About uboat.net

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.

Improved U-boat patrols page

Greatly improved the U-boat patrols pages. Now it shows the boats at sea on this day in 1942 for example. Also U-boat markers on the patrol maps show more details on patrol, such as if the boat was lost on this patrol.
