China Navy renovated the frigate that was obsolete, fire support ship equipped with Tarenso rockets instead of anti-ship missile will be or have been enrolled

So they've done the common sense thing and simply taken an old frigate, added MLRS pods to it and re-designated it a fire support ship.  The only real issue (because I think its a great idea) is re-arming it at sea.  Against a proper target it could expend its "ready to fire" load in a few minutes.
