Was Vickers a Mitsubishi Heavy Industries subsidiary?
Short answerNo. Vickers had a strategic partnership with Mitsubishi predecessor organisations, dated here to 1905.
NotesThe relationship was a strategic partnership rather than subsidiary ownership. It is dated to 1905 with Mitsubishi predecessor organisations. The modern corporate form did not exist for that whole period, with incorporation dated here to 1950. The partnership is said to continue until Vickers ended.
