DF26 can reach any large moving targets, 5000 km away!

DF21D covers moving stuff within a radium of up to 3000 km. Note that the former is also equipped with nuke warheads.

Thus, it is hard to think to send an aircraft carrier to the region where it takes risk of loosing several thousands of soldiers' lives when a confrontation takes place.
