If there's one warship designed to go into hostile space, it would be the five parsec range Azhanti High Lightning fleet intruder.
To clarify, most of Imperium Navy warships are closely structured, so that's going to be a bumpy ride if they decide to dip their wick into a gas giant, where things can get shaken loose.
Not helped by possibly floating minefields and lurking stealthed system defence boats.
It's what's termed a calculated risk, keeping up the momentum of an advance.
The scene from 2010 where they are slingshotting around Jupiter comes to mind (I think it was Jupiter): the ship is shaking pretty badly.
