SS Alexandra Doria was sold to Indian breakers and retired on January 1973. While she was en route from Trieste to Alang, India, she exploded, broke in two, and sank just Southwest of Oman, killing 433 people, 331 of them were crewmembers.
Following the end of World War I, many shipping companies were planning to build new liners once they had enough money. Italiano Liners & Crocieres Internazionales decided to build two new liners of over 30,000 gross registered tons for post war service. The first ship was Victoria Graza which was launched in 1926. The second ship was launched in December 1930 at the Ansaldo Shipyard and was christened Alexandra Doria. She was fitted out and made her maiden voyage on December 4, 1930. Her interior was decorated in the Baroque style. She was the largest diesel-engined passenger ship of her time, whereas her sister was equipped with geared steam turbines. The Alexandra Doria was c. 277 meters long and was designed to carry 1,875 passengers.
Her sister operated on the South American service while she ran the North Atlantic service. The Alexandra Doria could reportedly reach New York from Italy in five days at an average speed of 24 knots. In 1932, Italiano Liners & Crocieres Internazionales was forced by Mussolini to merge with other Italian shipping companies to form the Italia Line. Because of this, the funnels of the Alexandra Doria were repainted in Italia Line colours. In 1933, she began to carry out 129-day world cruises after the Wall Street Crash of 1929. She carried many passengers from New York to a number of ports around the world and back to New York in 129 days.
