Monitor
A HM-class Monitor is most often a large spaceship with armament roughly equivalent to a Battleship, often placed in orbit around a mainworld, and used primarily for system defense roles. Generally based on a planetoid hull (...and so automatically unstreamlined), these craft often depend heavily on pre-positioned caches and fuel shuttles.
- They are part of the H-class Defensive Ship grouping.
- Like battle riders, they are in a conquer-or-die situation if facing superior forces. Their deterrent value is therefore fragile as well as powerful. There are a few exceptions to the rule that are equipped with jump drives.
- The Supraclass designation is also known as Ship Mission, Ship Mission Code, Mission, or Ship Hull Designation.
- It is a starship supraclass.

Description (Specifications)
Monitors are usually known as large spaceship with armament equivalent to a battleship, used primarily for system defense roles. Generally based on a planetoid hull (...and so automatically unstreamlined), these craft depend heavily on pre-positioned caches and fuel shuttles. The large size of these craft make them generally impossible to move inter-system. Like battle riders, they are in a conquer-or-die situation if facing superior forces. Their deterrent value is therefore fragile as well as powerful. They are generally viewed as more of a mobile fortress than anything else.

The term of monitor is also used with smaller craft. Any semi-mobile fortification, lacking jump capability may be known as a system monitor, but are often grouped in other classes.
