Identification project 4

[US-Subs]

First is a small rocket, described to me as a Russian anti-swimmer device - nomenclature?
Second is an unknown experimental. 30mm, fired from a rifled steel case similar to the 40mm grenades for the SPIW system. DBACTA?

For the first image, as per what's on the rocket, RG-55 MI (РГ-55 МИ), also seen as RG-55MI (РГ-55МИ). This is the designation for the training version of the RG-55M (РГ-55М).

Sorry, forgot to add it was developed for the seven-barrelled 55 mm MRG-1 (МРГ-1) Ogonëk (Огонёк) anti-diver system. It can also be used in the DP-61 (ДП-61) Duel' (Дуэль) single-barrelled launcher.





The RG-55 series are essentially small rocket-propelled anti-diver depth charges.



There's also a surface marker rocket, the RGS-55 (РГС-55).

The 1st (I think larger than 51mm) : I'm quite sure this round is close to Polish smoke tank defense 81mm grenades (typical markings) :

Hi,

What about this one, just a dummy or a subcaliber device ?
