The Size-Role Classification, often abbreviated as Size-Cat or Size-cat, is a measure of a ship's size in tonnage and its rough correspondence with its mission roles, logistics, and other vessel characteristics.

Naval Ship Synopsis by Size-Role[edit]

Ship Classification by Size in TL:13-15 [1]
# Type Tonnage Class Commonality Remarks
1. Smallcraft (Subcraft) 0 to 99 tons Vehicle Ubiquitous Smallcraft are NAFAL or STL.
2. Bigcraft (Subcraft) 100 tons or larger Vehicle or Ship Uncommon Bigcraft are designed for NAFAL capabilities, but some mistakenly call them FTL.
3. Largecraft (Non-subcraft) 100 tons or larger Vehicle or Ship Uncommon Largecraft are designed FTL.
4. Adventure Class Ships (ACS) 100 to 2,499 tons Ship or Vessel Common Adventure Class ships may be FTL or NAFAL.
5. Battle Class Ships (BCS) 2,500 to 249,999 tons Ship or Vessel Uncommon Battle Class ships may be FTL or NAFAL.
6. Fleet Class Ships (FCS) 250,000 to 999,999 tons Ship or Vessel Rare Fleet Class ships may be FTL or NAFAL.
7. World Class Ships (WCS) 1,000,000 tons or larger Ship or Vessel Ultra-rare World Class ships may be FTL or NAFAL.

Ship Tonnage & Organizational Schema[edit]

A number of Basic Ship Size-Role Classifications are based upon the relative size of a ship in tonnage terms:

But this is problematic, because by the end of every three tech levels (...or tech epoch), the maximum of minimum size of naval architecture, these parameters change. The Imperial Navy and the Imperial Interstellar Scout Service have employed a system based upon rough standards based on tech epochs over its many centuries of experience.

TL:13-15 Tonnage Standards[edit]

Tonnage Standards by Tech Epoch: TL:13-15
Size-Class Tech Epoch Tonnage Remarks
ACS TL:13-15 100 to 2,499 tons These vessels can be operated by small crews, supported by minor organizations, and serviced at almost any major shipyard or starport.
  • They vessels tend to conduct the lion's share of private and commercial activity for any given sophontic society at this tech epoch.
BCS TL:13-15 2,500 to 249,999 tons These vessels require significant shipyards to construct and represent large-scale investment of funds, personnel, and resources.
  • They conduct all of paramilitary and military missions of a major polity.
FCS TL:13-15 250,000 to 999,999 tons Around 500k tonnage is considered the largest practical size in terms of cost-time benefit.
  • Only a limited number of these vessels may be built so only major combatants, very serious industrial & scientific applications, or major government projects will build ships in this size range.
WCS TL:13-15 1,000,000 tons or larger Such vessels are beyond expensive and represent suprapolity-level investment in many, many RU's that take years to manufacture and sometimes decades.
  • These ships are almost impossibly large for their time and take several generations of leaders and a focused society to construct. They are only built for immensely important missions.

TL:10-12 Tonnage Standards[edit]

Tonnage Standards by Tech Epoch: TL:10-12
Size-Class Tech Epoch Tonnage Remarks
ACS TL:10-12 100 to 1,999 tons These vessels can be operated by small crews, supported by minor organizations, and serviced at almost any major shipyard or starport.
  • They vessels tend to conduct the lion's share of private and commercial activity for any given sophontic society at this tech epoch.
BCS TL:10-12 2,000 to 199,999 tons These vessels require significant shipyards to construct and represent large-scale investment of funds, personnel, and resources.
  • They conduct all of paramilitary and military missions of a major polity.
FCS TL:10-12 200,000 tons to 749,999 tons Around 250k tonnage is considered the largest practical size in terms of cost-time benefit.
  • Only a limited number of these vessels may be built so only major combatants, very serious industrial & scientific applications, or major government projects will build ships in this size range.
WCS TL:10-12 750,000 tons or larger Such vessels are beyond expensive and represent suprapolity-level investment in many, many RU's that take years to manufacture and sometimes decades.
  • These ships are almost impossibly large for their time and take several generations of leaders and a focused society to construct. They are only built for immensely important missions.

TL:7-9 Tonnage Standards[edit]

Tonnage Standards by Tech Epoch: TL:7-9
Size-Class Tech Epoch Tonnage Remarks
ACS TL:7-9 100 to 999 tons These vessels can be operated by small crews, supported by minor organizations, and serviced at almost any major shipyard or starport.
  • They vessels tend to conduct the lion's share of private and commercial activity for any given sophontic society at this tech epoch.
BCS TL:7-9 1,000 to 149,999 tons These vessels require significant shipyards to construct and represent large-scale investment of funds, personnel, and resources.
  • They conduct all of paramilitary and military missions of a major polity.
FCS TL:7-9 150,000 to 499,999 tons Around 100k tonnage is considered the largest practical size in terms of cost-time benefit.
  • Only a limited number of these vessels may be built so only major combatants, very serious industrial & scientific applications, or major government projects will build ships in this size range.
WCS TL:7-9 500,000 tons or larger Such vessels are beyond expensive and represent suprapolity-level investment in many, many RU's that take years to manufacture and sometimes decades.
  • These ships are almost impossibly large for their time and take several generations of leaders and a focused society to construct. They are only built for immensely important missions.
