China has been working on upgrading its Type 094 (Jin-class) submarines, allowing them to carry the more powerful and longer-range JL-3 ballistic missiles.
China has invested heavily in recent years to make rapid strides in the redesigning and reconfiguration of submarines, making them stealthier and quieter.
The Chinese MBT is expected to have high mobility, stealth and strong strike capabilities and will be operated by two crew instead of the standard three.
