MOSCOW, Aug 10. The American publication The National Interest has named the T-90S tank one of the most successful developments in the Russian military industry for export. According to the author of the article, Mark Episkopos, many changes have taken place since the T-90 was commissioned. Initially, the tank was an improved version of the T-72: a vehicle weighing 48 tons developed a speed of up to 60 kilometers per hour and covered 550 kilometers without additional refueling. National Interest called the Russian T-90M tank a «monster» As a result, the T-90S combined all the positive qualities of previous models, such as the T-64, T-72 and T-80. The journalist considered its key characteristic to be a combined armor consisting of a composite alloy. The vehicle also has a Kontakt-5 dynamic protection system and a Shtora-1 optical-electronic countermeasure system. Other advantages include the upgraded 2A46M smoothbore cannon and remotely controlled and twin machine gun mounts. The T-90 is a Russian main battle tank developed by Uralvagonzavod in the early 1990s. From 2001 to 2010, it was the best-selling in the world market.
