Propably the most interesting was T-80B armour in turret (hull -the same as T-72A)

 

T-80B (1978-1984)

Id1rtLo.jpg

 

Psyhical thickness in the thickest place before crew comparment: 715mm

psyhical thickenss at 30. degree from turret centre - 530mm

psyhical thicnes in thinest place whit kvarc "sepcial armour": 520mm

 

Wery simple armour, heavy weight, but...cheap and effective! Material thickens effectivens is well known (vs. APFSDS and HEAT)

 

cast steel circa 270-330HB - 0,85 vs APFSDS and HEAT

kvarc "snadbars"  - 1.22 vs HEAT and 0.77 vs APFSDS

Whole turret protection looks good, very good:

 for LOS thicknes equal 715mm:
vs APFSDS: ~590mm (sic!)
vs HEAT: ~670mm


for LOS thicknes equal  530mm
vs APFSDS: ~440mm
vs HEAT:  500mm

for LOS thicknes equal 520mm
vs APFSDS: ~430mm
vs HEAT: ~490mm


And for compare older NATO 120mm rifted and 105mm APFSDS munition:

(2km, plate slopped at 60 degree (angle)  so the most comfortable conditions for penetrator, for 0. angle penetration must be mucht worse)

 

105mm rifted:

M111 (???) - 340mm RHA
M774 (1979) - 360mm RHA
M833 (1983) - 500mm RHA

 

120mm L-44 Leo-2:

DM13 (1979) - 440mm RHA
DM23 (1985) - 480mm RHA

 

In Soviets protection estimates only 30 degree was taken into account, so it has modest 420 mm vs APFSDS.

440mm circa vs APFSDS. 

BTW - I have fun couse it seems that erly M1 was less protected (in term KE) then T-80B, T-72A, ect :) Of course CE (HEAT) protection was better but sitill - 90% of estimatous where so overboosted (to big) :)

 

BTW  - this only 30 degree taking acount are qutire misteken. For example - Your favorite T-64B - values given for 450-470mm LOS (psyhical thickenss) can be biger in 115 and 130% for 0.degree...

From Andrey's site, one of proposed modernisation of T-80BV and T-64s: http://btvt.info/5library/t80moderniz.htm

 

It is basically a Kornet launcher, mounted behind turret.

In 90-s Kobra GL ATGM became quite obsolete, so this was a good idea withou limitation of gun calibre and missile size.

 Some sort of flashback to 60-s era Malutka equiped tanks.

T-80Us too receive new thermal imager.

http://mil.today/2017/Weapons52/

 

Quote

In 2016, the Krasnogorsk plant finished tests of the heat-vision sighting system Irbis for modernized tanks T-80U and T-90. The sights will be supplied to the army after 2017 under the already concluded contract, says the manufacturer’s annual reporting. According to the experts of Mil.Today, commissioning of the new sight will for the first time give Russian tankers a homemade thermal vision device based on the mercury-cadmium-telluride (MCT) matrix, which will bridge a gap between the leading NATO countries in this area.

      Hello, my friends and Kharkovites, take a sit and be ready for your brains to start to work - we are going to tell you a terrible secret of how to tell apart Soviet tanks that actually works like GLORIOUS T-80 and The Mighty T-72 from Kharkovites attempt to make a tank - the T-64. Many of capitalists Westerners have hard time understanding what tank is in front of them, even when they know smart words like "Kontakt-5" ERA. Ignoramus westerners!
       
       
         Because you are all were raised in several hundreds years old capitalism system all of you are blind consumer dummies, that need big noisy labels and shiny colorful things to be attached to product X to be sold to your ignorant heads and wallets, thats why we will need to start with basics. BASICS, DA? First - how to identify to which tank "family" particular MBT belongs to - to T-64 tree, or T-72 line, or Superior T-80 development project, vehicles that don't have big APPLE logo on them for you to understand what is in front of you. And how you can do it in your home without access to your local commie tank nerd? 
       
       
         Easy! Use this Putin approved guide "How to tell appart different families of Soviet and Russian tanks from each other using simple and easy to spot external features in 4 steps: a guide for ignorant western journalists and chairborn generals to not suck in their in-depth discussions on the Internet".

      T-64 - The Ugly Kharkovite tank that doesn't work 
       
         We will begin with T-64, a Kharkovite attempt to make a tank, which was so successful that Ural started to work on their replacement for T-64 known as T-72. Forget about different models of T-64, let's see what is similar between all of them.
       
       
       

       
       
         
       
       
      T-72 - the Mighty weapon of Workers and Peasants to smash westerners
       
         Unlike tank look-alike, made by Kharkovites mad mans, T-72 is true combat tank to fight with forces of evil like radical moderate barbarians and westerners. Thats why we need to learn how identify it from T-64 and you should remember it's frightening lines!

      Hey guys. This is my first post in this forum.
       
       
       
      I want to find out sources for 2 information.
       
       
       
       
      Firstly, a friend of mine told me about the accuracy of T-80B tested in 1980s.
       
       
       
       
       
      T-80B      1000m   1500m     2000m
                      
                      87%       66%       46%
       
       
       
       
       
      I asked him where he found this data. But he told me he forgot where he did find this since too much time passed from that moment.
       
       
       
       
       
       
      The Second one is about Russian ballistic computer's range-finding rate.
       
       
      One day, one of my friends who speaks russian quite well showed me a product info. of russian(maybe ukrainian) gunner's primary sight.
       
       
      It was written that range-finding rate of the sight after laser fired-off 0.3~3.0 seconds. 
       
       
      I totally forgot the address of that product brochure.
       
       
       
      I'd be very appreciated if you help me finding links of these information.
