The Submarine badge was introduced in 1939. It was distributed to crew members of submarines in the German Navy. The requirements for recieving the award included the participation in two ro more missions against enemy forces.

Unfortunately submarine badges have been reproduced almost to perfection. Some of them are so good that the only difference is in the color (shade of yellow), which means that the person must be very familiarized with the correct badge.

The badge was normally stamped with the manufacturer's name behind the submarine.

The badge came wrapped in brown paper in a blue presentation envelope. The picture below on the left portrays the bag and paper. The picture on the right shows the back of the bag where the name of the manufacturer is located on the corner of the presentation envelope.

ATTENTION:
There is some debate as to the authenticity of this badge. The following are the points in question:

the U-Boat badge by Schwerin Berlin is in fact a reproduction from the early 1970's. Schwerin Berlin only used for example vertical pins and not horizontal. Only Imperial U-Boat badges by firms such as Walther Schott used horizontal pins. Also the eagle is definately not of Schwerin Berlin design. Original eagles by this firm have heads almost looking like a parakeet. Plus the earlier awards were always fire-gilted.
