2E58 tank stabilizer

-
The majority of the remaining Soviet MBTs in the Russian Army featured different 2-Plane stabilizers. Ranging from the 2E42-2 "Jasmin" on the T-72B to the 2E42-4 "Jasmin" being mounted on later modernization programs of the T-72B, like the T-72BA and T-72B2 "Rogatka-2". Additionally, the 2E42-4 is also mounted on several T-90 variants ranging from the T-90 Obr.1992 being the baseline variant to the more modern T-90A. 

While the 2E42-4 was more modern than its predecessor, the 2E42-2, it still did not improve the guidance speeds for both horizontal and vertical axes. These speeds still remained the same; 3.0°/sec vertical elevation speed and 16°/sec-24°/sec horizontal guidance speed. (2E42-4 documentation)

By the late 2000s, the 2E42-4 was dated and was no longer able to perform that well in comparison with NATO stabilizers, which would outperform it. 

This forced Russia to start developing a new stabilizer, instead of using the conventional type of previously developed stabilizers based on hydraulic drives. This resulted in VNII 'Signal' opting into a new drive type, an electromechanical stabilizer based on electric valve drives.

In 2015, the stabilizer was shown at a military expo in Russia. Presented as a new stabilizer, the 2E58 would be mounted on modernized T-72 and T-90 tanks but also be used on newly developed vehicles.

This new type of stabilizer would offer better overall performance when comparing it to older-generation stabilizers like the 2E42-2 and 2E42-4;

  • Longer operation lifetime
  • The lack of lightly flammable liquids under high pressure 
  • Easier service 
  • Lower energy consumption while remaining stationary

According to the advertisement video provided by VNII Signal, the new stabilizer exceeds the previously known 16°/sec-24°/sec horizontal guidance speed of the 2E42-4 by almost 2x times, which results in horizontal guidance speed of 40°/sec, while also improving on the vertical elevation speed.

"AGAVA" - "AGAVA-2" and its confusing history

When covering Soviet sight technology there are always some interesting designs and approaches to solving an issue. It is a common fact that the Soviet Union in the 1980s-1990s was quite behind in thermal sight technology. Only in the 1990s, but to be specific in 1992, the Soviet Union now Russia started to field small batches of thermal sights on their tanks, primarily T-80Us and some of the early T-90 variants, which just recently entered service. Russia's journey through creating its own domestic thermal sight traces back to 1982.  The 1980s were quite an important time for the 'Krasnogorsk Factory named after S.A Zverev', which is still to date an Optical Engineering and Optoelectronics factory. The factory is primarily known for making domestic Soviet cameras back in the day. However, that's not the only thing that the factory has produced back then.  Close to the mid-1980s, the facility was contracted to develop new thermal sight technology for the Soviet Ministry...

T-90A - a short history of sights

  In 2004, the T-90A (Object 188A1) tank joined the Russian armed forces. It included many fire control system upgrades, a new welded turret, and improved mobility. The T-90A Obr. 2004 tank was fitted with a T01-K05 Buran-M Obr. 2004 3rd generation night vision sight, which improved over the previous T01-K01 Buran-PA sight from the T-90 Obr. 1992. --Picture of T-90A with Buran-M Obr. 2004-- In 2005, the tank received an upgrade for the sight, which became T01-K05 Buran-M Obr. 2005, with noticeable differences in the sight's housing. --Picture of T-90A with Buran-M Obr. 2005-- --Picture of T-90A diagram with Buran-M Obr. 2005-- --Picture of two T-90As, one with Obr. 2004 and one with Obr. 2005 Buran-M sights-- Above: T-90A with Buran-M Obr. 2004 sight, and behind it, T-90A with Buran-M Obr. 2005 sight. In 2006, the T-90A had to be brought to more modern standards, so the production of this model with new second-generation thermal imaging sight began. The sight was named ESSA, wh...

Object 490 "Тополь" - "Poplar"

      The project of a promising tank developed in the 1980s by E.A. Morozov. Object 490 "Тополь" - "Poplar" mockup                          The design had some primary characteristics which are worth mentioning. A crew consisting of two people - the gunner commander and the driver.  Reducing the crew to two and placing them in a compact, well-protected capsule.  The use of a hydropneumatic suspension.  In addition to solving the main task - increasing average speeds by improving the smoothness characteristic, it makes it possible to control the tank's clearance, which increases the manoeuvrability and survivability in battle.  In addition, the controlled hydropneumatic suspension by changing the trim of the machine allows you to increase the gun pointing angles in the vertical plane. Reducing the crew to two people and placing them in a compact, well-protected capsule with the ...
