Ah okay, now I understand. Sorry then I got this evil language barrier.
Look, Daumann was and is the producer of the Rheinland ships. With huge yards like Oder or Alster they can construct the huge ships. But they compete with ALG Waste Disposal for the next generation battleships.
ALG engineers are planning to construct a shipyard out of Dortmund station, to be able to produce the ships on their own. Due to their alliance to Kruger, Gateway and the IMG they are abled to get all neccessary resources.
This is at least what the lore tells us.
I am concluding, that the next generation of Rheinland ships WILL look differend, but will have a similar base. Jinx' proposal is such a ship in my opinion, as it involves old parts and new parts.
Due to the war with Liberty, which can not be won with insame masses of metal, Rheinland needs smaller, but movable, practical and reliable vessels.
