World Navies Today: Chinese Scientific, Research and Experimental Vessels

Revised 23 October 2001
Version 1.02
Compiled and Maintained by: Andrew Toppan
World Navies Today Main Page: http://www.hazegray.org/worldnav/

This list includes all known scientific, research and experimental ships over 500 tons displacement, including non-naval craft.

Ships not yet commissioned, or in long-term overhaul/conversion, are listed in [brackets]. Navigation and surface-search radars are not listed. All classifications are purely unofficial and are based on an attempt to use standard classifications throughout all navies; they may or may not correspond to "official" designations.

Note: It remains very difficult to obtain accurate, up-to-date information regarding Chinese naval forces. These is major conflict between published references, especially with regard to class names and numbers. It is also difficult to tell exactly how many vessels are active and how many are in reserve, since many "active" vessels only go to sea for a few days each year. This list represents the best data available from a variety of sources, however, it probably is not complete nor 100% accurate, due to inadequacies of source material.

Fleets: The following abbreviations are used to indicate fleet assignments:
YEL: Yellow Sea. Officially North Sea Fleet.
ECS: East China Sea. Officially East Sea Fleet.
SCS: South China Sea. Officially South Sea Fleet.
