels being solid. Three staples were installed on the cannon for fastening cables when moving it. It was cast on Zvenigovsky Shipyard named after N. S. Butyakov. Initially, the ornaments were cut from wood, and then cast from metal. The copy was suitable for shooting, as the
