Note: Of these 18 planned vessels, four, 531, 532, 550, and 575 are currently still building (October 2012) and it is rumored that 531 and 532 may well be an improved version, the Type 054B. If this is so, then there will be two Type 054s, 16 Type 054As, and the first two of an undetermined number of Type 054Bs. If 531 and 532 remain in the standard Type 054A configuartion, then there will be a total of 18 Type 054As.
