It is not only buildings that have failed during the construction phase. In the 1920s, the White Star Line hired the shipbuilders Harland and Wolff to build the first ocean liner, with the planned name of "Oceanic". However, a dispute between the companies halted the construction, then the Great Depression put an end to it; eventually the portion of the keel already constructed was broken up and used in building the smaller but similar ship, the "MV Britannic". In the 1970s the Hoan Bridge in Milwaukee, Wisconsin was out of use for five years after its construction when the connecting roads were not completed. In the 1980s, during the Iran–Iraq War, Iraqi president Saddam Hussein commissioned the Babylon project. The supergun design by Gerald Bull was never fully constructed after Bull's assassination in March 1990.
