Wouldn't they get picked off by F35s? I feel like they would be basically defenceless against F35's with NSMs, unless I'm sorely underestimating PLA's area air defence and networking capabilities
Type 056's air defence is excellent for ships of its weight class. HQ-10 is for self defence and is considered having better performance than the longer range HQ-7. These ships's mission roles are littoral - port and navy base patrol and defence, shallow coastal ASW patrol, escorts for larger capital ships leaving and arriving at ports/bases etc.
This puts their areas of operation behind that of larger ships equiped with area defence missiles, and also linked to the radar and other sensors to DDGs and FFGs, and as well as KG500/KG2000/KG2000 by real time datalink which give type 056 ample early warning of air intrusions near them.
Type 056 acting alone may happen to smaller nations, but China can afford to deploy them as part of 3D deployment, providing mutual supports.
If F-35 is opponent, its target would be the far more valuable ships like aircraft carriers, destroyers and frigates. And these ships also provide area air defence umbrella for type 056.
