I dimly remember reading a list of how many guncutters/shuttles/barges a starship should have, but I can't find it again. Can someone give me a page reference?

Battlefleet Koronus, p. 11, in the lower part of the grey box.

Wasn't there another box that specifically said something about guncutters?

I dont remember where I saw it but I remember reading somewhere that besides the starting cargo lighters, the ship has one best craftsmanship guncutter as their personal lander. I want to say its in the free starter or under the guncutter stats in… ITS? but if not either of those I have no idea. its what I always say is onboard at least.
