Russian submunition fuze




This is a Russian submunition fuze. I need to look up the documents for what type exactly.
Of this type (size) several different ones exist which may fit the same submunition.
This one is comparatively new so little is known.


Here I have found something.

9N235 submunition for 9M55K Rocket (MLRS system)

And here the 152mm artillery shell Z-O-13 (these are definately in Service with Russian Forces)


How does it work ?


Have unfortunately no detailed documents on them jet.


Can somenbody state the imprinted markings on the fuze please? If they are available of course …
