### Ships[edit]

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.[12]

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 JFE Holdings in order to newly establish a larger firm, Japan Marine United Corporation (JMU), of which IHI remained a shareholder.

In March 2020, Japan Marine United (with 49% of shares) agreed to merge with Imabari Shipbuilding (with 51% of shares) into a joint venture named Nihon Shipyard (NSY), covering all ship types except Liquefied natural gas (LNG) tankers.[13] This agreement became effective in January 2021. In parallel with the creation of Nihon Shipyard, Imabari Shipbuilding bought 30% of JMU's shares, while IHI and JFE Holdings each kept 35% of JMU's capital. The merger between these two Japanese companies resulted in Nihon Shipyard becoming one of the largest marine-engineering and shipbuilding companies in the world, of which IHI remains a shareholder.
