The SGS-45 Quarrel, a gunship design, was manufactured by Republic Sienar Systems for use by the Republic Navy. It participated in the Galactic War against the Sith Empire. This vessel was equipped with rail guns that could be configured to fire ion, plasma, or standard projectiles, enabling it to engage enemies from a significant distance. While possessing strong armament, its speed was considered lacking.
In Star Wars: The Old Republic: Galactic Starfighter, a Digital Expansion released in 2013 for the video game Star Wars: The Old Republic, the SGS-45 Quarrel is one of five gunship options for Republic players. Unlocking it requires 2,500 Fleet Requisition points. It serves as the Republic's long-range gunship, mirrored by the GSS-3 Mangler in the Imperial faction.
