Description (Specifications)

There are two factors that set bigcraft aside from smallcraft or starcraft:

1. Bigcraft differ from smallcraft in that they are larger. Smallcraft cap out at 99.99 tons. Bigcraft are a hundred or more tons in size. Bigcraft could theoretically be equipped with a jump drive.
   1. Bigcraft may be very large fighters, attack boats, or battle riders and thus also be subcraft.
2. Bigcraft differ from starcraft in that they are not equipped with a FTL Jump Drive. Bigcraft are system craft, meant for intraplanetary travel, not trans or interplanetary travel between stars and star systems. Starcraft travel between stars. Bigcraft or spacecraft, in the pure sense, are not.
   1. Bigcraft may be interplanetary if thus intended, but not FTL. They are NAFAL or STL.

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, Riders, 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 Super 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 immense World-Ships, very large Super Dreadnoughts, Superweapons, etc.

History & Background (Dossier)

Bigcraft with all their various missions remain popular throughout Charted Space for the simple reason that omitting a jump engine, hull grid, and related ship equipment is a tremendous savings in cost, manufacturing, and a number of other factors.

Jump Drives are tremendously expensive, complicated, and difficult to research and master. It's simply easier to design system ships for which there can be tremendously greater efficiencies of cost and manufacturing.
