T-55AM. The new version of the modernization of obsolete tanks
July 31, 2014

Medium Tank T-55 was one of the most popular cars in its class and was able to become the main type of armor in the armies of several dozen countries. Even after half a century after the start of production of T-55 tanks remain in service with the armies of the set and are unlikely to be fully written off in the foreseeable future. However, the T-55 tanks are outdated and morally, and physically, because of what need to be replaced. Not all countries involved in the technique of this model can afford to buy a modern armored vehicles, high performance due to their high cost no less. Therefore, they may be interested in a variety of projects, implying the repair and modernization of existing equipment. One of the options for upgrading T-55 tanks with a noticeable increase in performance offers KB Omsk Transport Machine-Building, part of the Corporation "Uralvagonzavod".



Project T-55AM means for overhaul series of tanks and installation of a large number of new equipment. Because of this, allegedly, have modernized tanks are improving all the major parameters: firepower, protection level, mobility and team handling.

It should be noted that the proposed "Uralvagonzavod" modernization project cars T-55 has almost no relationship to the tank T-55AM developed in the early eighties. These two projects are alike approach to modernization, namely the replacement of obsolete equipment with new components and some of the measures aimed at improving the protection and firepower. However, projects are characterized by the modernization of the equipment used.

To simplify the conversion of serial technique T-55AM project involves the use of various accessories and systems for installation are not required to make to the machine major adjustments. For example, for a significant increase in the level of protection offered to use additional modules booking installed on native homogeneous armor of the tank. Forehead housing is proposed to further protect several removable blocks dynamic protection. Of these units should be collected wedge protection forehead and cheekbones tower. The frontal part of the body gets extra protection with a total weight of about 800 kg, consisting of 152 elements of the 4C22 "Kontakt-5". Mounted on the tower support structures and 81 element 4C22 weighing about 920 kg.

For additional protection, the housing is proposed to use a removable rubberized side screens mounted with blocks of dynamic protection. Each screen weighs more than 460 kg and is 48 elements of the "Contact-5." It is alleged that during the shelling using cumulative ammunition at an angle of 20 ° to meet the level of protection of the hull sides, covered with new screens, increased about two times in comparison with the base armor of the T-55.



The use of additional security modules and other new equipment increases the weight of the modernized tank. According to official sources, an updated combat weight of the tank reaches 40 tons. To preserve the mobility of the machine at an acceptable level in the project was provided updated powerplant.

In the stern of the T-55AM is set 12-cylinder four-stroke diesel engine B-46-5MS turbo engine, 690 hp In addition, the engine-transmission compartment must be mounted in a block of cyclones and cassette unit air cleaner. The basic version of the T-55 was equipped with a 580-horsepower V-55, which is why the replacement of the power plant can save the specific power of the machine at the same level.

To improve patency and precise modernized tank T-55AM gets updated chassis design. The new project provides for the use of feed drive wheel with new rims and power lock. Also enhanced the steering wheel and drive the bearing assembly of the first reference of the rink. Carrier Rollers offered to equip the updated hydraulic shock absorbers with high energy content and torsion of a steel grade. Thanks to these innovations, the dynamic progress of road wheels is increased to 186 mm, which should positively affect the ride and, as a consequence, the accuracy of shooting on the move. An additional factor in the cross-country, was a new track with rubber mount, reducing ground pressure to 0.76 kg / sq. cm.



Using the updated powerplant and chassis allows you to keep the characteristics of the T-55AM at the required level. Speed ​​of the car on the highway is 50 km / h, range with extra fuel tanks, barrels - 610 km. Tank can climb a 32-degree rise, move up with a roll of 30 °, to climb the wall height of 0.8 m and cross the trench width of 2.7 m. Offhand, the machine can move along the ford to a depth of 1.4 m. Use the equipment for fording depth permissible Fording increases up to 5 m.

