The Type 648 repair ship is a Chinese submarine repair ship currently in service with the People's Liberation Army Navy (PLAN). It was one of the two units consisting the proposed mobile repair flotilla, but the floating dry dock with lifting capacity of 2000 tons was never built, and Type 648 repair ship was the one only completed.

The Type 648 is designed by the 3rd Directorate of the 708th Institute of China State Shipbuilding Corporation (CSSC), which is also more commonly known as China Shipbuilding and Oceanic Engineering Design Academy (中国船舶及海洋工程设计研究) nowadays, after receiving the assignment from PLAN in October 1975. Construction begun in July 1980 and completed in December 1984, and the ship was formally handed over to PLAN in January 1985 with name as Dong-Xiu (东修, meaning East Repair in Chinese) 911.
