Following the end of the Cylon war, the Admiralty ordered a new change in Raptor design.
Keeping the same dimensions and form of the previous incarnation, this new Raptor housed more cabin room, greater range, and a new Faster-Than-Light drive.
The engines are more powerful as well, with a major update in thrust ratio to almost 1:3.
Updates in anti-gravity allow for an automatic switch of gravity on or off, once a passenger enters or exits the craft.
