Serijo NCIS bodo gledalci lahko gledali vsaj do sezonskega leta 2017/18, saj je CBS serijo podaljšal za dve sezoni, t.j. do vključno 15. sezone. CBS je podaljšanje potrdil skupaj s potrditvijo dvoletnega sodelovanja z izvršnim producentom Markom Harmonom, ki poleg NCIS-a skrbi tudi za NCIS: New Orleans in delno tudi za NCIS: Los Angeles.
Glenn Geller predsednik CBS Entertainment je povedal: »It’s extraordinary that in its 13th season and with over 300 episodes to its credit, NCIS continues to excel at such a high level on a global scale. It is testimony to an amazing cast, led on and off the screen by the exceptional Mark Harmon, for skillfully bringing this universally appealing team of heroes to life; and to Gary Glasberg and his writers for crafting compelling stories that feature NCIS’ signature blend of mystery, quirk, drama and comedy every single week.«
Žal ni znano ali bo 15. Sezona NCIS-a v letu 2017/18 zadnja sezona, a do takrat je še daleč.
