Main Battle Tanks and Armour Technology

[militarysta]

Not in now available WITU pdf's If You understand what I want to say -but this page and those pdf's are proof that there was many researches in Poland about ERA, and others.
Not all is available without some papers.

 

[Damian]

Ahhh, ok I understand, You just seen these papers, but they are not available for wider public. Am I right?

But yeah, it seems that there was (is?) a lot of research on vehicles protection... ERAWA-1, ERAWA-2, CERAWA-1, CAWA-1, CAWA-2 and this new thing PAWA-1 that seems to be some kind of passive RPG protection for... even helicopters?!

Why the hell You post something from 1999? And the title, I do not like biased articles about "the best something in the world"... there is no such thing as "the best weapon system in the world"...

Can You not post silly "the best" competitions made by people with minimal knowledge for children? It is so unproffesionalnal.

Damian, I never commented on any of that stuff. Since it is an open forum, I suppose I can share something which I found. Discussions about DM33 and 43 are still relevant but a survey conducted by an international consultancy firm is outdated and childish. What the hell?

 

[Damian]

Of course it is childish and unproffesional, no matters who made that. Where is precise analize? Any data? No... just bunch of guys sit together and decide that they will do another "top x MBT's".

Inspired by Ghur Khan blog: Gur Khan attacks!



It's seams that T-72B protction wasn't briliant - of course all is relative, but 3BM26 is rather close in performance to DM23 so this weak zone is the same for both of them.

probability of penetration like >0.45 is big - for 1000-2000m, of course there was no gerrman APFSDS with 250mm at 60. (about 500mm RHA for 90.). DM23 have smaller value, DM33 have no more then 230mm at 60. for 2000m, maybe for about 1000m this ~500mm RHA was possibe.
Hmm -any ideas?

 

[militarysta]

And there is another question...

If protection T-72B looks like on Ghur Khan blog article, and this draw bellow, what about erly T-90 with cast turret?
It's just T-72B on steroids, not new tank, with new turret (like T-90A).
It is possible that it looks that:
?


Second:
If for T-72B is ~>0.45 how about the same in Leo2? Weak points in Leo-2A4 are smaller then in T-64, T-72 and erly T-90...

ps. In T-64 it's look even worse.

 

[militarysta]

Well, this areas are almoust the same (in m2).

 

[Damian]

Nice one! Can You do similiar for other Western MBT's?

Unfortunetly I have problems with mu computer where I have all drawings etc. I need to reinstall OS, so for some time I not will participate often in discussions.

@Militarysta, I recived Your message on comunicator, however as I said I have problems with computer, send me message again, I will read it later, or send me PM on one of forums.

Can anyone make out far left AP rounds..

Look Very out dated.. .

on 80% it is 3BM42

3BM42 (3BM44) "Mango" : (core lenght about ~574mm)
~580mm RHA na dystansie "0" (instrukcje wojskowe*)
~460m RHA na dystansie 2500m (instrukcje)
~450mm RHA na 2000m (my)
~500mm RHA na 2000m (btvt)
~460mm RHA na 2000m (Mariusza Magiera "Współczesna amunicja czołgowa")
~520mm RHA na 2000m ( Tank Protection Levels)
~450mm RHA na 2000m (wikipedia)
gwarantowana (guaranted) 450mm RHA na 2000m (Vasiliy Fofanov's Modern Russian Armour Page)
osiÄ…gana (max) 500mm RHA na 2000m (Vasiliy Fofanov's Modern Russian Armour Page)

Yes it's old - ~1986r.
ps. this "black" APFSDS it's not 3Bm42 -it's trening APFDS, I was writing on this APFSDS from a picture under this "black" apfsds.

Were the plates spaced? Paul L. writes here that penetrating multiple spaced plates is harder than penetrating homogenous plates, i.e. the penetrator will errode a little bit after every plate, depending on the exact design somewhere between 70% to 230% of the penetrator diameter (~70% also for DM33).

I found it.
This photo is from ATM Spike test in Poland, but whole "test target" is propably the same like for DM-33:



stack of plates RHA - all 450mm thick - so there is 9 plates each 50mm thick. The angle of impact for Spike was near to 60-90.

Thanks. The theory that the lower values from WITU come from a spaced plate arrangement is probably wrong. Still the plates might be harder than "German RHA" or WITU uses more strict penetration criterias (like 80% of the rounds will punch through the steel plates).

T-90MS for India..!!!

Tetris camo is really famous in India..

 

[Killswitch]

It would be great if a uniform camo could be made and issued to the forces. It would have to have different colours for desert, plains, jungle, mountains etc.

The amount of camo schemes used by the army on its troops and kit is huge.

@methos

I was wrong - it's seems that new 120mm APFSDS is redy in Poland:

Amunicja 120 mm

As I remember this "new" polish 120mm APFSDS could penetrate about 540-560mm RHA at 90. on 2000m. It's almoust the same like rejected DM-43. And in WITU there are study about very very interesting new sectional core(rod) for 125 and 120mm APFSDS ammo.
