The
Cardenas-class is a pre-TOS ship. Lorca's command before
Discovery was the
Cardenas-class USS
Buran. It predates the
Constellation-class. I'm fine with the
Stargazer NCC-82893 being
Sagan-class; it's the pre-
Constellation Stargazer I'm curious about.
Don't get me wrong, I
love the old-school simplified TOS style of the
Radiant-class... I mean, just look at it, it's superb!...
...But as
Discovery already introduced a mid-23rd Century four-nacelled ship I'm just curious as to why they didn't make a previous
Stargazer one, especially as it would have given them the opportunity to add a new tie between
Picard and
Discovery.
