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	Class	Commonality	Remarks
1.	Smallcraft (Subcraft)	0 to 99 tons	Vehicle	Ubiquitous	Smallcraft are NAFAL or STL. Smallcraft are typically designed to be carried by larger carrier craft. Such vehicles are called Subcraft. This class represents Shuttles, Gigs, Fighters, etc.
2.	Bigcraft (Subcraft)	100 tons or larger	Vehicle or Ship	Uncommon	Bigcraft may be designed FTL or NAFAL. Bigcraft are designed to be carried by larger carrier craft as Subcraft. This class represents SDB's and ship-sized subcraft.
3.	Adventure Class Ships (ACS)	100 to 2,499 tons	Ship or Vessel	Common	Adventure Class ships may be FTL or NAFAL. They are typically designed FTL and service many lesser roles including customs, planetary defense, tramp freighters, etc. This class represents Merchants, Escorts, etc.
4.	Battle Class Ships (BCS)	2,500 to 249,999 tons	Ship or Vessel	Uncommon	Battle Class ships may be FTL or NAFAL. Such ships require major investment and only service major roles including megacorporate interstellar trade, warships of capital class, and major endeavors. This class represents Cruisers, Bulk Traders, Battleships, etc.
5.	Fleet Class Ships (FCS)	250,000 to 249,999,999 tons	Ship or Vessel	Rare	Fleet Class ships may be FTL or NAFAL. Such ships are tremendously expensive and represent polity-level investment in RU's. This class represents Dreadnoughts, Superweapons, large Sleeper Ships, large Generation Ships, etc.
6.	World Class Ships (WCS)	2,500,000 tons or larger	Ship or Vessel	Ultra-rare	World Class ships may be FTL or NAFAL. Such ships are beyond expensive and represent suprapolity-level investment in many RU's. This class represents World-Ships, Super Dreadnoughts, Superweapons, etc.

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.
