KMDB T-84 BM Oplot-T - Royal Thai Army’s Stronghold
Hi and welcome to my 25th suggestion, which is about the Thai T-84 BM Oplot-T, hope you like it.
First of all:
- This is a suggestion for a Vehicle we could see in game at some point in the Future , that doesn´t mean next Patch or somewhere in the near Future
- Feel free to share more Information and / or correct me if something is wrong

The post T-80 tank era witnessed a drive toward diesel alternatives due to the evident shortcomings of gas-turbine engines. Initiating various projects in the mid 1970s, Leningrad Kirov Plant (LKZ) and Omsk Transport Engineering Design Bureau explored diesel options like the Obj. 219RD and the Obj. 644, respectively. However, focus remained on the gas-turbine engine, supported by Defence Minister Dmitry Ustinov.
Simultaneously, Kharkiv Morozov Machine Building Design Bureau (KMDB) started work on the Obj. 278, with an 6TD 1000hp diesel engine. Yet, it was overshadowed by the more advanced Obj. 476 and later the Obj. 478M, equipped with more advanced systems but abandoned due to cost concerns.
Post Ustinov’s demise in 1984, the Ministry of Defense turned serious about diesel equipped T-80s. In 1985, the government approved the diesel powered T-80U project, resulting in prototypes like the Obj. 478B and Obj. 478A. Despite initial issues, the Obj. 478B variant entered service; later showcased in the 1990 Moscow Victory Day Parade and the 1991 Soviet coup attempt.
KMDB’s initiatives led to developments like the T-84 Oplot, featuring a welded turret and advancements like the Obj. 478D with Aynet fire control system.
The Obj. 478DU4 gave rise to the T-84 Oplot, which had the 125 mm caliber gun replaced with a 120 mm one able to fire NATO ammunition. Trials and prototypes like the T-84-120 (Yatagan) for Turkey showed their efforts to adapt to NATO ammunition.
Before the USSR’s dissolution, the Kharkov factory continued its T-64 platform’s development, eventually producing the T-80UD with an opposed piston diesel engine, later evolved into the T-84. Over the 1990s, further enhancements led to the “T-84M”, famously known as “BM-Oplot,” with a ton of modernizations, including western derived technologies, solidifying its position as a formidable modernized tank.
The Royal Thai Army’s 2011 order for 49 Oplot-T tanks faced delivery delays, leading to reports of a potential shift to the Chinese VT-4 tank by 2017. However, Ukroboronprom confirmed the successful completion of the 2011 contract by March 2018, finishing the delivery of the final batch to Thailand.
The BM Oplot tank is a stronghold on tracks with high protection across three levels: APS, ERA, and base armor. Its active protection, called Varta, derivated from T-90A’s Shtora system. Additionally to the strong protection; laser warning systems (LWS) and non-damaging dazzlers strategically positioned to maintain the tank’s armor integrity.
A standout feature is the Duplet ERA, defending the front and sides against HEAT and KE threats. However, its bulkiness necessitated a more compact base armor; reduced to a three-layer configuration.
The focus on protection also significantly increased the tank’s weight - now being 51 tons - to compensate this, the engineers integrated the 6TD-2 diesel engine, delivering 1200hp akin to the T-64’s 5TDF but providing a power-to-weight ratio of 23.5 hp/t. This engine also features automated gear control, replacing tillers with a steering wheel, enabling neutral turns, and featuring a gear reverser for seven forward and four reverse gears; all in all, the tank is able to achieve speeds up to +70/-35 km/h. This resolves a key tactical limitation of prior Soviet-derived tanks.
Enhancements in the Fire Control System (FCS) are obvious with the 1G46-M and PTT-2 thermal sight for the gunner (and the unmistakable commander sight). While capable of firing standard 125mm rounds, the BM Oplot features unique ammunition. Notably the GLATGM, which functions as a laser beamrider, a tandem warhead and 750mm penetration behind ERA.
Furthermore, attempts to develop a more modern APFSDS round, the 3BM44U1 failed, as it unfortunately never went further than mockup stage. However, some data regarding its intended performance exists - ~630mm pen, 1.700m/s - leaving potential for its addition.

The T-84 BM Oplot-T (Obj. 478DU9-T), is the export version made specifically for Thailand. This version has slight adjustments to align with local conditions and needs; that including chnages in the radio communication system, air conditioning, and potentially other unknown minor modifications.
