## Production

NCIS was renewed for a seventeenth season on April 11, 2019.
On March 13, 2020, CBS announced that the filming of season 17 had been suspended due to the COVID-19 pandemic. Storylines planned for what would have been Episodes 21–24 are confirmed to have been integrated into the Season 18 episodes "Everything Starts Somewhere" and "Sunburn." Executive producer Frank Cardea teased a "very surprising ending" that was altered due to the pandemic. Fans have speculated that this was either the exit of Maria Bello's Jacqueline Sloane (which was postponed until the Season 18 episode "True Believer") or an on-screen reunion of former main cast members Michael Weatherly and Cote de Pablo as Tony DiNozzo and Ziva David, though neither theory was confirmed.
This is the first and only season not to feature Joe Spano in his recurring role as Tobias Fornell, though he is mentioned numerous times in the season's eighth episode, "Musical Chairs." The fact that the opening arc of the next season would conclude the episode's arc regarding Fornell and his daughter, which began in the Season 16 finale, has led to speculation that this story was intended to be the basis for the unproduced final episode of Season 17.

## Broadcast

The seventeenth season of NCIS premiered on September 24, 2019.
