The Prinz Eugen was launched in August 1938 for Nazi Germany's Kriegsmarine. The ship was named after the 18th century Austrian general, Prince Eugene of Savoy.
One of Prinz Eugen's most noted moments was her first war mission, Operation Rheinübung, a sortie with Bismarck into the North Atlantic to intercept Allied shipping to England. Although the pair managed to sink British battlecruiser HMS Hood and damage battleship HMS Prince of Wales, the operation ended with Bismarck's demise. This is why she refers to Bismarck as onee-sama in the game.
She is one of the only few large German bluewater ship to survive World War II inact, being later repatriated to the US in 1945. She were later sunk as a target during Operation Crossroads nuclear test a year later.
Prinz Eugen is sometimes depicted with pudding due to a pun in Japanese. Pudding is "Purin" (プリン) and Prinz Eugen is "Purintsuoigen" (プリンツオイゲン).
Her damage CG (post #1845804) is based on the wreck of the real life Prinz Eugen; it lies upside-down in shallow water, with only its stern exposed. Her medium damage pic is also the source of a nickname, "Puriketsu Eugen / Puriketsu-chan / Puriketsu", which means "cute butt" in Japanese slang.
She is one of only about five WWII shipwrecks that are visible above water, one of them being Kikuzuki who is in the game as well.
Shimada Fumikane, Prinz Eugen's artist, described her design on his Twitter as "a compact and little Bismarck" ([1]). This is a reference to how historically, the British mistook the Prinz Eugen for the Bismarck during Operation Rheinübungn ([2]).
