Well, here we are. A fan favourite given the bmused55 MSD treatment.
This class of ship has been a bit of a mystery since we saw it back in 1994 in the TNG finale.
The generally accepted height is around 125 metres which divided by the average deck height of 4m (which includes all the bits and bobs above the ceiling and below the floor) means this beast has 29-31 decks allowing for some uninhabitable space here and there.
The reason for all the shuttles is to enable mass medical evacuations in situations where transporters cannot be used for whatever reason.
Large core to generate ample power for all the medical labs, bio beds and operating theatres, as well as the many transporters aboard. Although only a handfull will be pictured, I could imagine this ship having a dozen personel transporters and at least a dozen medical transporters with extra large platforms to accomodate several antigrav stretchers.
The cluster of sickbay type layouts immediately forwards of a large transporter and the shuttle bay are what I envision as the initial triage centers when the ship is involved in disaster recovery, etc. Just forward of these are some intensive care suites and operating theatres for quick processing of incoming patients. In the neck and aft sections of the sphere are care wards and isolation units for patients once processed through triage.
Crew quarters and evacuee / walking-wounded accomodation is in the primary hull only, so as to keep the secondary hull free for expansion of facilities as each situation requires. Essentially, the secondary hull consists of large empty halls with replicators and holo emitters. With a press of a button, X ammount of the halls can be sickbays, operating theatres or accomodation by replication of materials or holograms.
I’ve hidden several easter eggs in this one. Enjoy
