Hey, there is not much love for the Vesta class on memory beta etc so for those, like myself, who like this ship class I found these images on the blog of Mark Rademaker (here: http://mark-rademaker.blogspot.com/). Hope you enjoy, they are quite large images of the Vesta class Aventine.
The Vesta Class has really grown on me over time. It has a sleek, swept-back look to it that evokes, on some levels, aquatic life. Especially with its black detailing, to me that ship is the shark of Starfleet. It looks like a proper progression or evolution of the classic Starfleet design. On top of all that, it's currently playing a major role in the Star Trek novel series, and I like to see all my Trek connected! I'm really looking forward to seeing this ship in-game.
