Modern-Era UNIT

UNIT appeared almost immediately in the new series, but they were a sporadic presence, appearing most prominently in “The Sontaran Stratagem,” “Journey’s End,” and “Planet of the Dead,” as well as various links to Torchwood (TV and audio) and The Sarah Jane Adventures. However, “The Power of Three” in the Eleventh Doctor’s era introduced the new-and-improved UNIT, led by Kate Stewart, with science taking the lead over military functions. In 2013, Big Finish acquired the rights to all new-series concepts up to and including the 50th anniversary special, which for UNIT mostly meant the characters of Kate and Osgood. So in their burst of new content that didn’t include the new-series Doctors, they kicked off a new UNIT series, filling in the gaps when the Doctor wasn’t around. Which lasted until 2019 or so, until “Spyfall” revealed that UNIT was defunct, and Big Finish put the series on hold. It returned in 2021, and was shown to be active on TV again in “The Power of the Doctor.” The gap has not yet been fully explained.
