Common variant with an uncommon upgrade.

-


 
The picture shows T-90A tanks that belong to the latest T-90A upgrade batch from 2010. These are the so-called "T-90A with PTK" or "Object 188A2". Their difference is that they were equipped with a software and hardware complex for the interaction of the automated process control system. This allowed better communication between different tank crews. The actual upgrade batch of T-90A's with this system stayed relatively unknown, while only appearing several times during training in the South of Russia. It's unknown how many T-90A Obr.2010 have actually been made and sent to the Russian Armed Forces. 

According to GRAU Index, 2 T-90A variants exist with the "ПТК" System.
Main Battle Tank T-90A (with software and hardware complex PTK-T-2)

1. - digital PTK antenna. Installed in the rear of the turret behind the commanders remote controller heavy MG.
2. - normal communication antenna. The photo shows only the spring input, which is only available for antennas on tanks with PTK
3. - GLONASS satellite navigation antenna.


Command Variant T-90AK (with software and hardware complex PTK-T-1)

1. - the PTK antenna is on the left side of the turret, and the spring-cocked antenna is on the rear of the turret (the t-90A with the PTK is the opposite).
2. - a diesel generator set is installed to provide power to the commander's equipment without using the main engine (APU).

BMP-3 with "Karkas-1"/"Karkas-2" ERA packages

-
Image
  Shown at an exhibition in Omsk in 2001. ERA  blocks are located on the side and frontal parts of the hull and turret together with rubber fabric and lattice screens.  Additional protection significantly increases the survivability of the BMP-3. Advertising information of those years stated that the BMP-3 with the "Karkas-1"/"Karkas-2" was capable of withstanding the impact of HEAT grenades (RPG) with armour penetration up to 550 mm.  Also, reactive armour blocks increase the armour's resistance to damage from bullets of 14.5 mm calibre. Only known image of a BMP-3M swimming with the additional armour package. Further topic on BMP-3 ERA package

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

Image
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

BMP-3 ERA topic continuation

-
Image
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 50 m within 180 ° fire arc Areas covered by slat armour and steel plates 12.7mm B-32 rounds at 35 0m within 180 ° fi
