Pictures edited for time being
These puppy's they can help confuse an active torpedo and also help make the sub do incredibly sharp turns, not to mention they can be used as silent running engines and help move in and out of port.
So what about it X mods?

And how can they confuse an active torpedo?
Also they are for low speed, not 30 knots.
Kapitan you got those pics from subpirates.com didn't you. |

They look like the VRSh-4 auxiliary propellers. They only got a few hundred HP in them, so while they may be useful for a slow pivot they aren't going to significant help sharpen the turn at high speed, assuming they don't snap off when exposed to the 30 knot current.
While IIRC they are electric, they are also tiny, four bladed, and probably not particularly carefully silenced. Deploying them also disrupts the hydrodyamics of the hull. I won't be counting on them as a "silent drive", even at a few knots. |

That i did xabbarus and i spoke to a person about them directly, i was told they were to generate bubbles or something, but yes i got them from sub pirates.
Oh and before you start accusing me or copyright i already got permission.
At this present time im speaking to Wayne about such devices. |

| I'd like to know how tiny, high revving, unskewed secondary propulsion propellers mounted behind grilles operate more quietly than a highly engineered, highly skewed, slow turning main propulsion propeller. Let me alert ONI. |

| They look exactly like the propulsers on modern cruiseship launches... just retractable and really big. |

| Most modern RN boats have an "egg-beater " to do this. |
