Development and design

Main article: Romeo-class submarine

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]
