OK fair enough but I've also found this......

http://www.sinodefence.com/army/tank/type96.asp

The Type 96 has an indigenous smoothbore 125mm/48-calibre gun with
autoloader of Russian 2A46M design. By introducing the autoloader to reduce
the crew to three men, more rounds are available for the higher rate of
fire. The tank can carry 42 rounds, 22 of them stored in the carousel of the
autoloader, and the gun can fire at 6~8 rounds per minute.

The main gun is capable firing APFSDS, HEAT, and HEAT-FRAG. The more recent
BK-27 HEAT round offers a triple-shaped charge warhead and increased
penetration against conventional armour and explosive reactive armour (ERA).
The BK-29 round, with a hard penetrator in the nose is specially designed
for use against reactive armour, and as an MP round has fragmentation
effects.

......the Type 85-III, incorporates features also found in the newer Type 90 tank, including a larger 120mm smooth bore main gun capable of firing APFSDS, HEAT, and HEAT-FRAG. The more recent BK-27 HEAT round offers a triple-shaped charge warhead and increased penetration against conventional armors and ERA. The BK-29 round, with a hard penetrator in the nose is designed for use against reactive armor, and as an MP round has fragmentation effects. If the BK-29 HEAT-MP is used, it may substitute for Frag-HE (as with NATO countries) or complement Frag-HE. With three round natures (APFSDS-T, HEAT-MP, ATGMs) in the autoloader vs four, more antitank rounds would available for the higher rate of fire. A stabilized image intensification sights allows it to engage moving targets while in motion. A GEC-Marconi Centaur fire control system is available. British Barr and Stroud thermal based FCS can be fitted. The Type 85-III uses modular composite armor, and some reports suggest the incorporation of reactive armor.

Nor indeed are these the most deadly devices in the Iraqi theatre. Not least
of these is the standard BK-29 HEAT-MP round, a 125mm Russian shell used by
the T 72 tank. In dumps and caches all over Iraq, there are estimated
hundreds of thousands of these shells, already in the hand of insurgents.
One of these shells, suitably positioned, and detonated by a remote device,
can easily take out an Abrams or Challenger Main Battle Tank and, indeed,
several Abrams have been lost to these and similar devices - one only last
month.



So it would seem that this thing is available to just about anyone anywhere using the 125mm gun ( NOT just the T-90 )after the mind 1990's

Anyone got other info???

Maybe it has something to do with Russian markings.

I found this on Vasily Fofanov page:http://armor.kiev.ua/fofanov/

800mm RHA at 0°

So maybe BK-27 is 3BK31 round (3VBK-27)

Perhaps. I have seen various things like this as well.
This one--- http://homepage.ntlworld.com/bob_mac...enetration.htm

lists info

125mm BK-29 (1988) Tandem HEAT 65cm 13

125mm BK-29M Tandem HEAT - ?

125mm BK-31 Tanden HEAT (under development 2003) – 80cm 16

I have also seen this ......
Russian 125mm BK-29 HEAT (1990) 700mm at all ranges

This page
http://www.fas.org/man/dod-101/sys/land/row/type-85.htm

has this to say.

The more recent BK-27 HEAT round offers a triple-shaped charge warhead and increased penetration against conventional armors and ERA. The BK-29 round, with a hard penetrator in the nose is designed for use against reactive armor, and as an MP round has fragmentation effects. If the BK-29 HEAT-MP is used, it may substitute for Frag-HE (as with NATO countries) or complement Frag-HE.

So it may look like there are BK-27's and BK-29's that do the same job different ways and it also sounds like the BK-29 predates the BK-27 ( perhaps the 27 entered development first but finished development after the BK-29? )


And like many other bits of information it's difficult to nail something down 100% unless it's equipment 25 years out of date. So, we compromise...... and when we do not everyone is happy and before I start tearing into the OOB's a bit I'm going to wait a day or so and see if someone can give me good, solid info. If not,( as is most likly ) I'll aim for being "close". It's really not a hugely serious issue anyways as it only affects tanks using ERA when fired at by tanks using the DC ammo and in all cases that Russian equipment firing at Russian equipment and that wasn't an important issue in the 1990's ALTHOUGH we do have one source now claiming the BK-27's were available as early as 1988 which , coupled with the HEAT penetration we already allow the Russian 125mm Gun 88 ( penetration 68 ) which fit's quite nicely into the penetration numbers other sources claim for this shell it might be worth making the 125mm Gun 88 the start point for this

We are also faced with one very, VERY big obstacle. The weapons list in the Russian OOB is now full and every weapon there is used. There are no extras and there is ZERO chance of the weapons data being expanded to hold more weapons without screwing up more things in the game than you can imagine so adding new weapons is out of the question. The deal now is to find the best compromise with what we have so what I am faced with is deciding which gun to start applying the DC-HEAT flag to and right now I'm leaning towards the "125mm Gun 88"

Game design is SUCH fun....

just to get this striaght, the new opfire filtering features will only be available to CD owners, correct? I want to make sure of this before, I make my purchase !

[przy]

Sorry if this has already been answered. Is the opfire filtering feature already available for the latest version of SPWW2 for those like me who own the cd version? Thanks for any replies.

[DRG]

The opfire routine is a bonus feature included in the WinSPMBTv3 patch for those people who own the CD version of the game. It will not be active unless you have the CD version installed

The opfire routine will be included in the next WinSPWW2 upgrade we issue as a bonus for those players who own a CD of that game

Multicharge warheads are more effective against chobham armor too.Not only against ERA. They are capable to penetrate different layers of armor more effectivelly than solid HEAT round. (but still they will not be able to penetrate front turret armor...)
About that BK-27, i think that this is just the typo (very frequent issue with russian markings in western media) as 3BK-31 is s projectile for 3VBK-27 round, as 3BK-29 is for 3VBK-25. So BK-31,(not BK-27) is newer than BK-29.
