NCIS Season 17, NCIS: Los Angeles Season 11, and NCIS: New Orleans Season 6 have all stopped production shy of completing the 24-episode order.
Unlike the shared universes of One Chicago, FBI/FBI: Most Wanted, and Grey’s Anatomy/Station 19, the three shows of the NCIS universe are set and film far apart from each other.
The seasons are expected to end prematurely rather than return to production.
No NCIS series has been renewed yet for 2020-2021.
