The project has Kou Matsuo directing it and working on the scripts with it naturally being animated at Sunrise.
Sunrise confirmed at Anime Expo this weekend that the second season of Mobile Suit Gundam Thunderbolt will indeed be getting a dub with it getting a debut in August in Japan as part of the Sunrise Festival.
The Thunderbolt Sector is a shoal zone composed of the debris of destroyed space colonies, named for the electrical discharges from the metal debris.
While it was almost a given there’s definitely something to be said for getting it confirmed.
