Lots of stuff like this on social networks, merely highlighting the lack of military culture of these commentators... It is normal to see rust on the hull of a ship that has been deployed for 6 months like the Lincoln. To say the truth, such a long deployment is an achievemet by itself. It needs a capable supply chain to succeed. And I bet the PLAN is taking notice : while certainly the current naval train of the USN is not at the levl it reached at the nd of WW2, it is, in my opinion, not as helpless as some people portray it.
I can't think of any navy capable of deploying a carrier for 6 months (and certainly not our own Charles de Gaulle

), and tthe PLAN is for the moment limited to its own inland sea behind the 1st island barrier.
