USN has been necking down to as few jets as is reasonable. The Hornet (classic and Super) effectively replaced the F-4, A-7, A-6, KA-6, and F-14. And the Prowler has been replaced by the Hornet based Growler, and the Viking retired without a replacement. USN is buying F-35 so they have a "first day of the war" stealthy jet, but for the foreseeable future there will always be more Super Hornets than F-35s.
