Oplot-M Tank - Ukraine:
The Oplot-M main battle tank (MBT) is developed by Kharkiv Morozov Machine Building Design Bureau (KMDB) for the Ukrainian Armed Forces. The MBT can destroy ground-based and low-flying, low-speed aerial targets, while offering superior protection and high mobility for troops. The Ukrainian Ministry of Defence inducted the Oplot-M MBTs into service in 2009. In September 2011, the Royal Thai Army placed an order with Ukrainian arms trading company Ukrspetzexport for 49 Oplot MBTs. The Oplot-M (Modernised) or BM Oplot is an upgraded version of the T-84 Oplot MBT. The tank has a conventional layout with the driver's compartment at the front, fighting compartment in the middle and engine at the rear, accommodating a crew of three members.
The T-84 is the latest Ukrainian development of the T-80 series, designed by KMDB in Kharkiv. A main design objective was to make Ukraine's arms industry independent of Russia's, after resulting difficulties in fulfilling a contract to supply T-80UD tanks to Pakistan. An external difference from earlier models is the new Ukrainian welded turret, replacing the T-80's Russian-built cast turret (some T-80s shipped to Pakistan were fitted with the T-84 welded turret, but lack other T-84 improvements).
The T-84's outstanding feature is the 26 hp/t power-to-weight ratio. It has inherited the nickname Flying Tank from the T-80. The tank is also designed to perform well in hot climates, and even includes an air-conditioned crew compartment (operating temperature range is claimed to be −40 °C to 55 °C).
Due to the collapse of Soviet Union, the Malyshev Factory was no longer able to obtain ceramic armour modules from Russia and only the initial batch of T-84 were produced with such. Instead, later batches of T-84's composite armour is composed of special purpose rubber sandwiched between steel and alloy plates. The exact comparison of new and previous armor performance is not known and highly depend on performance of dynamic armor which continuously improved. More details
