The Perilous-class Destroyer is a multipurpose destroyer. It consists of two sections, one of which is a regular, narrow cylinder hull, and the other of which is a large ring that is connected by three pylons, equidistantly spaced, to the main hull, which the ring encircles. The ring section is more massive than the main hull section. The ship carries two squadrons of fighters on external docking points. While this denies them many of the services of a true docking bay, there truly is no space in the design for such a bay.
