Modern 122mm soviet projectiles

[Vince]

I am looking for the meaning of two designation which i found in Ordata's image library.
122mm PVM-3RB (ПВM-3РБ)
122mm PVM-3A (ПВM-3A)

What type of shells are these?

Reagrds,

These are Bulgarian HF and VHF radio jammers (joint Russian as I read but not confiremd).
They are made by SAMEL90 in Samokov.
They are offered in 122 and 152mm (identical interiour parts).
The jamming device is expelled through the projectile base like an illumination shell is doing with it's load. The jammer has a telescope antenna and is working on 1.5-120MHz at an effective distance of 3.5-15.5km.

If you need more info let me know.

Hi X,

Thanks for the info.
I know the soviet RS-462 and RS-540 jammer shells and how they work. We have the RS-540 with DZV-90 fuze in our training collection.
I just haven't seen those designations yet.

Thanks again,
Vince

X,

i will take pictures in september, after my holiday ends.
The DZV-90 is an MTSQ fuze, almost identical to the V-90, but it has a shorter lower part (like the T-90) and has a black powder pellet instead of the HE booster.

@Poroch: thank you, any info is appreciated

Thanks Poroch!

I will post pictures soon about the actual 152mm RS-540 round and the jammer
