A successful ship design lasts half a century and more. But there are also ship designs that were only good for a short period of service. For example, the Invincible-class aircraft carriers were in service from 1980 to 2014. The South Dakota class battleships were only in service from 1942 to 1947.
Remember: nobody knows what aircraft will look like 20 years from now.
