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-576 discovered off North Carolina
NOAA has reported (pdf) that U-576 (Ktptl. Heinicke), along with its last victim, the motor merchant Bluefields has been discovered. The wrecks are less than 250 yards from each other. Accordingly U-576 has been added to our U-boats discovered since their loss page.
Also, see this CNN story on the matter.
Ships hit by U-boats crewlist update
Added 1,124 people on Allied Ships hit by U-boats in WWII. We now have 75,186 people in that database.
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.
