Here's an article about CVN-80 being named Enterprise:
Every Trek fan will be happy for this! We've had the old Enterprise in service for the entirety of the franchise history until now; it would be tragic not to have a ship named Enterprise around - or at least planned to be around.
Now, while the CVN-80 Enterprise won't be commissioned until 2025-2027, keep in mind that the hull is designed to be in service for a whopping 50 years MINIMUM - for comparison, the previous Enterprise was designed for 25 years and more than doubled it. Our next Enterprise will be with us for a good long time!
