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
Allied Commanders pages updated
Over the last two days photos of 269 Allied Commanders have been added to their profiles. We now have 664 profile photos of those men. Most of those photos have been submitted by our readers, often relatives of the commanders, and we're most grateful for that.
New WWI wreck found?
Yahoo News is reporting that a Type IIB U-boat from WWI has been found largely intact with 23 crew members still on board. We don't know if this is really a new wreck find or something we knew already about since there is no location given. But if a new discovery if might be one of UB 27, UB 29 or UB 32 which have not been located as far as we know. See our map of WWI U-boats discovered since their loss.
Major rewrite of the site
In preparation of a wider overhaul a rewrite of the code behind the site is underway. Following that a new server will be launched and then an overhaul of the layout of the site, making it more mobile friendly for example.

Added 1,530 people on Allied Ships hit by U-boats in WWII. We now have 86,758 people in that database.

Brian has been busy adding Wartime histories on the Allied Warship section. Now 250 warships have such histories, the last one added was the US Battleship USS Iowa, also the first not for a submarine. 249 of these wartime histories are submarines of the Royal Navy (165), United States Navy (50), Dutch Navy (32) and Norwegian Navy (2). The warship section also includes over 40,000 notes displayed on relevant warships.
