Some folks complained the 15 years of the Enterprise F was too short, but I'd argue its alot longer then alot of Enterprises got.
The NX Enterprise was decommissioned after just 10 years.
The TOS Enterprise had a damn long run, but is dust now.
Enterprise A only lasted 7-8 years
Enterprise B, unknown.
Enterprise C was destroyed, but I think it had roughly over 20 years, no exact date to its launch.
Enterprise D lasted 8 years.
Enterprise E Unknown, but last seen taking a massive asskicking in Prodigy.
Enterprise F 15 years
Enterprise G unknown
Enterprise J Unknown
and to compare to another big name ship Voyager got decommissioned right after it returned to the Alpha Qaudrant so roughly 7 years.
So 15 years alot more then at least 3 other big name Enterprises at minium and Voyager.
