New Chinese Catamaran Spy Ship Learns All About Japanese Water
By Jeffrey Lin and P.W. Singer  October 9, 2014

This Chinese catamaran ocean surveillance and research ship, numbered "232", was intercepted by a Japanese P-3C Orion on September 27, roughly 260 kilometers northwest of Okinawa Island.

The white A Frame at the end of the rear deck on the "232" catamaran is likely to be used in winching up submersibles and buoys equipped with oceangraphic survey equipment to measure sea water qualities like salinity, temperature and map the ocean floor. Some of the covered up equipment on the rear deck are also likely to be related to ocean survey; the space between the catamaran's hull is likely to house additional survey equipment.


This catamaran, "429", is apparently the first of the class of spy ships that the "232" also belongs to. 429 was first launched in 2011, around the time that several other Chinese ASW systems like the Y-8Q patrol aircraft and towed array sonars for the Type 056 corvette, were also gestating.
