I've flown down a tunnel that I made inside a giant cube, with no drop in frame rate at all. I put a Cain inside the large room at the end, called it 'Reactor' and made a sexp that when it was destroyed, a few seconds later the Cube would also go BANG.

So no drop in frame rate at all - I spose that if the ship was more complex it would happen, but I dunno.

I meant that if you'd use poly-counts so that your average amount of visible polies is comparable to a game that was made with indoor graphics in mind, you'd have a much worse frame-rate.

Keep it simple, use clever textures and it might be OK.
Perhaps bumpmapping could help if we can get that in.

The idea is that the ship is so impossibly HUGE that when you come to the 'Tunnel Run' you're so close to the ship that you can't see 99% of it! The idea is a wall of ship with turrets and some shape and texturing to it - you blow off a hatch cover, fly in, destroy the cooling systems, then get out before the ship goes nova.
