During both "World" wars, Germany relied primarily on its U-boat (submarine) force. Underseaboat, I think many called it.
It did have a regular navy with above water ships too. The battle of Jutland demonstrated that, but the regular navy didn't see much use in WWI, as the British Navy, even bigger and more monstrous, effectively shut it away from action.
But WWII? Germany's navy was pretty...well-armed, we shall say. Bismarck happened to be the largest Battleship assembled, violating international treaties (not that it really mattered). Its sinking was very big news.
It did not have, however, aircraft carriers and naval engagements on the order of the Japanese-US naval engagements.
