Here's another look at the aircraft I designed for "Star Trek Beyond", dubbed the "Battle Shuttle". It was created for an earlier version of the script, and unfortunately was cut from the final script, but perhaps influenced the enemy "Swarm Ships" we do see in the final film. Both are small, dart-like fighters, ultra-maneuverable, and can carry a pilot and 2-3 passengers in a toboggan tandem style seating.
UPDATE: Martinez has posted a couple more images of the fighter:
Martinez also did lots of work designing the planet Altamid. He posted lots of different variants on his Facebook page, I've picked out my favourite of the surface and underground here, but you'll find more on Facebook:
He did even more work on Altamid, interestingly quite late in the production:
Here are some concepts I did for the Altamid Mines in "Star Trek Beyond" showing the docking bay for the enemy swarm ships, the mine shafts, and prisoner restraints. These were actually part of additional scenes that were added after the film was shot and edited, and the director felt it needed these additional designs to better round out the movie. It was great working with Production Designer Andrew Murdock on these as well as Set Designer Jeff Markwith!
You can see more of Martinez' work from the film on his Facebook profile. To keep track of all the latest information on Star Trek Beyond, including more concept art and other behind the scenes coverage, visit my Star Trek Beyond guide page.
