The strong competitors of international shipping companies are British British-North American Royal Cruise Company, the famous old shipping giant Cunard Company, which owned the most classic and fastest luxury cruise ship "Lusitania" in the world at that time; Germany's new Hamburg-American shipping company is also a strong competitor of the national shipping company. With the support of the German royal family and navy, it competed to build its own new luxury cruise ship "Emperor" after the Titanic accident, becoming the largest ship in the world at that time. The "Emperor" class replaced the "Lusitania" class of Cunard Company and the "Olympic" class of Morgan Company, and became the class with the largest tonnage, the most luxurious facilities and the largest passenger capacity in the world.
France's transatlantic shipping company (CGT) and Germany's Nord-Lloyd are also competitors of international shipping companies, but although their fleets have their own characteristics, their scale is far less than that of international shipping companies.
