The Chungsŏng class is a class of nuclear-powered attack submarine designed and built in Menghe during the 1990s and 2000s. There are three major subclasses, known in the West as Chungsŏng-I, Chungsŏng-II, and Chungsŏng-III. With a teardrop hull, a streamlined sail, and a variable-depth sonar pod, they represented a major development leap over the preceding JW-351 class. Menghean news sources also claimed that the Chungsŏng-class had achieved a very high level of acoustic quieting, on par with contemporary nuclear submarines. In reality, while stealthier than the noisy JW-351s, the Chungsŏng-class submarines were still judged insufficient by the Navy, which ordered the development of a more advanced replacement class.