In accordance with the design of T-55AM main weapon of the modernized tank is a 100-mm rifled gun D-10T2S using unitary munitions. The modernization of the gun gets a three-piece thermofilter casing enclosing the pipe barrel guns from the mask to the ejector. To balance the trunk with the cover on the fence breech gun is proposed to establish a relatively compact mass balances required. Using the shell leads to a marked increase in accuracy. It is argued that the variation in the emission angles of the projectile is reduced by 2-3 times, technical dissipation is reduced by 2-4 times. As a result, consumption of ammunition to defeat the purpose of reducing by 20%.

Another method of increasing the firepower of the tank is to use the new ammunition. In ammunition gun D-10T2S proposed to include high-explosive projectile OF70. This ammunition is produced by the new technology, which improves the accuracy of manufacturing buildings and there is no need to use other characters in addition to the weight of zero ("H"). All this should simplify the use of shells, to reduce training time for a shot, and improve accuracy. Projectile weighing 13.28 kg carries 2.24 kg of explosive. With an initial speed of 960 m / s projectile able to fly at a distance of up to 13 km. At undermining the body of the projectile breaks up into fragments of 3393, hitting targets over an area of ​​320 square meters. m.



In order to effectively defeat armored vehicles and fortifications at distances up to 4 km T-55AM can use shot 3UBK10-1 guided missile 9M117M. Running guided missile must be made through the gun barrel. To control the missile offer a special laser system. Missile guidance to the target is carried out in semi-automatic mode: the gunner must keep the laser beam on the target and the missile self-retained in the beam. Cumulative warhead missiles 9M117M pierce to 550 mm homogeneous armor.

As an anti-aircraft armament tank T-55AM gets setup with a heavy machine gun "Kord". Machine gun mount is mounted on the left hatch tower and circular provides guidance on the horizontal. For pointing gun proposed to use a collimator sight K10-T.

On the turret mounted smoke grenade 902B 8 "Cloud". The control panel is placed rocket launchers in the workplace tank commander. Grenades can be fired by one or gulp.

The basis of the fire control system is modernized tank sighting and observation complex "Om." Its members included several multi sights with larger magnification and field of view. It is argued that the use of complex "Om" can significantly reduce the time required for searching purposes, improve accuracy, and almost a third to reduce the consumption of ammunition.

To observe the surroundings commander of the T-55AM should use the device TKN-1 cm, mounted in the commander's cupola. This tool is based on a two-channel scheme and allows observation of the day and night. When using the night vision channel provided the observation of objects at a range of more than 600 m. Provided noise-free operation, designed to monitor the situation with the appearance of light interference.



In the workplace, the gunner must be installed two sighting device: periscope sight 1P3-7D and thermal 1PN-96MT. The first is equipped with integrated laser rangefinder and ballistic computer and provides detection of enemy tanks (side view) at distances up to 10 km. Rangefinder sight 1P3-7D able to measure the distance at distances up to 8 km. Sight 1PN-96MT is also built on the periscope scheme, but is equipped with a thermal channel. In passive mode, this device allows you to see the goal of the "tank" (side view) at a distance of 3 km. Both sight automatically calculate corrections and shift the reticle depending on the distance to the target and other conditions.

In the workplace, the driver of the T-55AM is offered to install periscope observation TVK-3. The instrument has a day and night grooves for driving the tank at any time. Night device channel TVK-3 allows you to monitor the situation on a distance up to 250 m, and does not require additional fixture. An important feature of the device TVK-3 is the ability to tank driving day and night without changing the means of observation.

Connection of the T-55AM with other combat vehicles is ensured by the radio station R-173, installed in the tower. At the request of the customer can get a fighting machine communication using digital radio station R-168. New radios provide high quality analog and digital communications, as well as less complex to operate and maintain.

It is known the existence of at least one prototype tank modernized in accordance with Omsk project T-55AM. This machine was exhibited at some shows, and also featured in the promotional material "Uralvagonzavod" corporation. However, information about orders for repair and renovation techniques for a new project no. Probably the methods proposed modernization combatant armored vehicles are not interested potential customers.
