BITS – Ships

BITS – the roleplaying game system – is all about themes. Carrying off of last week’s theme of groups in BITS, I’ve been able to think awhile on how different kinds of actors in BITS work together.

So today: How ship-sized vehicles in space and on the water interact with each other.

How Ships Work

Ships have a threat tier that indicates their size:

0 – Fighters, boats.
1 – Corvettes, frigates.
2 – Destroyers, cruisers.
3 – Battleships, carriers.
4 – Dreadnoughts, city-ships.

When acting as a ship, add the ship’s tier to a 2D6 roll (or appropriate BITS value, if so inclined!). When acting against a ship, roll higher than that ship’s threat tier. For example, a tier 3 battleship acting against a tier 2 destroyer must roll 9 or more (threat tier 2) with 2D6 and may add 3 to the roll.

Tiers also show how many extra smaller actions the ship may take. These smaller actions may be either defensive or of more minor consequence. (I’m still ironing out the value of different kinds of actions.)

A ship may hold inside it smaller ships that are 2 threat tiers below it, and/or multiple groups of ships 3 or more tiers below. For example, a tier 3 carrier may hold 1 tier 1 corvette and/or multiple groups of tier 0 fighters.

A ship otherwise behaves as any other fictional Being in BITS. (This includes the use of Body as a hull and engine, Interaction as a sensory and communications capability, Thought as targeting and computation, and Specialty for whatever role the ship is fitted out to do!)

Tier Examples

Tier 0 fighters and boats exist only as groups when interacting with higher-tier ships. Tier 0 can be subdivided into interceptors, bombers, dropships, and others. Subdivisions of tier 0 ships are differentiated with simple rules.

For example, a Star Wars X-Wing would be a heavy fighter with critical roles against single ships automatically destroys the other ship (representing a proton torpedo exploding). A Gundam Ball is incredibly cheap, but cannot travel without a carrier though is useful for ship repair. A Chinook helicopter serving with the United States Navy is slow, but can carry supplies, a platoon of troops, or gunship weapons.

Tier 1 ships include dedicated troop carriers, freighters, and smaller warships. Individual capabilities are defined per ship, such as being able to travel between worlds or systems.

For example, the Star Wars Millennium Falcon is a very fast cargo freighter. Expanse‘s Rocinante packs freight, troops, and torpedoes with high maneuverability (and fits into the Donnager tier 3 battleship!).

Tier 2 destroyers and cruisers can carry a boat or small fighter group to support operations. Ships called “cruisers” (Star Trek Romulan D’deridex) and “destroyers” (Star Wars Star Destroyer) are often tier 3 battleships and carriers in their abilities.

For example, a USN destroyer may have a vulcan cannon to have advantage defending against missiles and fighters while having a mine-laying helicopter. Star Trek Galor cruisers have a large forward cannon, multiple weapon arrays, and high speed, but can be taken out by swarms of fighters or beefier battleships.

Tier 3 represents the battleships, carriers, and hybrids that bring the largest hurt and the largest number of forces to play.

For example, the Imperial Japan Yamamoto battleship had defensive and offensive advantage against any other ship on the water. The Star Wars Star Destroyer could field squadrons of tier 0 TIE fighters, capture a tier 1 Tantive IV blockade runner, land an army of troops and supplies, and bring massive guns to bare. Many Star Trek variants of the Enterprise flagship were on-par with battleships, fielding multiple torpedo launchers, heavy shields and armor, and even fighters and personnel shuttles.

Tier 4 ships are awe-inspiring, all-commanding giants. For the most part unassailable, tier 4 ships get to do what they want to do until a lucky action halts their progress.

For example, Star Wars has the Executor dreadnought that only by a lucky suicide and very poor design was brought down. The Expanse has the literal Behemoth city-/generation-/flag-ship capable of holding a fleet inside it. Star Trek brings to mind Borg Cubes that single-handedly can wipe out armadas. Even the universe of Frank Herbert’s Dune has Heighliners as the only mega-vehicles capable of interstellar travel, taking entire planetary populations from place to place.

Bonus Topic: Stations

Space stations or naval dockyards work the same way as the ships they house. Stations use similar groupings:

0 – Buoy, small communications satellite, mine, sounding station.
1 – A station with limited docking and housing capabilities. The International Space Station.
2 – A regional yard or asteroid base. Halo‘s orbital defense platforms can handle cruiser-sized craft but none larger.
3 – A strategic hub of resupply and production of battleship-tier craft. Deep Space 9 from Star Trek caters to multiple battleships and support vessels. Stargate Atlantis has Atlantis, which may count as a tier 4 station (there’s some techno-magic that makes classification fuzzy).
4 – A massive complex meant to be bringing forth armadas and entire fleets. Star Trek‘s Spacedock 1, Halo‘s High Charity, USN Norfolk Base.

A station may hold ships that have the same threat tier or below whether constructing or docking the ship. The station may or may not have defensive or offensive means. If so, the station uses its threat tier for resolutions.

For example, a tier 0 listening post may detect ships approaching a tier 1 science station orbiting a moon. Tier 2 defense platforms may open fire and release a compliment of fighters so that a tier 3 space dock can muster battleships and carriers to fight. When all else fails, a distress signal summons reinforcements from the fleet HQ, a tier 4 mega-station.

Thought Behind Design

Inspired by shows like The Expanse and of course movies like Star Wars, I began to see patterns in how the large vehicles known as “ship” were treated in fiction (a class their own; another post later about vehicles later).

After experimenting with carriers (ships carrying smaller ships) and threat tiers, I am struck by how tightly the BITS treatment of ships above fits into naval considerations. From the real-world United States Navy, to modern space flight, to hard sci-fi in The Expanse, to the fantasies of Star Trek and Star Wars, a 0 to 4 threat tier system where some ships carry other ships seems to work really, really well!

So that’s the thought behind: Keep with the mechanics found throughout BITS, allow for all the classic naval designations, and thematically represent ships regardless of “universe” or IP they exist in.

Ready to play some BITS? I know I am 😁

Now to get these manuals taken care of and updated to 2021 standards!

What do you suggest for putting rulebooks together? What holes are there to sink this handling of ships? Let me know! Cheers to your gameplay ~
