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
Just before the start of the new year, detailed Allied warship history number 500 has been added to the database. This was for the battleship HMS Nelson. For a complete list of these 500 detailed Allied warship histories see this page.
In 2024, we will, of course, continue with adding more of these Allied warship histories to the database. Besides that revisions of the current Allied warship histories will also take place. For instance at this moment work is ongoing on British and other Allied Navies submarines that had been operating in the Mediterranean. The pages of several of the British T-class submarines have recently been revised.
To aid in our research a total of four weeks of research at the National Archives in London will be undertaken in the first half of 2024. Main focus will be on photographing convoy files. Besides that in 2023 some documents have also been ordered from the Canadian and New Zealand Archives and some more will be ordered in 2024. Also there are plans for a two week visit to the Canadian Archives at Ottawa in 2025.
