Now THIS outta be interesting!
(Keep in mind this will make more sense by knowing in this hypothetical universe, the Britannic survived the war.)
As a celebratory gift to the public after the war, the White Star Line released concept art of the fourth member of the Olympic class: the RMS Oceanic (III)!
Launched in November 1921 and put into service in August 1922
Added features not found on Olympic or Britannic:
(A shrunken Smoke Room, with the excess space replaced with a dedicated First Class Library.
(The Reading and Writing room extension converted into an open-air Coffee Parlor.
(A separated bridge, similar to Queen Mary’s. [probably a bit questionable for an Olympic class ship but...whatever.]
(The pool now lavishly decorated with dark woods and a light-green Greek styled tile design.
(Redesigned First Class corridors.
(A cloak room in the elevator foyer on D deck.
(Updated galleys in all three classes.
(The Third Class General Room has been cut in half, with the excess space replaced with a library for 3rd class filled with language-to-language dictionaries and books about the “new world”.
(More public lavatories.
(A more fully enclosed 3rd class promenade deck, with those separate windows with the retractable glass.
(A more Aquitania-styled look to the superstructure.
(And finally, Forecastle deck expansions along the tops of the sides of the forward well deck.
What do ya think?
