Mon Calamari Cruiser

In the Star Wars fictional universe Mon Calamari Star Cruisers are the main cruisers in the Rebel/New Republic fleet for a significant portion of the Galactic Civil War. They were originally built for civilian purposes, but were converted to military starships when the Empire conquered Mon Calamari. While they are exceedingly durable starships, they are also notoriously difficult to repair, in part because of their individualized design.
