However after the merger of Cunard with once rival, White Star Line, construction restarted off the back of a British Government subsidy, allowing for the construction of the most beloved liner of the 1930's.
A tribute to everything great about British style and design, Queen Mary went on to serve valiantly in World War 2, transporting hundreds of thousands of troops to the war zone for King and Country.
After providing a war bride service at war's end, Queen Mary was returned to Cunard to enter service alongside her newer fleetmate, Queen Elizabeth.
She served Cunard until 1967, by which time the economies of passenger shipping was devastated by transatlantic Jet aircraft services. Retired to Long Beach in California, Queen Mary remains to this day the greatest example of transatlantic history as a hotel, museum and conference centre.
