Production After the season renewal, CBS revealed that the series would be returning to its original timeslot (held from seasons 1 to 18) on Tuesdays at 8pm, followed by NCIS: Origins and NCIS: Sydney at 9 and 10 p.m. respectively.
On September 4, it was announced a special crossover with the Origins spinoff celebrating U.S. Veterans on November 11, with a case that would span across decades. For this event, both series inverted their programming schedule. Also, Mark Harmon, Roma Maffia and Muse Watson reprised their roles as Leroy Jethro Gibbs, Vera Strickland and Mike Franks for the crossover.
This is the final season to feature Rocky Carroll as NCIS Director Leon Vance after 18 years, as Carroll was written out of the show in this season's 13th episode. However, he reappeared in the season finale for scenes set before his character's death. Carroll stated that while his character has been written off, he will continue to work behind the scenes as a director on the series.
