 In 2012, another Type 909A with pennant number 893 entered PLAN service, and it is rumored its name is Zu Chongzhi by many Chinese internet claims, but this has yet to be confirmed by official or independent sources.The most distinct difference between Type 909A and its predecessor Type 909 becomes visually identifiable since this ship, with new ships has a raised bow breakwater to reduce water over the bow and a never-before-seen 30-foot-tall, 3-foot-diameter satellite communications antenna on the forecastle.The ship has an enclosed foremast instead of the latticework mast structures found on prior vessels.
