The Type 039 submarine (Song-class) is a class of diesel-electric submarines of the People's Liberation Army Navy. The class is the first diesel-electric submarine to be fully developed within China and also the first Chinese diesel-electric submarine to use the modern teardrop hull shape.

The submarine uses a modern teardrop-shaped hull for underwater performance. The hull incorporates four rudders and is propelled by a single propeller.

The main sensor is the medium-frequency sonar mounted in the bow of the submarine, with passive and active modes, which is used for both search and attack.

The primary weapon for the Type 039 is the 533 mm Yu-4 torpedo, a locally produced passive homing 40-knot (74 km/h) torpedo based on the SAET-50 and roughly comparable to the SAET-60. Surface targets may be attacked at up to 15 km.
