World Class Ships are monstrously large hulls requiring major outlays of resources and requiring years or decades to construct.

• 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.

Description (Specifications)

World Class Ships are absolutely massive, much bigger than the capital ships or fleet class ships are are regularly constructed. WCS'es are almost never produced in large numbers and are often built as custom one-offs.

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 in TL:13-15
#	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 are designed for NAFAL capabilities, but some mistakenly call them FTL. Modern Bigcraft are generally designed to be carried by larger carrier craft as Subcraft. This class represents SDB's, Riders, and ship-sized subcraft including really large craft called fighters. Bigcraft do not mount jump drives. If they mount jump drives, they are called largecraft.
3.	Largecraft (Non-subcraft)	100 tons or larger	Vehicle or Ship	Uncommon	Largecraft are designed FTL. Largecraft are NOT designed to be carried by larger carrier craft as Subcraft. This class represents regular ships and overlaps with many other ship organizational categories. Largecraft mount jump drives. If they lack jump drives, they are called bigcraft.
4.	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.
5.	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.
6.	Fleet Class Ships (FCS)	250,000 to 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 Super Dreadnoughts, Superweapons, large Sleeper Ships, large Generation Ships, etc. These vessels are also known as Capital Ships.
7.	World Class Ships (WCS)	1,000,000 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. They take many years to build under ordinary circumstances. This class represents immense World-Ships, very large Super Dreadnoughts, Superweapons, etc.

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.
