When loading a torpedo on board a german u-boat it was greased NOT with vaseline , this is total nonesense but with a thick brown grease . There are several color photos of this brown grease , they first where published in the magazine SIGNAL. German torpedo tubes in WWII did not use rollers , only rails . As the torpedo was being loaded into the tube it was greased again as the tin fish that was stored below the floor plates where given a quick cleaning as not to make a sticky mess with people in constant contact with them . Greasing a torpedo before launching was not for anti-rusting as the torpedo would be blown up very shortly but it did 2 functions , first it helped slide out of the tordedo tube and second the grease helped the torpedo slip through the water with less drag . A greased torpedo has less drag in the water than a plain steel torpedo , this is why fish have a slimy coating and a surfer waxes his surf board . Both the Russian navy and the USN have both conducted top secret experiments with various polymers on torpedos and submarines to decrease the drag between the water and hull .
