The ship was the only one of the four which was never the world's largest ship; however, she was the fastest of the Big Four.

The line was shut down in 1863 because of the success of newer, faster liners and the danger of transatlantic travel during the American Civil War.
Document 3: RMS Oceanic (1870): RMS "Oceanic" was the White Star Line's first liner and an important turning point in passenger liner design. Entering service in 1871 for Atlantic crossings, she was later chartered to Occidental and Oriental Steamship Company (O&O) in 1875. The ship provided passenger service for O&O in the Pacific until 1895 when she was sold for scrap.

Document 9: SS Baltic (1871): SS "Baltic" was an ocean liner owned and operated by the White Star Line. "Baltic" was one of the first four ships ordered by White Star from shipbuilders Harland and Wolff after Thomas Ismay bought the company, and the third of the ships to be delivered.

Document 11: SS Cymric: SS "Cymric" was a steamship of the White Star Line built by Harland and Wolff in Belfast and launched on 12 October 1897. She had originally been designed as a combination passenger liner and livestock carrier, with accommodations for only First Class passengers. During the stages of her design layout, it became clearer to the designers at Harland and Wolff that combining passengers and livestock had become rather unpopular, so the spaces designated for cattle were reconfigured into Third Class accommodations. She departed Liverpool on her maiden voyage on 29 April 1898, arriving in New York City on 9 May 1898. She spent the first five years of her career on the White Star Line's main passenger service route between Liverpool and New York, until 1903 when she was transferred to the less traveled Liverpool-Boston route, which she sailed on for nine years before being returned to the New York route in 1912.
Document 12: RMS Cedric: "Cedric" was laid down in 1902 at the shipyard of Harland and Wolff, Belfast. She was the second of White Star's series known as the "Big Four", the other three being , and . "Celtic" was the first ship to exceed Brunel's in overall tonnage, which was quite an accomplishment, considering Brunel's giant ship held the size record for almost 40 years. Except for the "Adriatic" all of these in turn, when built, would be the largest ship in the world for a short time. RMS "Cedric" was a 21,035-gross ton ship, long and abeam, with two funnels, four masts, two propellers and a service speed of . There was accommodation for 365 first-, 160 second- and 2352 third-class passengers, and a crew of about 350. She was launched in Belfast on 21 August 1902, in a private ceremony which included several guests, amongst others William Pirrie, the chairman of Harland and Wolff and Bruce Ismay, chairman of White Star Line. RMS "Cedric" commenced her maiden voyage from Liverpool to New York on 11 February 1903. This was the only route on which she was ever used, although "Cedric" was also sometimes used for winter cruises to the Mediterranean.
Document 13: SS Suevic: SS "Suevic" was a steamship built by Harland and Wolff in Belfast for the White Star Line. "Suevic" was the fifth and last of the "Jubilee Class" ocean liners, built specifically to service the Liverpool-Cape Town-Sydney route, along with her sister ship "SS Runic". In 1907 she was wrecked off the south coast of England, but in the largest rescue of its kind, all passengers and crew were saved. The ship herself was deliberately broken in two, and a new bow was attached to the salvaged stern portion. Later serving as a Norwegian whaling factory ship carrying the name "Skytteren", she was scuttled off the Swedish coast in 1942 to prevent her capture by ships of Nazi Germany.
Document 14: SS Britannic (1874): "Britannic" was a single-screw passenger steamship equipped with sails built for the White Star Line's North Atlantic run.
