On this site you will find all the German U-boats of both World Wars, their commanding officers and operations including all Allied ships attacked, technological information and much more. You can also browse our large photo gallery and thousands of U-boat books and movies. While hundreds of U-boats were lost some of the boats are preserved as museums today.
We also have a huge section covering the Allied forces and their struggle with the U-boat threat - not to mention the Pacific war. Included there are all the Allied Warships and thousands of Allied Commanding officers from all the major navies (US Navy, Royal Navy, ...) plus technical pages and information on the air forces.
What's new on this site
Maps of ships hit by U-boats (WWI and WWII)
Finished adding both Ships hit by U-boats in WWII (3336 maps) and Ships hit by U-boats in WWI (3946 maps). This is a stop-gap until I finish a better solution I am working on.
WWI U-boat fates now also have maps again
Finished adding the new static maps to all 146 U-boats of WWI that have a known fate position, see U-29 for example.
Returned the U-boat fate maps
I have just re-activated the U-boat fates maps for all U-boats, see U-2511 for example. They are now static (fixed image) so no zoom is available for now. Working on re-adding the maps to Ships attacked, WWI U-boat fates and Allied Warships.
Google Maps dramatic pricing changes
On 16 July Google Maps increased their prices for the dynamic maps we use on the site 15-fold. I am working on solving this problem since we use the maps heavily all over the site. In the mean time I might have to disable some major map section.

We have learned that KrvKpt. Reinhard Hardegen (former commander of U-123, of Operation Drumbeat fame) has passed away on 9 June 2018 at the age of 105.
