Main Gun Ammo - Revisited

Polynege ammunition is a "Top Attack" 120mm Shell which comes as a compliment to APFSDS shells which are design to defeat MBT beyond the line of sight. ITs versatility would also allow it to engage other targets such as Light armoured vehicles, dismounted troops, infrastructures, and low/slow flying aerodynes.

 

Polynege will meet all of STANAG 4385 and MOPI AEP 26 requirements and will be able to fire from LeClerc, Abrams M1 series, Leopard 2, C1 Arietes and other tanks armed with 120mm smoothbore guns.

 

Total Weight: 28 Kgs

Total Length: 984mm

Projectile Weight: 20 Kgs

Muzzle Velocity: 600m/s - 800m/s

Cartridge Case Type: Combustible

TPA Type: Semi-Combustible

Range: > 2000m to <7000m

Penetration Effectiveness: All NATO Targets, and Specific Targets

That is rather interesting. Who is building it? Side firing EFP, it looks like. What is the seeker?

If it's not IR/EO which it obviously is not, then I suppose it has to be MMW.

 

What is odd is how the warhead appears to be side-firing EFP, but the trajectory would seem to end in about 45-degree dive onto the target.. which would mean the EFP slug would have a good chance of landing just a bit before the target?

good call on the MMW, it is about the only thing that makes sense, given the way the nose is drawn.

 

I also agree that the illustrated trajectory looks wrong for the apparent warhead. Maybe a bad illustration?

 

I had read that modern computer designed warheads and explosives allowed for high performance side firing EFP warheads.

 

fired from tank guns. I had forgotten as soon as I read it, that it was not a mortar round.

 

About an 8km range? The drawing must not be too accurate, unless it is under aerodynamic control from launch. the angle looks too steep for most tank guns to fire, particularly in a battle field environment.

 

Still, an interesting weapon.

It looks like it reaches 100m elevation after 300m of flight which is about 18degrees. IIRC most main guns can do about 20. I just cant figure why it would not use a standard HEAT warhead. Perhaps they have a second flyover mode for close range targets?

That was what I assumed. Kind of like the midrange munition or whatever the FCS program is calling it.

[Vasiliy Fofanov]

GIAT, France.

 

Side firing EFP, it looks like.

 

Definitely. And I agree that it is inconsistent with the shown attack trajectory. Possible explanation is that there exists or used to exist a forward-firing warhead variant.

105 mm ound - right, and a round unknown to me...

 

 

That's a CTA round developed by...well...CTA

Chekh round for 125, according to Suvorov

Czech? Maybe so called 125/EPpSv-97?

Ok here is a rarity - Serbian M93 125mm APFSDS. Now my guess is that it is actualy a copy of some other round but question is what round? Israely (probable)? France (also probable)?

Is the Chinese probe\spike somewhat longer than what we typically see on M456A1 – i.e. increased stand-off? I can't tell if there is a cover over the fuse or if the Chinese have added a bit of stand-off.

 

The length difference is actually a bit more pronounced than what's portrayed in my comparison. Moreover, in the China photo, the round is rotated somewhat more toward the photographer than the rotation in the M456A1 photo. The Chinese probe therefore looks a bit shorter than if it were orientated at the same angle as the M456A1 photo.

There will be 2 mode of flight for top attack, , one parallel to the ground, and another is plunging.

Vas ist? looks interesting, but data in addition to pictures would be good.

 

Looks like rocket boosted HE, and a Cannister sort of like Ahead, some others.

Then there are also two concave surfaces? Because the side-shooting one can hardly be used in diving attack profile...

Let's put some interesting APFSDS photo on this topic.
