Despite this, she was not a commercial success and relied partly on government subsidy to operate.[8] During service as the flagship of the CGT, she made 139 westbound transatlantic crossings from her home port of Le Havre to New York. Normandie held the Blue Riband for the fastest transatlantic crossing at several points during her service career, during which the RMS Queen Mary was her main rival.
During World War II, Normandie was seized by U.S. authorities at New York and renamed USS Lafayette. In 1942, the liner caught fire while being converted to a troopship, capsized onto her port side and came to rest on the mud of the Hudson River at Pier 88, the site of the current New York Passenger Ship Terminal. Although salvaged at great expense, restoration was deemed too costly and she was scrapped in October 1946.[9]
