Hull thickness & Pressure

This is loosely connected with the hull thickness debate:

Assuming an armour 40 hull, how much external pressure can the hull take?

A favourite technique of system defense boats is to sit in a gas giants
upper atmosphere, or underwater on the planet. Just how deep into
each medium can a typically armoured vessel go?
