Its a Hospital ship built out of spare parts. Take a Dreadnought Saucer and dorsal nacelle, mate it with a mobile hospital transport pod, and add a pair of inverted Surya-class frigate nacelles.

They probably won't, so the ship's going to need a fairly heavy escort if she goes anywhere near the Neutral Zones, or, Kami forbid, the Triangle... 'cause you know doggone good and well that the Orion Syndicate won't respect medical symbology.
Cue Federation-class dreadnought lighting up the Orion DN with it's targeting sensors. Federation-class Dreadnought Captain: "You shoot that hospital ship, I will fry you. Get the picture, moron?"
And pray the Klingons and Romulans respect the Red Cross.
