after 10 years of operations seems like China has developed a good carrier based capability
what China needs to work on is eavesdropping, intelligence gathering, situational awareness, code breaking, surveillance, tracking, monitoring and full spectrum of operations capability integrated with the battle group
Warships are great but they also require years and years of experience and knowledge for true operational capability
also more formation sailing far from home seas is something China must practice in next decade
secondly how well can a Chinese aircraft carrier conduct air strikes far from home at long distance, sortie rates/bombs on targets is also central to a carriers offering
