Pg 9

[blu97]

To make things a bit more complicated there is a PG-9 and the PG-15, diference is how they are fired. The PG-9 is fired from the recoiles rifle SPG-9 and uses a tailboom with the propelant around it. The PG-15 is fired from the BMP-1 tank and uses a cartridge case. Both uses the same projectile the PG-9, same goes for the OG-9 and OG-15. First pic the diference between the PG-9 (right) and the PG-15, second pic the OG-9.

Less complicated rather than lots of confusion (or no info/lack of docs and russian language) when it comes to separated Russian ammunition and it's designation system.

73mm SPG-9 (recoilless) ammunition:
Round:
PG-9V (HEAT)= consists of PG-9 projectile and PG-9P propelling charge
OG-9V (HE-Frag)= consists of OG-9 projectile and OG-9P propelling charge

73mm 2A28 (vehicle gun) ammunition:
Round:
PG-15V (HEAT)= consists of PG-9 projectile and PG-15P propelling charge
OG-15V (HE-Frag)= consists of OG-9 projectile and OG-15P propelling charge

People often tend to confuse round and projectile designators and think one designation goes for all.

And as said before the HE-Frag is no rocket.

Taths it EOD.
Actuly the PG-9 is no rocket to but a rocket assisted projectile

[EOD]

blu97, to me it is a bore launched rocket since the rocket motor there is way too large to be "assisting" only and the external propelling charge (or better an expelling charge) is making up for the smaller part of the trajectory.

We may ask another 10 people here and I am sure we will get another 10 different opinions.

[blu97]

There is always a gray area in munitions groups and agree withe ask 10 people....

Is this a newer version or totally different? I've seen them in orange and green.

It is a lot more obvious when you see one in person. Besides the tail boom/motor section, while the PG-9 is typical of other PGs in construction - lightweight stamped sheet metal body - the OG has a heavy steel body, say similar to a 57mm recoiless or heavier.
