Wreck of U-676 and U-745 discovered

In late 2012 a Finnish diving team 'Badewanne', after 10 years of searching, reported they had found both U-676 and U-745 in the Baltic south of the Finnish island of Hanko. Both boats went missing in early 1945 with all hands lost. The boats were apparently lost in the Finnish/Soviet minefield 'Vantaa 3' laid by Finnish mine layers Louhi and Routsinsalmi on 12 Jan 1945.

We're trying to find proper positions on the boats.

Attacks on this boat and other events

5 Oct 1944

The boat claimed two Soviet planes (an Il-2 and a Pe-2) shot down near Ă–sel island in the Baltic. The U-boat was acting as a convoy flak escort.

1 recorded attack on this boat.

Men lost from U-boats

Unlike many other U-boats, which during their service lost men due to accidents and various other causes, U-676 did not suffer any casualties (we know of) until the time of her loss.
