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.

  • Description (Specifications)[edit]

    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.

    Strategy & Tactics (Doctrine)[edit]

    Monitors most often operate according to predetermined plans designed to optimize their defensive potential. They are typically stationed at the vital points of a system including gas giants, asteroid belts, mainworlds, and so on. Because they usually have no jump drives, shifting them from system to system can be a problem. Some types have jump shuttles which fit to the craft and provide jump capability. Another method is simple transport in large bulk cargo containers or on ship transporters; the monitors are loaded into many-thousand-ton transports or bulk carriers for the multi-parsec journey. This method, of course, is not recommended if immediate combat is expected at the destination.

    Supraclass Roles[edit]

    Monitors typically serve the following roles:
    Largecraft, Smallcraft & Bigcraft:

    LHM-class Monitor Supraclass Archetypes
    Archetype Type Code
    Asteroid Monitor (HMP)
    Buffered Asteroid Monitor (HMP)
    Heavy Asteroid Monitor (HMP)
    Heavy Monitor (HMH)
    Light Monitor (HML)
    Medium Asteroid Monitor (HMP)
    Medium Monitor (HMM)

    Superheavy Monitor (HMS)
    System Defense Monitor (HM)
    System Monitor (HM)
    Ultraheavy Monitor (HMU)
    Very Light Monitor (HMVL)

    Size-Class Roles for Cruiser Vessels[edit]

    1. Utility Craft (U) (1 to 99 tons)
    2. Very Light Monitor (HMVL) (100 to 2,499 tons)
    3. Light Monitor (HML) (2,500 to 99,999 tons)
    4. Medium Monitor (HMM) (100,000 to 249,999 tons)
    5. Heavy Monitor (HMH) (250,000 to 499,999 tons)
    6. Superheavy Monitor (HMS) (500,000 to 999,999 tons)
    7. Ultraheavy Monitor (HMU) (1,000,000 or more tons)

    Military Subcraft[edit]

    Military subcraft (...both smallcraft and bigcraft) are carried by some of these vessels:

    1. Battle Rider (BR)
    2. Combat Barge (WBG)
    3. Combat Transport Smallcraft (UI)
    4. Fighters (F)
    5. Militarized Utility Craft (UQ)

    Supraclass Archtypes[edit]

    HM-class Monitor Supraclass Archtypes
    Archtype Type Code/s Exemplar Remarks
    Monitor HM Vishe class Light Monitor 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.

    • H = Defense & Security
    • M = Monitor
    Heavy Monitor HMH None. None. (250,000 to 499,999 tons)
    • H = Heavy
    Light Monitor HML MacHeany class Monitor None. (2,500 to 99,999 tons)
    • L = Light
    Medium Monitor HMM MacHeany class Monitor None. (100,000 to 249,999 tons)
    • M = Medium
    Planetoid Monitor HMP Empress Troyhune class Planetoid Monitor None. Planetoid Hull
    • P = Planetoid
    Superheavy Monitor HMS Methuselah class System Defense Monitor None. (500,000 to 999,999 tons)
    • S = Superheavy
    Very Light Monitor HMVL Vishe class Light Monitor None. (100 to 2,499 tons)
    • VL = Very Light
    NOTES: There is semantic overlap between many of the classes and codes. Some codes organize by mission or capability, others by size and tonnage, and yet others by other characteristics.

    History & Background (Dossier)[edit]

    Hull-P-Planetoid-THUMB-T5-Core-Rules 01-June-2019b.jpg

    Monitors are among the oldest spacecraft or large boats found within Charted Space. They are the larger big brother of the more ubiquitous System Defense Boat. While many are purpose built, it is not uncommon to take older hulls, remove the antique jump drive, and convert out-of-date, obselete battleships and cruisers into monitors. In many but not all such cases, a substantial cost savings can be realized. At any rate, there a vast array of monitors of various types and makes both manufactured, re-manufactured, and operated within Charted Space. This AAB Library Data file only contains a selection of available hulls. [1]
