Naval Ship Synopsis by Size-Role

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.
