No. It is two part ammunition, the 3.2 kg charge is in the projectile part, the supplementary charge has to be included.

JM-33 is a Japanese clone of DM-33, not a South Korean round.

I think that's somewhat questionable. When measuring the US' APFSDS or older German APFSDS (like DM13 and DM23), we can simply look at the images of cut-through projectiles or at drawings. So we know with a very high degree of correctness how long the penetrator should be. However not all...

Older (but afaik still accurate) data from Jane's abouM829A1: Weight of penetrator: 4.6 kg Length of complete round: 984 mm Length of projectile assembly: 780 mm Length of penetrator: 684 mm Sorry, but this is a completely superficial and also faulty approach. The length alone doesn't...

The length is matching with the drawing: 23.2 x 27.05 mm = 627.5 mm I think the problem in this discussion is the image quaility, because here is a nice document from the Army's Research Laboratory. It mentions that the nose section is "followed by a cylindrical section of diameter 27.05 mm (1...

If I remember correctly the following drawing was made by a soldier:

You won't find Polish 40 mm APFSDS, because Poland (like most countries) doesn't use the 40 mm Bofors gun anymore. Here is the current Bofors APFSDS penetrator: The full projectile assembly should look like this: Here is the South Korean ammunition used with their new K21 IFV...

Ok, apparently you don't understand. The forum you linked to is producing fiction about how stuff should be. People there decide to "play" the government or some part of the government of a country and then post stuff as if they would be the government. Other persons play different countries who...

You link to some random forum. It's definetly no official site, because everyone can create an own forum at InvisionFree.com... To be more exact, your link is from a forum where people simulate/pretend to be a country. The thread is from "21c roleplay". Better check your sources next time...

I doubt that this is a modern/new APFSDS: it uses a ring-type sabot. This type of sabot was used on the earliest Soviet APFSDS and was abandoned in the 1980s. The length of the penetrator is depending on how deep the round is seated in the propellant charges. You rescaled the projectile...

I do what? Reject research based conclusions? I base my statements on research based conclusions. I provide in numerous posts sources in form of scientific papers from places like the U.S. Army Research Laboratory. Thermal conductivity and grain size of WHA alloys are variable, because the...

No. If I say "It penetrates x more than a HMX shaped charge", then the HMX shaped charge is being used as reference, hence 5 equals 100%. x = 7 plates are then 140%. You are saying "The HMX charge penetrates only x percent of the CL 20's penetration".

All RHA plates used in the tests have the same thickness. The shaped charge with CL 20 penetrated 7 plates, the warhead with HMX only 5. 7/4 = 1.4

Penetrations made by 30 g HMX shaped charge (right) and 30 g CL-20 shaped charge (left). Penetration performance increased by 40%, not by 15 times nor by 60 times. So a 120 mm shaped charge with CL 20 will penetrate less than 900 mm RHA. This penetration is strongly dependant on standoff: During...

http://www.dtic.mil/ndia/2011ballistics/11770.pdf There is no "60 more powerful than RDX" because there the power of explosive is not determined by a single factor. Going by TNT equivalency, HMX is between 10% better than RDX to 60% worse than RDX. RDX is also not used as explosive in shaped...

My statement is based on the photograph of Svinets-1,2. I have not seen any evidence that there exists a longer/faster Svinets version. Length alone does not increase performance. But if all other factors are equal or very similar, then the longer penetrator will penetrate more RHA. I don't...

Seems rather like less than 10 cm penetration:

I think we should focus on the available facts: Svinets-1 and Svinets-2 are based on the currently available informations not better than M332. The projectile is shorter than that of M332, the muzzle velocity is slightly smaller or in best case equivalent while the diameter of both rounds is...

According to all claims known to me, it was a "naked" Leopard 2A6 HEL turret (which means that it didn't carry the wedge shaped applique armour normally used). Two rounds hit the location of the main sight where the armour was thinner than on the rest of the turret. One of the two rounds managed...

That is not true. It is common practice to test the armour of a tank prior buying it. The Swedes for example did test the armour of the Leopard 2, T-80U, Leclerc (prototype) and M1A2. However the armour tests are not done with full tanks, but typically only with armour modules. The Greek...
