Type 52c Destroyer
Propulsion: Ukranian and German
The first two ships' propulsion is in the form of CODOG, consisting of two Ukraine-made DA80/DN80 gas turbines each rated at ~32,600 hp(24 MW) and two Shaanxi diesel engines (Chinese licensed production of the MTU 20V956TB92 (German)) each rated at ~6,700 hp (5 MW). The DA80/DN80 gas turbine is the export version of UGT-25000 of Ukrainian Zorya-Mashprocket State State Enterprise Gas Turbine Research & Production Complex, purchased by China in the late 1990s as part of license-production in China. [1]The UGT25000 has power rating of 25-27MW depending on configuration [2], but could only provide 24MW upon delivery because development was not fully completed when they were sold to China. A total of eight units were originally purchased and Chinese sources have claimed that all had been upgraded, mainly in the area of turbine blade production techniques, and such update had greatly increased reliability and maintainability.
