What color are U boat torpedoes?

Hi ;

     I am not sure about " U " boats , But the ones on my old ship were Bare metal with a black painted warhead .They would slather the thing with grease and then slide it in the tubes. The little prop on the very tip was kind of a silver color .The grease on the body made them look like very old bronze mixed with silver .     T.B.

Here is a good wartime color photo

I'd say a bare steel body, and obviously has some grease or some similar substance slathered on the exterior for corrosion protection. The warhead is not visible here, but other photos show some bare metal in a differing shade, and some painted in a dark color. Most likely something along the lines if Dark Gray RAL 7021. Or perhaps one of the medium grays used by the DKM.

Hmmm, that’s a good question. I see pics of silver, gold and silver, gold, silver and grey, grey, grey and black, gold and black. I’m not sure you could go wrong here.
