This papercraft is the Taiidan Repair Corvette, from the critically-acclaimed first installment in the computer game series Homeworld, the paper model was created by EmteeMoe. Taiidan Repair Corvette have been for a long time the mainstay of a fleet and their main purpose has been to refuel and repair fighters. They can however repair larger ships such as other corvettes or capital ships. The Taiidan repair corvette is no exception to this rule and carries a repair beam similar to the phased disassembler array to help it in its duties.
Repair corvettes are at a defensive disadvantage as they have very weak armor and a single gun turret to protect them from swarms of strike craft. [Source: wikia]
