Thanks. I'm actually going for a 23-24 century hybrid. I'm thinking his was a ship that may have been in the prototype stage around 2290-2320, with production models following shortly thereafter. That still gives the class a good 40-70+ years of "life" before TNG, in case the class didn't still exist by then. But, since we never saw every class that existed, we'll never know what all did and didn't exist by the year 2364.
