TYPE 091 / HAN class

The Type 091 or Han class nuclear attack submarines, (SSN), were the first nuclear submarines put in service by the Chinese Navy (PLN) in 1974. Although they were not technologically advanced as their western contemporaries, they were solid enough to be the basis of the following SSN and SSBN Chinese submarine classes. Five submarines were built until 1991, and currently 3 units remains in service. They can fire C-801 / CSS-N-4 Sardine anti-ship missile, although they have to be on the surface for firing, which is a clear tactical disadvantage. It is known that they are quite noisy and emits high radiation levels for the crew, and it is suspected that during their development phase there have been some accidents of nuclear nature that have been hidden for the rest of the world.
