NII Stali 4S24 ERA showcase video

 Earlier NII Stali announcement. 

Video created by NII Stali for the showcase of 4S24 ERA. 



Individually picked frames from the video. 

Individual 4S24 ERA plates




ERA package demonstration

Live fire demonstration using 4S24 container, located at a cedent distance from an armour plate creating a large air gap. The plate represents the side armour of an MBT. NII Stali confirms that the ERA package can be used as an all-around protective package on BTRs, BMPs and MBTs. 



The ERA block functionality was tested using a standard RPG-7 firing a PG-7VS HEAT charge with an approximate penetration value of 400mm against steel. 


Snippets slowed down for a better understanding of how the charge is countered by the ERA container. A reverse layer added. 





Post detonation effects on main armour plate. 

The ERA container and the large air gap almost nullified the potential chemical penetration of the HEAT charge. Resulting in small craters ranging from 2mm-5mm. 



Effectively the container holding the ERA is a one-time use addon which would need to be fully replaced. 


The total armour "thickness" is around 500mm from the ERA container to the armour plate. 


Interestingly enough, this demonstration only showcases the ERA performance when mounted as side hull armour, where the overall air volume is larger. Possibly the post-detonation effect would be more different if the ERA were to be mounted on a lighter vehicle like a BMP or BTR at a smaller distance to the armour plate. 

NII Stali as promised has showcased the ERA capabilities but sadly did not provide anything more valuable regarding light vehicle protection using 4S24 containers.

"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-80 aerodynamic features - Part 1

This article is the first part of a set of articles covering the engineering and methodology used to create the T-80s filtration system alongside aerodynamics to reduce airflow dust/sand contamination.  The T-80 MBT has been fielded in many climate regions. Desert climates pose a variety of variables that directly impact dust presence in the engine air filtration system. Variables include wind speed and direction,  vehicle speed,  depth and soil composition, air intake system design, and contours of the hull and turret.    Historical background:  Long-term trials were conducted in the southern Kara-Kum desert. It was determined that during  1970-1983, the quantity of dust present in the engine filtration system increased due to climate changes and weaker upper soil layers.   During the 1970s to 1980s, the Turkmen Canal underwent Soviet industrialization to build an irrigation canal and other facilities. This build-up of new infrastructure directly affected wind speeds in the ar

GTD-1000 - GTD-1000TF - GTD-1250 Gas Turbine Engines

The world's first mass-produced tank gas turbine engine GTD-1000T was created at the Klimov Plant in 1968 for the T-80 main battle tank developed By the special tank design Bureau of the Kirov plant (now JSC "Spetsmash"), which was adopted by the Soviet Army in 1976. Since 1980, a modification of the GTD‑1000TF for T-80B/BV tanks was produced, since 1986 a modification of the GTD-1250 for T-80U tanks.  GTD-1250 Engines of the GTD-1250 family as part of the power plants of T-80 tanks are in service with the armies of Russia, Belarus, Cyprus, South Korea, Kazakhstan. Turbine engine GTD-1000T/GTD-1250, which have a large volume-weight  capacity and a more favourable traction characteristic compared to diesel engines, provide T-80 tanks with interesting characteristics: - higher operational readiness - easy start-up at low temperatures (up to -40°C) - better cross-country ability on soils with a low load-bearing capacity - best noise and heat-masking qualities - increased &qu
