This fitting includes the benefits of the
Atmospheric Configuration fitting, as well as allowing the ship to
operate while immersed in a liquid medium. Submerged ships cannot be
detected with conventional planetary traffic sensors and require
military sonar and naval sensors to fix their position, resources often
unavailable on less developed worlds. So long as the ship stays away
from military naval craft and bases, it is almost impossible to track
while submerged. Only fighter and frigate hull classes can mount this
fitting.
