Changcheng 279 is a Type 033 submarine of the People's Liberation Army Navy.

Development and design

Complete domestic production in China was achieved in 1967, and subsequently the project was renamed the Type 033. However, experience from deployment of completed boats in warmer climates proved that the original Soviet refrigeration and air conditioning system designed for subarctic and arctic area was woefully inadequate for subtropical and tropical regions, so redesigns were needed to improve refrigeration and air conditioning systems, and all boats to be stationed in tropical and subtropical regions went through such a refit. In September 1969 construction of new Type 033s, with improved air conditioning and refrigeration capability, began at Huangpu Shipyard in Guangzhou, eventually, 13 units were completed.^[1]

Construction and career

She launched in 1980s and commissioned in 1980 into the East Sea Fleet.

Changzheng 279 was decommissioned in 2003 and serve as a museum ship in the port of Liugong Island, Shandong. After being converted into a museum, she is painted with a big 279 number on the shell.^[2]
