What is the Star Trek Lower Decks season 4 release date? The new era of Star Trek has been full of surprises, and it’s perhaps Lower Decks that’s been the biggest surprise of all.
The animated series takes place in the late 24th century, sandwiched between the end of the Dominion War and the start of Star Trek Picard. Rather than focussing on the bridge crew (like the show’s senior officers and Star Trek captain) Lower Decks explores the adventures of the lowly ensigns and lieutenant junior grades. Despite this, the Star Trek series still has that distinct Star Trek feel. Here’s what we know about the upcoming Star Trek Lower Decks season 4 release date and more.
Star Trek Lower Decks season 4 release date speculation
Star Trek Lower Decks season 4 release date is scheduled for summer 2023, but no specific date has been confirmed.
However, the comedy series will likely drop towards the end of the summer to make a gap between its start and the end of Star Trek Strange New Worlds season 2, which will begin in late spring.
The news was confirmed in March 2023, when Lower Decks was also renewed for season 5.
Star Trek Lower Decks season 4 cast
Star Trek Lower Decks season 4 cast will include returning cast members from previous seasons aboard the USS Cerritos, as well as guest stars.
This means the likes of Tawny Newsome and Jack Quaid will be front and centre, as will all their friends, frenemies, and new acquaintances too.
The Star Trek Lower Decks season 4 cast list:
- Tawny Newsome as Beckett Mariner
- Jack Quaid as Brad Boimler
- Noël Wells as D’Vana Tendi
- Eugene Cordero as Sam Rutherford
- Gabrielle Ruiz as T’Lyn
- Dawnn Lewis as Carol Freeman
- Jerry O’Connell as Jack Ransom
- Fred Tatasciore as Shax
- Gillian Vigman as T’Ana
In season 3, there were also plenty of guest stars, such as Nana Visitor, Armin Shimerman, and James Cromwell, reprising their roles as Kira Nerys, Quark, and Zefram Cochrane, respectively. Expect much more of that.
Star Trek Lower Decks season 4 plot
Star Trek Lower Decks season 4 plot has been confirmed by Mike McMahan (the creator of the show) in a post to Twitter, and it sounds like a blend of classic adventures and a bigger, more intimidating threat.
McMahan shared: “In season 4 of Star Trek Lower Decks, an unknown force is destroying starships and threatening galactic peace.
“Luckily,” continued McMahan, “the crew of the USS Ceritos isn’t important enough for stuff like that! Instead, Ensigns Mariner, Boimler, Tendi, Rutherford, and provisional Ensign T’Lyn are keeping up with their Starfleet duties, avoiding malevolent computers and getting stuck in a couple of caves- all while encountering new and classic aliens along the way…”
That sounds a lot like seasons which have come before, with the added benefit of an exciting new member of the crew. Of course, fans will also want to know more about that destructive “unknown force.” Interesting.
