Hangar D-13 was a specific hangar located on the Thunderer, a Resurgent-class Star Destroyer belonging to the First Order. During 34 ABY, Tamara Ryvora, a TIE pilot, found herself being interrogated by Agent Tierny about her activities as she prepared her TIE fighter for what was actually her desertion from the First Order, departing from the Star Destroyer. Ryvora responded by stating that she was getting her TIE ready for a training exercise that she would be leading. The agent then voiced her understanding that the training was scheduled to occur within Hangar D-13, to which the pilot replied that Operations must have relocated it to a different hangar. Tierny then gave the pilot DT-798 instructions to provide assistance to Ryvora. Soon after this exchange, both the Star Destroyer and Hangar D-13 met their end, being destroyed in the Barabesh system by the residents of Colossus, the supertanker fuel depot.
The two-part episode "The Escape," which serves as the finale for the second season of Star Wars Resistance, an animated television show, featured a mention of Hangar D-13 in its first part. This episode was broadcast on January 26, 2020.
