She was protected by a total of 17,450 tonnes of steel armour plating. The newly designed heavy artillery fired 800 kg projectiles up to a range of 34.2 km and were capable of penetrating 350 mm armour at 21 km. Although the "Prinz Eugen" suffered no direct hits in the battle of 24th May, the "Bismarck", which was damaged in the bow, made for a French harbour.
In the subsequent pursuit by British ships and aircraft, on 27th May 1941 a torpedo hit the rudder and after being hit by the superior numbers of the Home Fleet she was disabled and sunk in the Atlantic about 800 km off the French coast. Of the 2,092 men on board, 115 survived.
