Pelta-class Command Ship

The Pelta-class Command Ship was a variant of the Pelta-class frigate. The Alliance to Restore the Republic used modified Pelta-class Command Ships during the Galactic Civil War.

Behind the scenes
When Matt Martin was asked on Twitter if MC30c frigates were in the canon continuity due to containing both a modified Pelta-class Command Ship, a variant of the modified Pelta-class frigates used by the Rebel Alliance in canon, first seen in the Star Wars Rebels Season Two premier, Star Wars Rebels: The Siege of Lothal, and a MC30c, Matt Martin stated that although he did not know about the MC30c's existence in the canon continuity, it was his opinion was that he wouldn't rule out the possibility, especially given its McQuarrie roots.
