Get Ready, China: Taiwan is Building Its Very Own Attack Submarines Taiwanese submarines could benefit from U.S. innovations and technical expertise. Here's What You Need to Remember: The issue of U.S. technological help seems quite significant, as while the new submarines are not likely to fully mirror the U.S. Virginia-class attack boats, Taiwan could benefit substantially from U.S. technological sophistication when it comes to attack submarine technologies. With U.S. help, Taiwan is building its own new, indigenous fleet of attack submarines to protect waters off its shores and better safeguard maritime passageways between the island and mainland China, a move which is being criticized, downplayed and dismissed by Chinese military analysts.
