The U.S. Strike Group retires and cedes the South China Sea or at least the part within range of the PLAAF to the PLAN, until the USAF repositions and four more carrier Strike Groups arrive, in addition to a MEU or two to take those Chinese held atolls.
The Chinese rule the seas for 14-21 days, and then we begin the roll back, sinking every PLAAN ship that can't make it 200 miles up an inland river and flaming their aircraft out of the skies.
That's our capability. Our will, with Zero at the helm, is another matter.
I’ll add to that somewhat.
The US CSGs are used to provide defensive aircover over the patrol boxes of two Ohio-class SSGNs and a couple/few Los Angeles class SSNs with VLS. Which puts somewhere around 300 Tomahawk missilein range of all sorts of ChiCom infrastructure.
A wing of F-22s from Elmendorf or Holloman deploy to Guam or Japan and using inflight refueling conduct offensive fighter sweeps ... killing anything that the ChiComs put out over water. Making the Great Marianas Turkey Shoot look like a well-contested air battle.
We use B-2s with those neat (if old) CAPTOR mines based on the Mk.82 series to mine the living hell out of the approaches to ChiCom harbors.
I could go on and on here ...
