Imperial Virtue-class battlecruiser Nathan Hale-class surveillance vessel Jaguar-class light frigate Tiger-class heavy frigate
The primary for the Nathan Hale is a pure Vance part. The Tiger, Jaguar, and Swift Vengence's primary are mods by me of a "salvaged" Vance part from the USS Thyella.
Love imperial Virtue. Your two nacelle defender points the way towards Ambassador by way of the refit eara, as opposed to the Excelsior evolved Balmung--(also good). You might try a two nacele Stargazer with a secondary hull on the lower pylon.
TYVM! That one has already been done by others (sometimes called the Challenger class). McCaffrey-class light cruiser
I'm sorry, you had a circular dish with a torpedo to either side of it (version I) with a tube to either side of the dish. This deep chest version looks cool too.
I personally prefer the 'pregnant' version of the enlarged Galaxy hull. I also really like the Provisioner class supply/tender.
