History
By the mid 1960s the second postwar generation tanks superseded the medium and heavy tanks that had been developed on the basis of the war experience.
The T-72 family tanks are the most typical and wide-spread representatives of this generation. The design work on their development was started in 1967 at the Urals Carriage Making Plant Tank Design Bureau under the supervision of L. Kartsev.
However, L. Kartsev was not fated to see the tanks in mass production. The development work was continued by V. Venidiktov who succeeded L. Kartsev as chief designer.
The tests of prototypes, developed in the town of Nizhny Tagil, confirmed their high effectiveness and reliability. In 1973 the tank was designated the T-72 and adopted for service.
It has a typical general layout featuring the rear transverse arrangement of the engine. The crew consists of three men. The driver mechanic is seated at the front middle of the driving compartment which facilitates tank driving.
The tank commander is seated in the fighting compartment in the middle of the tank hull on the right side of the gun, and the gunner is seated to the left of the gun. The lower part of the fighting compartment mounts the automatic loader carousel whose introduction made it possible to reduce tank height and its armor plated area, thus improving protection without changing the designed weight and decreasing the ammunition stowage hit probability.
Located in the stern portion of the tank is the power plant compartment with a transversely arranged engine, air cooling system and input reduction gear connecting the crank-shaft with final output gearboxes.
The T-72 tank served as a base for the development of a series of tracked vehicles for military use, such as the T-72K and T-72AK command tanks, BREM-1 recovery and repair vehicle, MTU-72 bridge-laying tank, IMR-2 obstacle clearing engineer vehicle, etc.
There are cine-simulators developed for T-72 tanks in order to train personnel in driving and TKNT-3B electronic simulators to train tank commanders and gunners in firing, which will make it possible to save tank operating hours during crew training.
The T-72A tank was mass produced from 1979 to 1985. Its main differences from the base model consisted in the installation of the TPDK-1 laser ranging sight, TPN-3-49 gunner's night sight with the L-4 searchlight, continuous side anticumulative screens, 902B smoke grenade launching system, 2A46 gun instead of the 2A26M2, TVNE-4B driver's night vision device and the V-46-6 engine. The T-72M and T-72M1 export versions of the T-72A tank were manufactured with an additionally strengthened frontal part of the hull and combined armor of the turret. Tanks of this series were exported to the former Warsaw Treaty member states, India, Iran, Syria, Algeria, Kuwait, Libya, Finland and Yugoslavia.
The T-72B tank has been manufactured since 1985. Its export version was designated the T-72S. The difference between the T-72A and T-72B tanks consisted mainly in the installation of the 2E42-2 stabilizer with an electrohydraulic elevating drive and an electromechanical traversing drive instead of the 2E28M two-plane electrohydraulic stabilizer, a guided weapons system, removable container explosive-reactive armor, and the V-84 engine instead of the V-46-6.
Let us consider the combat properties of the T-72B tank in more detail.
For its firepower, i.e., the capability to defeat the opposing enemy assets by direct fire, the tank depends, from the technical point of view, mainly on the quantity and quality of the on-vehicle weapons and their servicing systems.
The primary weapon of the T-72B tank is the 125mm 2A46M special tank smoothbore gun-launcher featuring an increased barrel length and decreased normal recoil. Owing to the updating of the gun, its firing accuracy and operational properties were substantially improved. Moreover, the gun's capability to fire guided projectiles made it possible to increase the effective range of fire at armored targets to 4,000 m (compared with 3,000 m for the M1A2 and Leopard and 3,400 m for the Leclerc), with a 0.8 probability of hitting a tank-type target. In addition, the gun design enables the barrel to be replaced in field conditions owing to the introduction of the barrel-to-breech ring quick-disconnect threaded joint.
TANK T-72B CHARACTERISTICS
The gun breech mechanism permits it to be opened in two cycles, thus reducing the effort applied for the purpose. The recoil brake cylinders are secured symmetrically to the gun barrel, which favorably contributes to fire accuracy due to the absence of gun torque during recoil. The recoil system provides for free recoil until the projectile exits from the barrel bore.
The gun is provided with a built-in device enabling the crew to collimate the sight without leaving the tank.
The fire is delivered by separate case artillery rounds with hypervelocity armor-piercing (HVAP), high-explosive anti-tank (HEAT), HE fragmentation projectiles and guided missiles having a HEAT warhead. All artillery rounds have the same charge with a partially combustible case. The case, after the round is fired, is automatically ejected by the disposal mechanism through a special hatch in the turret roof.

ang masasabi ko lang... lugi ang car wash shop dyan.... ;D
-
tank lang ano pa ba masasabi ko dyan tama si kaspiyang mike lugi car wash dyan
-
isang ganito mas mahal pa sa buong philippine "armored division". (iilang apc at 4x4 jeeps) hahhah
-
dba ung blocks na nakadikit sa kanya is ung mga lightwieght na armors? lightweight nga ba?
-
parang lego.. ;D
-
Luma na.. hehe.. may t-90 na eh..
-
doon sa palabas na future weapons sa discovery, walang wala yang tank na yan.
-
ala din use yung armored nya sa A-10 laffman::
-
di pa sumikat mga russian di pa nananalo sa gyera.

dba ung blocks na nakadikit sa kanya is ung mga lightwieght na armors? lightweight nga ba?
ERA (Explosive Reactive Armor) tawag jan sa Armor na yan.
Sumasabog yan pag tinamaan ng shells at RPG, that way na dedeflect ang warhead na tumatama sa kanya.
Armor plate kasi yung nasa surface nyan at nasa ilalim at naka sandwich sa pagitan ang explosive.
