The main tank. Software developed by KB "Uralvagonzavod" (Nizhny Tagil) under the leadership of V.I.Potkina research under the theme "Improving the T-72B" (given by a decree of the USSR on June 19, 1986). Prototype tank - "object 188" - created on the basis and as a modernization of the tank T-72BM and originally was called the T-72BU ("T-72B Improvements").
Modernization has touched FCS - FCS 1A40-1 replaced by a unified with the T-80U / T-80UD MSA 1A45 "Irtysh" with completion under the automatic loader T-72BM. "Object 188" was developed in parallel with the tank "Object 187", which is more than be thought of deep modernization of T-72BM. Test "object 188" started in January 1989 and continued until the fall of 1990.
The tests took place at the site of the tank by "Uralvagonzavod", as well as in Moscow, Kemerovo and Jambul regions of the USSR (total mileage of about 1400 km). Decision of the Ministry of Defense and Ministry of Defense Industry of the USSR on 27 March 1991 T-72BU recommended to the adoption of the USSR Supreme.

T-90AM / "modernized T-90" on the show in Nizhny Tagil, January-February 2011, published on 31.08.2011 ( http://gurkhan.blogspot.com). The main tank T-90S at the exhibition of military equipment Omsk in 2010 ( http://worldwide-defence.blogspot.com ).
After 1991, the introduction of a series of "Object 187" was abandoned in favor of T-72BU . Razarbotok touched by "object 187" was used later when creating modification of T-90 and other types of equipment. Based on the experience of combat employment of tanks T-72during "Operation Desert Storm" (1991) CB "Uralvagonzavod" has made improvements "Object 188" - set complex optical-electronic suppression TSHU-1 "blind-1."
Repeated tests "object 188" held since 20 sentbyarya 1992 At the request of the President of Russia Boris Yeltsin replaced with the name of the tank T-72BU on T-90 and CM Resolution №759-58 Russia on October 5, 1992. The main tank T-90 into service. The same resolution defined the possibility of export deliveries modification of T-90S. Tank put into production at "Uralvagonzavod" in November 1992. In 1995, the Russian Defense Ministry chose the T-90 tank as the core. By default, T-90.

Crew - 3 people (a driver is in the driving compartment in the middle, the gunner and tank commander - are in the tower on the left and right side of the gun)
Place commander, gunner and driver's seat in the T-90A (model 2004), the 19th Motorized Rifle Brigade. Vladikavkaz, North Ossetia, April 28, 2011 (photo - Denis Mokrushin, http://twower.livejournal.com ).
Design - T-90 made by the classical scheme for the Soviet tanks - the separation of management from the body attached to the roof of the driver's seat is placed in the front, fighting compartment with a tower in the center of the tank, the engine-transmission compartment in the rear. The tank has a small amount booked. Booking hull and turret is made of three types of materials - multilayer composite armor, armor and katana normal casting. Form T's hull 90 and its arrangement is similar to T-72, but through the application including multilayer composite armor The security above.
Welded housing is box-shaped, with a wedge-shaped bow with a classic Soviet tanks to tilt the upper end-plate (68 deg.). Vertical sides of the hull, the upper part of them consists of armor plates, the bottom is formed by the edges of the bottom. Feed the body has the opposite slope. The roof of the body consists of rolled armor plates, the bottom of the housing tselnoshtampovannyh, complex shape. The main body material - steel armor. The upper endplate body, the frontal part of the tower, bearings within ± 35 ° in front of consist of a multilayer composite armor. Side and roof of the tower, the hull sides also have partially layered armor.
Tower cast (T-90) or welded (T-90 and T-90A) - similar in form to the tower T-72BM , but given the location TEM 1A45T.Reservation tower combined - in front of the tower are two cavities angled 55 degrees. to the longitudinal axis of the gun, which posted packets spetsbronirovaniya "semi-active" type. The structure of the front of the tower armor with reflective sheet is a barrier consisting of 3 layers: the plate, gasket and thin plate. The effect of the "reflected" sheets may be up to 40% in comparison with the armor of the same monolithic mass. On the upgraded T-90A instead of cast, welded steel towers fitted with improved manufacturing techniques. Booked volume increased by 100 liters. On the portion of the upper frontal body parts near the sight of the driver device thickness of armor reduced (to be able to derive the unit of observation of the driver). Book also weakened the tower on either side of the gun embrasures (no combination of protection, less thickness).
On the modification of the T-90M uses a new welded turret type, enhanced reservation upper front hull, used in the construction of fire-resistant Ballistic material "Kevlar".
Booking with the fitted armor (equivalent homogeneous armor steel katana, data evaluation):
The forehead of the body (mm) Forehead tower (mm)
T-90 with dynamic protection against armor-piercing projectiles 830 800-830
T-90 with dynamic protection against cumulative ammunition 1350 1150-1350
T-90A, welded tower with dynamic protection against armor-piercing projectiles 950
New welded turret T-90M compared with welded turret T-90A ( http://tank-t-90.ru )
The sides of the body rubber-mounted screens that are installed on steel panels with dynamic protection (3 shield on each side). At the T-90M height of the two screens is increased.
Built-in dynamic protection: T-90 / T-90A - built complex dynamic protection of the second generation "Kontakt-5" (razrbotan Research Institute of Steel, 1986, Moscow). Use security features 4S22 (in the first series machines) or 4S23 (on machines later series - T-90A et al.). The explosive reactive armor mounted on the front top of the housing (12 units), the tower (forehead, roof - 8 sections) and on-board screens (6 screens). By default, the complex "Kontakt-5": TTX elements 4S22: Dimensions - 251,9 x 131,9 x 13 mm Weight element - 1.37 kg Weight of explosives in the element - 0.28 kg (TNT equivalent - 0.33 kg ) Shelf life - at least 10 years of elements to operate at mechanical shocks with a peak shock loads of 196 m / s2, when dropped from a height of 1.5 m on a concrete or steel base, in a temperature range from -50 to +50 degrees. S.
Explosive elements in 4S22 does not detonate when hit by armor-piercing incendiary bullets 7.62 and 12.7 mm, fragments of shells with RP-blowing at 10 m or more, by burning on the surface of the combustible mixture EDZ and napalm. 4S22 elements are installed in special cavity provided in the design of the tank. The weight of the complex on the T-90 - 1500 kg Number of sections DZ - 26 pcs Total 4S22 - 252 pcs. The number of sections on the main parts of the tank: the tower - 8 pieces; on the upper front - 12 pieces; on-board screens - 6 pieces. The area of the frontal projection of the tank, the overlap complex: at course angle 0 degrees - more than 55% during course corners ± 20 ° (body) - more than 45% during course corners ± 35 degrees (tower) - more than 45% Increase protection of the tank: from cumulative shells - 1.9 ... 2.0 times from armor-piercing - 1.2 times (according to the tests in 1.6 times)
Part media have information that T-90A / F-90SA complex set of dynamic protection of the third generation "Cactus" ("Relic") with elements of 4S23. This information requires additional verification.
