BMP-3 ERA topic continuation

-
This post expands on a previously covered topic, being the BMP-3 with ERA. Potentially sealing this topic until later when more information comes to light. 



ERA package components: 
  • ERA containers filled with 4S24 ERA elements, containers are mounted on the front and both sides of the hull.
  • Slat armour mounted on the rear of the vehicle protects the engine compartment.

Overall package performance: 

Protection against AT rocket-propelled grenades (RPG) PG-7V, PG-7VS, PG-7VL, PG-7VM, PG-9S and other types of grenades capable of penetrating up to 600mm RHA within a 180° fire arc. 
  • In areas covered by ERA containers, the probability of protection is at least 80%. 
  • In areas covered by slat armour, the probability of protection is at least 50%.
Protection against small arms: 
  • Areas covered by ERA containers
    • 12.7mm B-32 rounds at 0m within 180° fire arc
    • 14.5mm B-32 rounds at 50m within 180° fire arc
  • Areas covered by slat armour and steel plates
    • 12.7mm B-32 rounds at 350m within 180° fire arc
  • Ballistic protection of add-on ERA package (in the areas covered by ERA containers)
    • 23mm AP ammunition at 550m within 180° fire arc
    • 30mm AP ammunition at 0m within 60° fire arc
The entire package weighs 4,150kg. 
A BMP-3 IFV equipped with such a package also retains its buoyancy. 




4S24 ERA Element specifications: 
  • Weight: 1.36kg 
  • Probability of countering shaped-charge threats: 95%
  • ERA Element does not detonate when hit by API rounds
  • Dimensions of each individual element: 10mm x 130mm x 250mm

BMP-3 equipped with side skirts to mount ERA (ERA containers are not mounted)





ERA package composition: 
  • The package consists of 4 types of ERA blocks 
  • Steel plates with mounting brackets
  • Dampening plates for side skirts
  • Slat armour 
  • Hull roof dampening plates
The entire package has 84 ERA blocks.

"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
