Ah, right - it's the Last Unicorn Games USS Aries
rather than a canon ship that I had to juggle when creating my Grand Unified Spreadsheet of starship names and registries. My bad.
The idea of the Oberth
class taking the place of the Monoceros
class in actual Starfleet procurement suffers from an aesthetic shortcoming: Okuda wants the class ship for Oberth
to be NCC-602 while FJ wanted his subclass to start with NCC-601. Neither used a double-zero registry, though, thus eroding our confidence in a truly "blockwise" system of registries. That is, it seems FJ starts out Monoceros
at NCC-601 because the previous class concluded at NCC-600, whereas "block allocation" might more logically result in something like NCC-700 for the Monoceros
That is, unless this "Mk VIIA" scout really isn't all that distinct from the basic "Mk VII" and for that reason doesn't warrant a new registry batch.
