Jackill's fandom art adds the Benning, differing minimally from Coventry.
Was Googling something else entirely yesterday, and stumbled onto another Miranda predecessor by from Jackill. This one was called the Vindicator. Whereas Benning seems to have the short hull, like Surya, Vindicator has the extended hull, like Coventry. Both have nacelle pylons that drop straight down, like Coventry's do, but they also both have an angle on the pylon from the profile view, like Surya.
