The "Armata" Universal Combat Platform () is a Russian advanced next generation modular heavy military tracked vehicle platform. The Armata platform is the basis of the T-14 (a main battle tank), the T-15 (a heavy infantry fighting vehicle), a combat engineering vehicle, an armoured recovery vehicle, a heavy armoured personnel carrier, a tank support combat vehicle, and several types of self-propelled artillery, including the 2S35 Koalitsiya-SV under the same codename based on the same chassis. It is also intended to serve as the basis for artillery, air defense, and NBC defense systems. The new "Armata" tank platform is meant to replace the older Russian main battle tanks and APCs that are currently used by the Russian military. Origin of designation The combat platform is formally designated as "prospective family of heavy unified battlefield platforms". The name "Armata" derives from the plural of the Latin word which refers to weapons of war, and was an old Russian word for 14th century guns; it is also the plural of the ancient Greek word "Arma", meaning "chariot" or in modern Greek, "tank". This was wrongly transcribed as "Armada" by journalists on several occasions. Development The Armata combat platform has been under design and development since 2009 by Uralvagonzavod headquartered in Nizhny Tagil. Prototypes of heavy armored vehicles based on the Armata combat platform were presented at the defense exhibition Russian Arms Expo in Nizhny Tagil in September 2013. In November 2014 trials of the 2S35 Koalitsiya-SV self-propelled gun variant were under way. The first vehicles were shown to the public in the 2015 Moscow Victory Day Parade, with a batch of 32 to be delivered to the Russian Land Forces during the same year. Russian media has previously stated that mass delivery will start in 2015 or 2016. A total of 2,300 MBTs were expected to be supplied by 2020, modernizing 70 percent of the Russian tank fleet. The Uralvagonzavod plant was expected to roll out around 500 T-14 Armata tanks per year. In 2017, the order was scaled back to a test batch of 100 tanks by 2020, with the program extended to 2025. At a 2015 Moscow Victory Day Parade practice drill run on the Alabino training grounds several types of armored vehicles described as various Armata models appeared with their turrets covered. Russian Defence Ministry signed a long-term contract for delivery of tanks and heavy IFVs on the Armata basis.
