Soviet torpedoes, were just like the italian one modified: they was purchased in '30 by the torpedo fabric of fiume,(italian whitehead torpedo fabric. silurificio di fiume now in livorno) and so purchased rights, and start to produce of their own. italians didnt use tdc, like the british (british torpedoes had a maximum angle of 10 degrees, indeed in we dive at dawn campaign you should fire "at eye".)., and so the russians using italian whitehead torpedoes copy, they didnt have torpedoes like germans or us. (yes, fascist italy and soviet russia was heavily involved in naval projects together. russians was the main partner to purchase ships, weapons, etc by italy. also the 100 mm and 45 mm guns, the tashkent was built in livorno in '40, and the officer that tested it, later commanded a mas motor boat that attacked it off sebastopol 2 years later. and in '20-'30 many soviet officers come to naval accademies in italy, training on submarines too. in early '30 they would purchase also some sub but that was forbidden by some treaty so they didnt at the end. the dekabrist class was a result of the soviet purchase of the balilla class blueprints, with some soviet idea added, etc etc soviet russia and fascist italy was big partners in naval things, in early '20 italy was maybe the first nation to help russia to rebuilt her fleet after the revolution. they sent officers, etc to train, to purchase blueprints etc because after the revolution the fleet need to reborn.) later during the war british officers helped soviets to train, and so they too had similar torpedoes, with a max angle of 10 degrees. that s why in soviet waterway (one of my favourite mods, also because there is much regia marina inside it,) you should fire in the old way, at eye, or calculating the solution manually. usually at 1000 meters, when the target is at 10 or 350 degrees, you dont miss!
