 Nearly one and half a decades after the first Type 909 entered service, a successor Type 909A entered PLAN service as Hua Luogeng.Currently, assignments are split between two ships, with Bi Sheng (# 891) tasked to conduct trials for missiles launched from container/launcher, while Hua Luogeng (#892) tasked to test all missiles that are vertically launched from vertical launching systems.However, it must be said that such division of work is only due to administrative purposes, not technical limitations, as both ships are capable of conducting trials for both vertically launched missiles and non vertically launched.
