Dubei-class target ship

Dubei class target ship (AGT) and range supporting vessel is a very little known auxiliary ship of the People's Liberation Army Navy (PLAN), and has received the NATO reporting name Dubei class. Originally built as a SWATH test platform, it was subsequently converted to a target ship by adding radar reflectors and other electronic equipment to simulate various targets in support of anti-ship weaponry development, but is still capable of housing different scientific instruments to perform various research tasks, and thus also acts as general purpose research ship (AGE). With the exception of the first unit of this class, ships of this class in PLAN service are designated by a combination of two Chinese characters followed by two-digit number.
