Based on the increased interest in the property, a digital-first ongoing series written by Marguerite Bennett and various artists began in July 2015, with a printed comic book following in 12 August. The series ran for 100 digital issues, concluding in June 2017 and 33 print issues with the final issue release in August.

In her initial conception for building a narrative out of Ant Lucia's designs, Marguerite Bennett has stated: "We were able to retro-engineer this complete environment that lets them showcase their powers that lets them have good relationships and friendships that they wouldn't have been able to explore in another sphere....Going down to the smallest details that [Ant Lucia] puts into the statues and creating whole backstories for items". Bennett also speaks on her decision to incorporate mainstream canonical backstories of characters in this new world.

Bennett explored traditional genres and mediums of the 1940s such as radio shows and propaganda films to provide a realistic history for the Bombshells franchise. Bennett speaks on this decision when she states: "Each of the heroines actually has, essentially, her own genre. Batwoman started off as this cheesy radio adventure reel, Wonder Woman is a war story, Supergirl is a propaganda film, Zatanna is this Hammer horror film, Catwoman is like a noir spy story". Bennett concludes and acknowledges the importance of the decision: "We were able to complete this whole new world that wasn't just one thing because no woman is just one thing. So they each got to have a distinct voice, a distinct personality". The foundation of feminist tones in the comic are seen in the structure of this atypical history as Bennett says: "We wanted to make a principle of the series to have the conceit that in this alternate history World War II the women came first. No heroine is derivative of a male counterpart. They are the heroes".
