Iron Squadron's spaceship is a YT-2400 named 'Sato's Hammer'. This vehicle was originally developed by Doug Chiang as a background vehicle briefly seen in the 1997 Special Edition of Star Wars: Épisode IV - Un nouvel espoir (1977), and became Dash Rendar's ship, the 'Outrider' in the 1996 multi-media project Shadows of the Empire.
The planet Mykapo was named after Mickey Capoferri, Executive Producer of Rebels Recon and The Star Wars Show (2016).
When Mart Mattin is first shown, the Aurebesh text on the device he is working on translates to "device armed". Later, when he is shown in the cockpit of his YT-2400, the 'warning' appears on one of the screens in Aurebesh.
Mart Mattin was named and designed after Matt Martin, Lucasfilm's manager of digital content and community relations.
Gooti Terez was named and designed after Andi Gutierrez, a digital communications manager at Lucasfilm, host of Rebels Recon, and co-host on The Star Wars Show.
