The USS Essex is the only ship definitely known to be a Daedalus class. The Archon and the Horizon are conjectured to be Daedalus class ships in the Chronology, since they are in service at the same time as the Essex. Since the Chronology is a backstage source, I've coded this as green.
The idea that they where mothballed is my own, as is the date for the
introduction of the prime directive - canon only establishes that the PD
was instituted somewhere between 2168 and 2264. I linked the Daedalus class
to the development of phasers as a way to build a bridge between them and
TOS, and put one in the fleet museum alongside the Constitution Picard
mentioned in 'Relics'.
