The U-boat war in Maps


These pages contain maps dealing with the U-boat war.

New mapping system

We have a completely new map system which is loads better than any we have had before. We have already our entire U-boat losses in WWII database on this new map for you to play with.

Slowly these new maps will replace all our older maps.

For more information on this technology and installation instructions see this page.
