Obviously "Enterprise" is pretty much synonymous with "Star Trek", so new shows and movies will continue to have an Enterprise.
However, in-universe, how many times does a ship of a given name need to be blown up before it would be considered unlucky? Alternately, hasn't at least one of the previous Enterprises been destroyed in such a manner as to merit an honorary retirement of the name?
Is there an in-universe reason that Starfleet didn't retire the name "Enterprise" after its predecessors suffered less than ideal fates?
