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.

U-boat commander updates
In a major update Rainer compiled a list of 172 death dates for German U-boat Commanders of WWII. See partial updated list. We also did a few other improvements (estimated/rough date to full date, minor spelling errors for 2 men ...). We often get e-mails asking if a certain commander is still alive today, this should answer some of those. Sadly fewer and fewer are alive today. Of the 268 still with unknown fate the youngest would be 90 years old.
