T-72B3

Upgrading the T-72B to the T-72B3 level costs 52,000,000 rubles in 2013 prices, of which 30 million rubles. spent on overhaul of the tank, the remaining amount is spent on the purchase of new devices selected by the customer ^[6] .

The volume of the control compartment is 2 m³, the fighting compartment is 5.9 m³, the engine and transmission compartment is 3.1 m³; total reserved volume - 11 m³ ^[7] .

Monitoring and communication tools

The tank has a multi-channel PNM Sosna-U sight , developed by the Belarusian company Peleng OJSC and manufactured by the Vologda AO VOMZ ^[8] , which includes a target tracking automaton (ASC) and a thermal imaging channel with a Thales Catherine FC camera ^{[9] [ 10]} . The TPD-K1 of the 1A40 complex from the T-72B tank was left in the OMS . The sight of the tank commander is TKN-3MK, which is a modernization of the Soviet TKN-3 sight with the Double system and the 2nd generation image intensifier . The driver’s mechanic received a night binocular surveillance device TVN-5 ^[11] .

The communication system consists of a VHF radio station of the R-168-25U-2 “Aqueduct” range. It includes 2 transceivers. Provides open, disguised or classified radio communications. It has been produced by the Ryazan Radio Plant since 2005.

Chassis and engine

Caterpillar tracks , traditional for the T-72 family, are replaced with new ones with a parallel hinge to improve performance and increase resource. Four -stroke V-shaped 12-cylinder multi - fuel liquid-cooled diesel engines V-84 -1 with a capacity of 840 liters are installed in the tank . with. providing a specific power of 18.88 liters. s / t ^[6] .

In 2017, T-72B3 tanks began to install a V-92 C2F engine paired with an automatic gearbox, which significantly increased reverse speed, on the Uralvagonzavod modernized by the Scientific and Production Corporation Uralvagonzavod ^[12] .

Armament

The gun is a 125 mm 2A46M-5 smoothbore gun with improved ballistics and a resource. Thanks to the modernization of the AZ, it became possible to use new “elongated” armor - piercing armor - piercing projectiles of the Lead-1/2 type ^[13] . A weather sensor and a modern ballistic computer were installed, the weapon stabilizer was improved, a target tracking automaton (ASC) was introduced, as a result of which the accuracy of firing increased significantly compared to the base model. Open type anti-aircraft machine gun remained unchanged.

According to order no. 31603190542 of the Uralvagonzavod in the procurement register, Omsktransmash must upgrade the T-72B to the level of T-72B3. Under the terms of the agreement, the completion of the modernization is planned before the end of 2016. Repair price - ₽ 2,525,984,345.88 (78.9 million per tank). The modernization of the tank includes the installation ^[14] :

• sights "Pine-U" and 1A40-4;
• target tracking machine;
• radio station R-168-25U-2 and a complex of hardware and software AVSKU;
• guns type 2A46M-5-01;
• anti-aircraft machine gun 6P50 "Cord";
• engine V-92S2F (1130 hp) with systems that ensure its operation;
• display complex driver and television rear view camera;
• caterpillar tracks with slanting lugs and driving wheels with improved cleanability;
• side body screens with integrated Relict-type dynamic protection modules and lattice projection screens of the MTO body;

Completing a single spare tank kit:

• additional modules of dynamic protection in a “soft” case, which increase the resistance of the side projection of the case to anti-tank cumulative means, with the possibility of their equipment and hanging in operating conditions;
• dynamic defense modules and lattice screens of the tower, increasing its resistance to anti-tank cumulative means and installed instead of the spare parts for the tower, depending on the nature of the task.

Also:

• finalization of the AZ, ensuring use with products S-1 and S-2;
• completion of tanks in terms of ensuring mine resistance, at which the specified event has not been completed;
• changes in the design of tanks, taking into account product modifications and years of release not specified in the contract, are not allowed, with the exception of cases of termination of production and the inability to restore full-time components.

•   Russia : About 1000 units of T-72B3 and 150 units of T-72B3 mod. 2016, as of February 2017 ^{[15] [16] [17]} .
•   Belarus : since June 2017, 4 units of T-72B3 arr. 2016 ^[18] . March 26, 2019 received another 10 units of T-72B3 arr. 2016 ^[19] .
•   Serbia : it was planned to donate 30 units of T-72B3 ^[20] .
•   Syria : some, as of 2017 ^[21] .

• In November 2014, Armament Research Services, based on photographs of the 24 channel and the Vesti video, published a report on the use of T-72B3 in armed conflict in eastern Ukraine on the side of self-proclaimed republics ^[22] .
• In the spring of 2017, evidence appeared of the use of the T-72B3 by Syrian troops ^[21] .
• In the summer of 2018, they were seen in the battle formations of the Syrian army in the Golan Heights area , bordering Israel ^[23] .

T-72B3 arr. 2011: In total, of the innovations there is only the Sosna-U sight and modern digital communication systems, as well as an automatic loader (AZ) upgraded for new shells and an upgraded 2A46M-5 cannon, a new CBV with a weather sensor, everything else 30 years ago from the base model.

There are no GLONASS receivers for the crew to determine the location of the tank. Instead of the new V-92 C2 engines (1000 hp), there are B-84 -1 engines with a capacity of 840 liters. with. after major repairs. According to the GABTU , the installation of old engines in tanks occurred due to the late conclusion of a contract with Uralvagonzavod. Instead of the modern “ Relict ” dynamic defense, the old “ Contact-5 ” stands.

The T-72M1 tank, designed for Algeria at the same price, is equipped much better. In the Russian version of modernization, electronics is far behind modern tanks ^[6] .

T-72B3 arr. 2014:

T-72B3 arr. 2016:

• T-72B3 arr. 2014 (2014) - an upgraded version of the T-72B3 for tank biathlon . It differs from the basic version by the presence of a panoramic thermal imaging device of the commander, an engine with a capacity of 1130 liters. with., an automatic gear shift and a motion control system with a speech informant of critical operating modes of nodes ^[24] .

• T-72B3 arr. 2016 (2016) - version with Relict dynamic protection, 2A46M-5-01 gun, V-92C2F engine, automated gearbox, digital display and rear-view television camera ^{[14] [15] [25] [26] [27]} . It was first introduced to the public at a military parade on Red Square on May 9, 2017 .
