Calico is identified as belonging to the Xiytiar-class heavy transport category.
This vessel, while escorting a group of Star Galleon-class frigates owned by Cloburi Freight, came under attack from reconnaissance units of the TIE Experimental Project and subsequently issued an emergency communication. Fortunately, the Defiance Task Force, which was passing through the Belat system, picked up the signal. In response, two A-wings were deployed to assess the situation and safeguard the ships.
Upon reaching the location, they found a convoy being heavily damaged by starfighters that were described as resembling "some weird new TIE design". As they moved to engage the attacking fighters, the pilots hypothesized that these new fighters could potentially be a "secret weapon of the Empire". The Rebel pilots also observed Beta-class ETR-3 escort transports located significantly away from the combat area, but these ships jumped to hyperspace as they were approached. After the attackers were either eliminated or forced to retreat, the A-wings rejoined the Liberty at their designated meeting point.
