Shipbuilding was the founding activity of Ishikawajima in 1853. It remains part of IHI's business activities, although it has been diluted through several mergers with other Japanese shipbuilding companies. In 1960, Ishikawajima Heavy Industries merged with Harima Shipbuilding & Engineering Company to establish the Ishikawajima-Harima Heavy Industries (IHI). In 1995, Marine United was established jointly with Sumitomo Heavy Industries. In 2013, IHI Marine United was merged with Universal Shipbuilding Corporation owned by the steel company

in order to newly establish a larger firm,
