Welcome to TEST!
What kinda fast are you looking for? There are 2 3 4 types of fast in SC at the moment and the ships that currenly sit near or on top of the pile in that regard are:
Fast in normal space:
- Drake Herald
- 350R
- M50
- Razor
Fast in Quantum Drive:
- Vanguard
- Starfarer
Fast in atmosphere:
- Depends on atmospheric density, altitude and the drag of your ship so it's hard to compute, however I know my 350R is slower than a Gladius in atmosphere at near-ground level which makes me a sad sad man.
Fast on the ground:
- Nox
EDIT - All subject to change, of course :)
