Mitsubishi Heavy Industries (MHI)

Following the post-WWII dissolution of the Mitsubishi zaibatsu, Mitsubishi Heavy Industries was split in January 1950 into three regional companies: West Japan Heavy Industries (Nagasaki), Central Japan Heavy Industries (Kobe), and East Japan Heavy Industries (Yokohama). These were renamed in 1952 to Mitsubishi Shipbuilding & Engineering, Shin-Mitsubishi Jukogyo, and Mitsubishi Nippon Heavy Industries respectively. In 1964, the three were re-merged (into Shin-Mitsubishi Jukogyo, which took the Mitsubishi Heavy Industries name) to reform the modern Mitsubishi Heavy Industries, Ltd. -- the entity now responsible for Japan's H-II/H3 launch vehicle production and F-2/F-35 final assembly. Modeled as a same-lineage identity change on the existing MHI org row; the three intermediate 1950-1964 companies are not separately modeled.

Post-WWII Allied occupation zaibatsu-dissolution policy forced MHI to split into West Japan Heavy Industries (later Mitsubishi Shipbuilding & Engineering), Central Japan Heavy Industries (later Shin-Mitsubishi Jukogyo - continuing entity), and East Japan Heavy Industries (later Mitsubishi Nippon Heavy Industries). All three renamed 1952-05-07.
