Greetings all, this is my first post. To be correct, I learn that the RoC Navy has got two (2) diesel electric submarines built in the Netherlands in the 1980s. But why not a large fleet of modern submarines? Wouldn't that be an indispesible component in the defense of an island gainst an overwhelming invasion force with air and surface superiority? Also posing a threat to PRC's sea trade routes that could make a protracted sea war very costly. I've heard US military analysts say that they don't think much of PRC's anti sumbarine warfare capabilities. - Is it somehow explained by RoC's military doctrine? - Is it because noone is willing to export submarines to the RoC for diplomatic reasons? - Even if so, couldn't the RoC have developed domestic know how to build their own submarines?
