Fans of The Last Ship noted with interest that cast member Travis Van Winkle recently posted (and subsequently deleted) on Instagram after wrapping production on Season 5, referring to a “series wrap.”

TNT responded with a statement, “We shot two seasons simultaneously, the fourth is currently on the air and the fifth will return next summer. We greenlit the fifth with the idea that it could be the final season, however it’s far too early to make that determination.”

But Deadline is speculating any return is unlikely.

“I hear those involved in the series do not expect it to go beyond five seasons,” it notes.

The Last Ship star Eric Dane was recently approached to star in a new TV series and, while he ended up passing on the project, I hear he had been made available and is free and clear to take other jobs. Additionally, I hear Season 5 is not ending in a cliffhanger, which could’ve been used to write off Dane’s character and would’ve made it harder to end the series.”

It screens in Australia on Stan.
