I've ranked the D-7 as being somewhat inferior to the Constitution of the time, mostly because Kirk and co. never seemed to have much trouble dealing with these ships when they met them. I've tried to make some sense of the design as compared to Federation ships, but otherwise haven't gone into all that much detail concerning the history of the design, since we know so little about the period immediately prior to TOS.
