The news was announced at San Diego Comic-Con on Friday (July 26) during a panel moderated by Josh Horowitz with stars Ncuti Gatwa and Millie Gibson and showrunner Russell T Davies.
Russel Tovey and Gugu Mbatha-Raw will lead the new spin-off series titled, The War Between the Land and the Sea.
"When a fearsome and ancient species emerges from the ocean, dramatically revealing themselves to humanity, an international crisis is triggered," an official description reads. "With the entire population at risk, UNIT steps into action as the land and sea wage war."
Created by Davies, the series features the return of the Sea Devils, classic Doctor Who villains first seen in 1972.
Davies said in a statement: "I'm so lucky to work with such a magnificent cast. And this is a huge, muscular, thrilling drama which will shake The Whoniverse to its foundations. When the Doctor's not in town, the whole of humanity is in trouble."
Filming begins next month and will be directed by Dylan Holmes-Williams, director of two Doctor Who season one episodes: "73 Yards" and "Dot and Bubble." The series will air exclusively on Disney+ in the US and BBC One and BBC iPlayer in the UK.
The War Between The Land And The Sea is produced by Bad Wolf, with BBC Studios for Disney Branded Television and BBC. In addition to Davies, executive producers include Phil Collinson, Joel Collins, Julie Gardner and Jane Tranter.
Gatwa and Gibson return to Doctor Who next season and will welcome Varada Sethu (Andor) as a new companion to the Doctor. Gibson also announced that The Little Mermaid star Jonah Hauer-King will join the cast of the new season as part of Ruby's story.
Elsewhere in the panel, Nicola Coughlan introduced the first trailer for the forthcoming Doctor Who Christmas special.
She stars as "a determined woman whose life is changed forever when she meets the Doctor."
"She's an absolute star," Gatwa said of the Irish actor.
