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
U 3523 discovered of Denmark
The wreck of the type XII U-boat U-3523 has been located in 400 feet off the danish island of Skagen, slightly west of the estimated sinking location. She joins many other discovered U-boat wrecks post-war. A danish source with nice illustrations and scans showing the boat on embedded in the sea floor.
U-boat successes map improved
Improved the map of ships hit by the most successful U-boats. We only have A-Z (26) markers labels and the map had a problem if asked for more than that (ships would be missing on map). Now ships after the 26th are shown with a plain marker. See successes of U-107 for example. 43 hits by only 26 names labels, now all 43 are visible and working. This affects about 20 most successful boats. This will be improved further soon.
Made big changes to our maps. 3 of them now show allied ships sunk in the area in question. Check out those example: Caribbean, US East Coast and the Barents Sea/Arctic. Scroll to the bottom of each page. Hope you like it!
Convoy route maps improved
Improved the convoy route maps quite a bit. Now all the ships on that route hit are shown in colour by year. See the heavily attacked route HX for example. Convoy maps now show labels (A-Z) matching the list of ships above, see HX-79.
WWI Commander search improved
Added the WWI U-boat Commander search into the WWI sidebar, it was too difficult to find before. Made it a lot faster and it also shows each man's U-boat command.
