The housing (for both Shanghai and Guanzhou hulls) is also different to the current in-service 1130. The new one on the 054B is slightly more streamlined.An interesting little detail I've just noticed. The Type-1130 CIWS on the unit at Huangpu (top image) differs from the one installed on the Jiangnan unit (bottom): the positions of their radar and optical sensors are reversed. Huangpu's unit is the first instance where the optical ball is installed on the left side. All previous Type-1130s (that I've seen) have the optical ball installed on the right side.
Current 1130 for comparison -
