• They are not considered economical to operate except in very specialized roles.
• Several smaller ships can usually do a better job and are more flexible.

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 - 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 tons - 2,400 tons	Merchant Escort Mercenary Cruiser	Adventure Class ships are usually jump-capable. Naval parlance may use the term Auxiliary Class Ships They serve many roles including customs, patrol, planetary defense, tramp freighters, etc. Large Adventure Class (Large ACS): 1000 ton - 2400 ton Small Adventure Class (Small ACS): 100 ton - 1000 ton
4.	Battle Class Ships (BCS)	2,500 tons - 250 ktons	Cruiser Bulk Trader Battleship Sleeper Ship	Battle Class ships are warships. They are usually jump-capable. Civilian corporate concerns may use the term Bulk Class Ships Such ships require major investment and only service major roles including megacorporate interstellar trade, warships, Capital Ships, and major endeavors. Capital Class (CCS / Very Large BCS): 100kton - 250kton Large Battle Class (Large BCS): 25kton - 100kton Small Battle Class (Small BCS): 2kton - 25kton
5.	Fleet Class Ships (FCS)	250 ktons - 1 Mton	Fleet Battlerider Carrier Dreadnought	Fleet Class ships are primary warships. They are usually jump-capable. Such ships require major investment and only service major roles including major megacorporate interstellar trade and capital projects, Heavy Capital Warships, and other similar major endeavors.
6.	World Class Ships (WCS)	> 1 Mton	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)

The size of what is considered gigantic or World-class changes every few tech epochs. What was once mighty and large eventually is regarded as less impressive as technology advances.
