Following the humiliating Opium War of the mid-19th century, China faced continual encroachment from Western nations, and total defeat at the hands of the “upstart” Japanese in 1895. The occupation of Beijing by an alliance of powers in 1900 only added insult to injury. China’s profound maritime weakness, however, encouraged surprisingly bold thinking about emerging technologies for undersea warfare. Over the last decades of the 19th century, Chinese leaders attempted vainly to gain the support of foreign powers, particularly Britain and France, for constructing a modern navy. In 1915, a former U.S. naval attaché, CDR Irvin Gillis, arranged for the visit of Vice-Admiral Wei Han and 30 Chinese student officers to Groton, Connecticut to observe submarine building and operations. According to one account, Wei Han “delighted [Electric Boat] officials by announcing that China needed a fleet of 200 submarines.” An initial purchase of 12 vessels was inked, and plans for training Chinese crews were put into place. Unfortunately for China’s navy – and for Electric Boat – these agreements collapsed as the imperial regime gradually gave way to the so-called warlord era.
