Size-Role Classification
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.

Ship Classification by Size | |||||
---|---|---|---|---|---|
# | Type | Tonnage | Examples | Remarks | |
1. | Smallcraft | 0 to 99 tons | Smallcraft are typically Subcraft, designed to be carried by carrier craft. | ||
2. | Spacecraft | 100 tons or larger | Spacecraft are in-system vessels, lacking interstellar drives.
| ||
3. | Adventure Class Ships (ACS) | 100 to 2,499 tons | Adventure Class ships are usually jump-capable.
| ||
4. | Battle Class Ships (BCS) | 2,500 to about 1,000,000 tons | Battle Class ships are warships. They are usually jump-capable.
| ||
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.

Ship Tonnage & Organizational Schema
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:7-9 Tonnage Standards
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.
|
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.
|
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.
|
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.
|
TL:10-12 Tonnage Standards
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.
|
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.
|
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.
|
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.
|
TL:13-15 Tonnage Standards
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.
|
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.
|
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.

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.
