Not really They used over the horizon radar to cue in their their burgeoning space asset to find the CBG then confirm it either with UAV or J20. In this time and age Satellite do most of the work completely different than WW2 carrier engagement where they used spotter plane
There is no place to hide big ship anymore. SM3 is not perfect yet . They are not even finished testing yet and easily fooled by counter measure and MIRV not to mention the violent terminal boost.
whatever test that they did are mostly dumbed down test with no real world relation
The first brigade of DF 21C is already forming as of last year
Last week, China’s state-run media quietly announced the construction of facilities for a new Second Artillery missile brigade – the 96166 Unit – in the northern Guangdong municipality of Shaoguan [韶关]. Although the province is already home to a Second Artillery short-range ballistic missile (SRBM) brigade (the 96169 unit in Meizhou), initial reports and indicators signal that the new unit could have unique capabilities that could complicate the strategic calculus in Asia, and the South China Sea in particular.
Although the introduction of the 1,700km range solid fuelled, terminally guided DF-21C ballistic missile into Guangdong is possible, the brigade is also a candidate to be the first unit equipped with the DF-21D anti-ship ballistic missile (ASBM). The DF-21C, first introduced into the active inventory in 2005, is designed to attack fixed targets on land. If an ASBM is successful in passing the necessary design reviews and a sufficient sensor network is in place, the Shaoguan brigade could become the first in the PLA to field a lethal capability against moving targets at sea out to a range of 1,500-2,000km or more from launch sites.
