Nope. Today's designs are already becoming dated. By the time a new ship could be built, another 5-7 years will have passed. Time to draw up the latest and greatest and get one in the water within hopefully a decade so it's not obsolete in the first five years.
I'm still of the opinion that navies will be obsolete sooner or later unless it's a more advanced country in a war with a third-world country. Space-based and hypersonic weapons will make big ships sitting ducks.
