Re: The Valiant never seen....
is essentially a fast relativistic ship design adapted to having a space warp drive setup fitted to it. Hence the pointed nose for a ship that can accelerate to near light speed. At those speeds you quickly learn that space is hardly empty vacuum at all. You therefore need such a shape to help cleave through the interstellar medium much as a jet aircraft has a pointed nose.
