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.

Ship removed from Ships attacked pages
Removed the British trawler Castleton from Ships attacked by U-boats when newer research shows the small trawler was in fact sunk by German Luftwaffe bomber and not U-102 that did not return from patrol and was thought to have sunk Castleton. The trawler is now found on our Ships not hit by U-boats instead.

U-boat Commander listing on U-boats updated
Improved display of WWI U-boat commander on boat pages. Now we show if they received the two highest decorations for their nation (Germany or Austria). Example is SM U 24 where two of its commander received the Royal House Order of Hohenzollern. For the WWII boats (which had this feature already for Knights Cross winners) I added the German Cross as well, see example on U 230.
