Production
In November 2011, announced that he would put his other manga series, Moonlight Mile, on hiatus to start a new project, which was later revealed to be a Gundam mini-series. Mobile Suit Gundam Thunderbolt started in Shogakukan's manga magazine Big Comic Superior magazine on 23 March 2012.Ohtagaki described the manga as a realistic war story for adults, employing a harsh tone, mechanical realism, and a jazz motif that dictates its rhythm and atmosphere. His goal was to create a work "adult fans can empathize with," using cinematic techniques for pacing and sound on the page. The series was later stated to occupy its own separate "worldline", distinct from the main Universal Century canon.
In September 2018, it was announced that Ohtagaki would place the manga on hiatus due to tenosynovitis. Upon its return in December, he announced a permanent change to his drawing style to accommodate the condition in his dominant left hand, acknowledging that this might affect the series' visual quality and receive a mixed response from fans; the manga has had other hiatuses since then. In June 2025, it was announced that the manga would end in eight chapters. The series finished on 26 September 2025.
