This meant that in contrast to previous U-boats, she could travel further afield for longer, with a payload of eleven torpedoes, an 88 mm deck gun for smaller vessels and a flak gun for aircraft. U-69 was very successful, sinking over 72,000 tons of Allied shipping in a career lasting two years, making her one of the longest surviving, continuously serving, U-boats.
