Ok..my fault,i was not clear enough. Aft of the thruster,and the anodes,on the keel there is an obvous bulge,with a stub fin(which appears to be masked in orange tape in the photo)
What is the bulge/fin?

Careful with the smartass answers....

could be hull mounted 3d search light sonar -- as fitted to most swanky bottom trawlers (very handy for wreck finding).

Its the passive Sonar/depth gauge used for taking depth readings. Nothing fancy ....just tells you haow far away the bottom is.Eithnes sonar is carried in a large housing about the size of a pool table and is retractaable. Yeah this is a depth finder!. Looks abot right as it is a t the part of the ship that moves least just behind the bridge.

It is the transponder for the echo sounder, the hull is too fine at that point to fit it in so they had to build a special housing which you refer to as a "bulge". The orange tape is just to mask the transponder so it is not painted over.

I don't know...this wasn't a quiz...it was an inquiry. I guessed it was some sort of sonar,but i had not noticed the same feature on Emer,who also lacks the bow thruster.
Thanks to the in house experts for their assistance.

Negative, It's actually a Casting Recovery Horn for clandestine insertion or recovery of divers. Notice the high viz glint tape surrounding the horn, which protect the device while out of the water.

No seriously, Most armies have midget submarines, we've got midget divers;)
