Achilles is a strange looking ship (the kind I like most), the name is what strikes me as odd. It obviously refers to the person, but it brings 'Achilles Heel' to mind, too. The Achilles is also the least S31-style ship in Trek, they are not likely to use powerful warship class's.
Khmmm, I quite like the name tbh Achilles was bad-arse, even if he did have a weakness
Honestly, i don't see what's wrong with the current model. It seems very federation, something like a replacement for whatever sat just below a miranda. *ducks to dodge onslaught of monsoon bashing posts*
