[Warhammer 40k] Spacefighter Size

So, assuming that the scale for 40k intersteller warships is such that a battleship is 10 Kilometers or so long, essentially the scale in the Rouge Trader RPG sourcebooks, how big would a Fury Interceptor or Starhawk Bomber be?

I've seen the figure of 60-80 meter nose-to-tail thrown around, but I have been unable to track down a source on that. On the other hand, Battlefleet Koronus says that an atmospheric craft takes up half the space of a void craft of the same rough type. Given that a Thunderbolt Fighter is ~15m long, this would suggest a Fury to be in the ~30m range. Given that a Fury has nothing comparable to a thunderbolt's wings and so forth, I am pointedly ignoring the square-cube law.

Given the size of 40k warships, it large fighters would make sense, but taking into account the longer time frame of void battles, and the fact that Starfighters and bombers don't appear to mount Titan-grade weaponry, I'm not really sure what would be appropriate.

Thoughts?

Ok here are some stats taken from Lexicanum:

Thunderbolt (atmospheric fighter): 14.2m long

Fury Interceptor (void fighter): 60-70m long, depending on variant

The size of the craft has little to do with the armaments, and more with the fact that it has a crew of 4 and the significant life support and crew space that entails. Then there is the fact that it has massively larger engines. Lex notes a thrust output of 60,000 foot pounds, roughly three times that of an F16.
