Battle Class Ships (BCS) are starships and spacecraft not suitable for use by groups of small groups of adventurers or operatives.

• Battle Class Ships are 2,500.0 tons or larger and are created using the BCS Design System. BCS ships operate in fleets and squadrons and include some small ships only where necessary.
• They require large crews, major investments of fuel and supplies, and large-scale logistics support. Only megacorporations or major polities can afford to operate such large freighters and warships.
• The ships are parts of very large operations, carry enormously profitable cargos, and are parts of very large naval movements. The activities of the individuals matter little on such as scale.

Description (Specifications)

Tonnages: Battle Class Ships are built using standard hulls 2500.0 tons or larger.

• Vessels smaller than 100.0 tons are Small Craft. Adventure Class Ships (ACS) weigh in between 100.0 tons and 2499.0 tons displacement.

Naval Ship Synopsis by Size-Role

These vary in tonnage and in their intended function or role in fleet maneuvers and tactics. The security of the state is usually the primary design imperative.

Ship Classification by Size
#	Type	Tonnage	Examples	Remarks
1.	Smallcraft	0 to 99 tons	Shuttle Gig Fighter	Smallcraft are typically Subcraft, designed to be carried by carrier craft.
2.	Spacecraft	100 tons or larger	SDB Rider Monitor	Spacecraft are in-system vessels, lacking interstellar drives. Some Spacecraft are Subcraft, designed to be carried by carrier craft.
3.	Adventure Class Ships (ACS)	100 to 2,499 tons	Merchant Escort Mercenary Cruiser	Adventure Class ships are usually jump-capable. They serve many roles including customs, patrol, planetary defense, tramp freighters, etc.
4.	Battle Class Ships (BCS)	2,500 to about 1,000,000 tons	Cruiser Bulk Trader Battleship Sleeper Ship	Battle Class ships are warships. They are usually jump-capable. Such ships require major investment and only service major roles including megacorporate interstellar trade, warships, Capital Ships, and major endeavors.
5.	World Class Ships (WCS)	Larger than 1,000,000 tons	Loeskalth planetoid generation ship.	World Class ships are beyond expensive and represent suprapolity-level investment. They take many years to build. This class represents immense World-Ships, very large Super Dreadnoughts, Superweapons, etc. Operational staff are typically residents as much as crew. These ships are interacted with as worlds or events, rather than ships.

History & Background (Dossier)

Battle Class Ships are far less numerous than the smaller Adventure Class ships, and each and every one of them is a significant investment made by an interstellar player within Charted Space. Since they are always major pieces on the game board of Charted Space (…not pawns), they are always guarded, watched, accounted for, and otherwise tracked by significant entities. Their enormous roles in keeping the greater interstellar civilization alive and prosperous are vital.

These vessels are typically operated on behalf of the central government. They are typically not available for private ownership. These are vessels found in planetary navies, subsector fleets, colonial and reserve fleets and sector fleets. They are typically organized into squadrons and grouped by function.
