  Title: Cunard-White Star Line
  Passage: Cunard White Star Line, Ltd., was a British shipping line which existed between 1934 and 1949, It was created as an operating company to control the joint shipping assets of the Cunard Line and the White Star Line after both companies experienced financial difficulties during the Great Depression.  Cunard White Star controlled a total of twenty-five large ocean liners (with Cunard contributing fifteen ships and White Star ten).  Both Cunard and White Star were in dire financial trouble, and were looking to complete enormous liners: White Star had Hull 844 – RMS "Oceanic III" – and Cunard had Hull 534, which would later become  .
  Title: Ocean Steam Navigation Company
  Passage: The Ocean Steam Navigation Company (OSNC or Bremen Line) was a shipping company founded in 1847 in New York City by Edward Mills.  It was the first company to be awarded a contract by the US government for the oceanic transportation of mail.  In addition to the US contract, the company was partially subsidized by the Prussian government with the intention of increasing trade with the US out of the port of Bremen, hence the name Bremen Line.  The line began operations in June 1847 with the steamship "Washington", which completed her first eastbound voyage on June 15 and was joined by a sister ship, "Hermann".  Both vessels were slower than those operated by the Cunard Line, and the government revoked its contract with Oceanic by the end of 1847; it was later awarded to the Collins Line. "Washington" and "Hermann" both suffered mechanical difficulties, and Mills parted ways acrimoniously with the company—after giving control to investors but staying on as a manager, he tried to begin a competing line and was then fired from Oceanic.  Both the company's vessels rebuilt with improved propulsion systems in the early 1850s, but they remained slower than the competition.  After a brief upturn in business in 1855 when Cunard ships were chartered by the British government to serve in the Crimean War, competition returned to the North Atlantic the following year, as Cunard resumed service and German companies Hamburg America Line and Norddeutscher Lloyd began transatlantic crossings from German ports.  In July 1857, after losing its remaining US mail contract for traffic to Germany, Oceanic ceased operations.

She was nicknamed the "Green Goddess".  She is credited as one of the first "dual-purpose" built ships: suited to cruising, but also capable of transatlantic crossings.  After leaving Cunard she briefly served as SS "Caribia" in 1969, after which she was laid up in New York until 1974 when she was sold for scrap.
