also interesting bit, at some point the reinforced driver "doghouse" 

made Mk 1,2 armor scheme, it's maybe a bit off, but doubt that more than 5-10mm for main plates thickness 

Mk3 welded turret

it will be something like this +- 

red doted line - possible size of cavity

so...i found M60A1 mantlet cutaway blueprint, as all can see a lot of cavities inside...

Kharkovite is burning during exercises

same in higher quality, for those who can't understand how distinguish UD...

PZU-7 sight mount

headlight frame

spurs for tracks mounting points

also some T-80UD used as hard target at Strugi Krasniye  range

In what way exactly?

turret roof is now 78 degree, like on  T-64/T-72, and it's weakned zone even for old 125mm APFSDS and HEAT

+ areas of roof where sights and commander cupola instaleed has even less(much less) inclanation angle

On the old turret the cheeks barely even covered the Gunner and Commander who sat mostly behind the flat zone which became very thin as it go closer to the mantlet

what ? do you know the constuction of turret ?

Atleast to weakened zone is now smaller.

nope, bigger than older turret

seems that T-90M turret is simply worse than T-90A in every bit in terms of protection, LOS is much lesser(due to angle of frontal modules is now 39 instead of 51 with same physical thickness of module), turret roof incline is again 78 deg instead of T-90A 84 etc...

one more but on CR1

i made drawing based on photogrammetry of tank(very low quality sadly) and it's possible that CR1 turret front is asymmetical(same as sides)...

So we may expect at least 300mm+/60

in what universe you live ? 634mm core in 654mm round where Svinets is 735mm overall round...

it's even shorter that Mango-M

s definitely sub 700 no matter what.

i'm only about turret, mantlet is simple 50mm RHA(or even less) + rotor(cradle) which can't be much thciker than 200-250mm

those "v" shaped weldments on mantlet also strange...

I would like some feedback but imo this gives a pretty good insight to the tanks turret, I will be maybe working on a full analysis of the turret mantlet soon if I feel like it to see an accurate representation of its armor

there not much to "analyze" LOS without backplate us 700-ish so... mantlet is simple weakspot without any magic

look closely on driver in BMD-4 when it ride 

because of 6TD they added an actuall barbette to lift turret...

M1 turret

experimental 120mm APFSDS tested in 1968

so 105mm APFSDS has a name 33V10(blueprint name) 480mm from tip to fins 38 diam 4,47kg flight weight, 6,4kg projectile with sabots

Die Soll-v0 = 1470 m/s ist mit diesem TL-Aufbau NICHT ZU REALISIEREN, fall nicht der zulassige Temperatubereich fur das Shciessen eingeengt wird. Die Abhangigkeit der v0 von der Mun-te, peratur war mit dV = 3,4m/s pro C extrem hoch. Einzelwerete siehe Anl. 3 und 4. Die Truppenversuchsmunition wurde beshalb nur mit einer V0=1390 m/s ausgeliefert. 5.4.1 Einplattenziel(VTL-Material) Die Durchschlagsleistung der KE-Munition wurde im direkten Vergleich, d.h. jeweils auf derselben Pz-Platte zur PART 105x617, DM13 erprobt. Durch Reduzieren des TL-Gewichtes wurde die v bei der APDS-mun Auf Vz = 1294 m/s entsprechend E = 2000m und bei der KE au Vz = 1290m/s eingestellt. Die KE-Geschosse durchschlugen über den gesamten Winkelbereich um ΔD= +25mm dickere Pz-Platten als die APDS munition.

Ziel 1(NHS) und III(NMT) wurden durchschlagen. Ziel 2(NDM) zeigte max.Beulen an der Plattenruckseite. Eine V-steigerung in mind.50 m/s erscheint notwendig, um auch dieses Ziel zu durchschlagen. Die Verlgleichsmunition DM13 hat nach den vorliegenden Ergebnissen keine Chance, je ein STANAG-Ziel zu durchschlagen.

It was only a concept study with the 152 mm cannon and never built. The nickname was Leopard 2 Eber according to Ministerialdirektor Eberhardt.

of course 

CR1

and the hull
