Name talks that it`s BB-1, but I compared characteristics with BM-1 and I think it`s mistake in album. And on the next page BB-1 bomb with characteristics for BB-1 bomb.

Ehhhh I wasn`t so fast and didn`t add information about fuze K-3. I don`t have infoamrtion about K-3 fuze, but I don`t think that K-3 the same as K-3M, as Dreamk wrote above.
Probably he has evidence of it and also can translate instruction of K-3 from Russian on English :)
Fuze K-3M has 4 tetryl blocks, 80 g each of them.
 
Yes, the data on the manual refer to the K-3M. The K-3M replaced the K-3 in 1953, and its main difference with the K-3 was an increased depth range: 10m to 330m instead of 210m for the K-3. the K-3M was (and still is) used on BB-1, BPS, RBM and RGB-12 depth charges.On the first page of this manual, there is specific mention of the BB-1 depth charge. Both BB-1 and BM-1 used the same fuzes, but BM-1 may have been retired for active service before 1953.

I know for what and when started to use K-3 and when ended. And I have I have good cutways with depth charges. Maybe you have them, but why the didn`t add them to topic?
Or you decided to translate for me from my native language infrotmation on English and explaine difference between fuzes?

Does anyone have any idea what kind of cartridge/charge system was used in BMB-1 and BMB-2 launchers to fire the depth charge?
