Top navies like China, the US, and in the future, India will build typical supercarriers. Some tasks, such as the EAW, REC, and tanker, will be taken over by UAVs. Somewhere in the second tier will be the UK, France, Japan, and Korea, which will operate smaller vessels equivalent in size to the QE2 or ChdG. Other navies will attempt to build purely UAVs and aircraft carriers, but this won't be successful for a long time.
