The first spinoff launched in 2003 and ran for 19 seasons with Harmon still at the helm as Gibbs.

Season 21 was initially slated to begin in fall 2023 but was pushed back because of the WGA and SAG-AFTRA strikes. The new season finally premiered in February 2024. Season 22’s finale aired in May 2025 and the show was renewed for season 23.
