China has the world’s largest navy, but there are important questions about its ability to contest the United States on a global scale. To do so, China would need more overseas bases than the two it currently has in Djibouti and Cambodia. Similarly, its aircraft carriers cannot sustain high-tempo aviation operations beyond the First Island Chain for an extended period. Developing super-quiet attack submarines would markedly improve China’s ability to conduct blue-water operations. However, to date, China has not fielded submarines that match the technological capabilities of U.S. boats. A careful examination of China’s naval strength shows that while it is well-positioned to wage a war close to its shores, the PLAN is not a global peer of the U.S. Navy.
