In the long run, Navy arguments for the supercarrier prevailed, though not for the reasons originally cited. A relative failure as a strategic nuclear deterrent, the large aircraft carrier would prove invaluable as an element of conventional rapid deployment tactical air forces, requiring neither overflight permissions or overseas basing rights with host nations. Ironically, a successor to the canceled supercarrier, the radical new USS "Forrestal", and later designs, continue in service with the U.S. Navy into the 21st century, forming the core of its offensive striking power.
