GKK Westfalen

"This is GKK Westfalen. She's a Nassau-class battleship that had been modernized, which is also based on the SMS-designated ship of the same name from a century ago. Now that Werner Werman's on our side again, it looks like this ship is going to help out OFS Kestrel III and her very own fleet so that it would be able to defend the true enemy that we're going to face; the Belkan Grey Men. You heard that right, folks."

--Su Ji-Hoon, Westfalen

The GKK Westfalen was one of the newly Nassau-class battleships, the first four dreadnoughts built for the Große Kaiserliche Kriegsmarine. It would be modernized version of the SMS Westfalen after The Journey Home song being spread on all of Inkwell Isle.

It would be built as prototype battleship after the spread of The Journey Home song,and later to be completed built as combat dreadnought battleship when Werner Werman has re-joined Cuphead and all of his friends with the Kestrel fleet and fight for the OFS Kestrel III

Even though it have upgraded armors with using main modernized-naval cannons and new weapons, it could be protected by the Große Kaiserliche Kriegsmarine's destroyers.
