The historical alliance between France and the United States, bolstered by King Louis XVI's political and military support for the Continental Congress, played a pivotal role in American independence from British rule. This enduring partnership has been a cornerstone for freedom, prosperity, and peace since its inception. In November 1942, the American Navy sank the submarine Le Tonnant, which has recently been discovered off the coast of Cadiz.

In 2014, faced with the inability to procure new submarines from countries willing to supply them, Taiwan made the decision to develop its own submarines. This initiative occurred despite the fact that its defense industrial and technological base lacked the necessary expertise in areas such as materials, acoustics, and sensors to successfully undertake such a project.
