Who is Caleb Mir in STFC?
Caleb Mir is a Rare Engineering officer in Star Trek Fleet Command, attached to the Starfleet Academy crew group. He arrived alongside the rest of the Academy roster from the 2026 Paramount+ series Star Trek: Starfleet Academy.
His draw is a single shield buff that fires at the start of a round when you are attacking Outposts or non-Armada hostiles. He has no captain’s maneuver, so he earns his seat as a bridge officer, not as the captain.
If you grind hostiles or hit other players’ stations, he is worth a place on the bench. If you want a captain to anchor a crew, look elsewhere.
Star Trek background
Caleb Mir comes from Star Trek: Starfleet Academy, the Paramount+ series that premiered in January 2026 and is set in the 32nd century. Sandro Rosta plays the part. The era is the post-Burn Federation, the period after a dilithium collapse cut Federation worlds off from each other.
Caleb grew up on a Federation industrial colony, starving with his mother Anisha. She was caught working with the pirate Nus Braka in a robbery that killed a Starfleet officer, and she was sent to a penal colony. Captain Nahla Ake delivered the sentence and promised to look after the boy, but Caleb fled into a sandstorm before she could.
He spent his teens and early twenties on the run. By age 21 he had a long rap sheet across Federation, Ferengi, Orion, Trill, Andoria, and Cardassian space. Captain Ake, now chancellor of the rebuilt Starfleet Academy, gets him released into her custody aboard the USS Athena and tells him his mother escaped from prison a year earlier. He enrolls as a cadet, reluctantly, with the goal of finding her.
In the pilot, “Kids These Days,” Caleb shows a real gift for engineering. He uses programmable matter to fix the Athena’s life support during a training drill, and later he activates the main deflector to reprogram an attack made of programmable matter that has wrapped itself around the hull. That moment is where his STFC officer ability gets its name.
Role in STFC
Caleb Mir is a specialist. He is a Rare Engineering officer in the Starfleet Academy synergy group, and the reason to use him is one thing: extra Shield Health when you engage Outposts or non-Armada hostiles. The bonus fires on round start and scales as you promote him.
That gives him a clear lane. He fits crews aimed at killing PvE hostiles or sieging another player’s Outpost. He is not a damage officer, and he is not built for mining defense, Armadas, or open-space PvP between fleets. On every crew he runs in an officer slot.
Captain ability and officer ability
Captain ability: Chain of Command
Caleb Mir’s captain ability is blank. The in-game text reads “This Officer does not have a Captain’s Maneuver. Equipping this Officer as the captain of a ship provides no benefit.” Treat the captain slot as off-limits for him and put a real captain there.
Officer ability: Programmable Matter Prodigy
When Caleb is on the bridge, your ship gets a Shield Health bonus on round start whenever the target is an Outpost or a non-Armada hostile. The bonus grows with each rank. The values below are as of the latest game data.
| Rang | Shield Health bonus |
|---|---|
| 1 | 7% |
| 2 | 9% |
| 3 | 14% |
| 4 | 20% |
| 5 | 30% |
Ranks 1 and 2 are soft. The jump from rank 3 to rank 4 is where the bonus starts to feel real, and rank 5 is where you would actually notice his seat on the bridge.
Where Caleb Mir shines
The use cases are narrow but real.
- Hostile grinding against non-Armada targets. If you farm Klingon, Romulan, Federation, or Independent hostiles for parts, loot, or daily missions, the shield bonus helps you tank more rounds before swapping ships.
- Outpost attacks during war or to break a base. The bonus applies to Outposts the same way it applies to hostiles, so he is a low-cost shield helper for players cracking another commander’s station.
- Builds that lean on shield HP. Battleships that survive by absorbing rounds get more out of him than a glass-cannon Interceptor would.
Where he is not the answer: Armada fights, PvP between fleets in open space, mining defense, or any crew built around using his captain seat.
How to get Caleb Mir
Caleb Mir ships with the Starfleet Academy roster, so look for him in event rotations and store offers tied to that group. Specific drop sources move with the patch cycle, so check the current store and event rotations in-game rather than relying on a static list. Reaching rank 5 takes 588 shards in total: 38 to clear rank 1, 55 more to rank 2, 115 to rank 3, 155 to rank 4, and 225 to finish the climb to rank 5.
Synergies and crew building
Caleb Mir sits in the Starfleet Academy synergy group, so he picks up bridge bonuses when paired with other officers from the same group. His ability fires on its own as long as the target is an Outpost or a non-Armada hostile, so he does not need a specific partner to function.
Class synergy percentages for this officer are not in the public game data, so build by purpose rather than chasing a synergy chart. Pair him with a captain whose maneuver fits the fight you are taking, and round out the bridge with another officer that boosts shields or buys time. If you have other Starfleet Academy officers on the bench, stacking them with Caleb on the same bridge gives you a little extra group synergy on top of his shield bonus.
Character traits
Caleb Mir has the standard two-trait setup that Rare officers carry. You upgrade traits by spending an officer-XP resource at increasing levels. The first trait caps at three levels with a gentler cost curve, and the second trait caps at four levels and costs more per upgrade.
Trait costs add up quickly, so save your trait XP for officers you actually use on the bridge often. With Caleb’s narrow role, only level his traits if you keep him in a hostile- or Outpost-killing crew long-term. If you barely use him, leave the traits alone.
Frequently asked questions
Is Caleb Mir any good in STFC?
He is good in his lane and limited outside it. If you grind hostiles or crack Outposts, rank 4 and rank 5 give a real shield cushion. If you want an all-purpose bridge officer or a captain, look elsewhere.
Where do you get Caleb Mir shards?
He drops with the Starfleet Academy officer group through events, recruit chests, and faction or event stores tied to that crew. The exact source rotates, so check current store and event availability in-game.
What ship is Caleb Mir best on?
Any ship you take into hostile farming or Outpost fights. Battleships and other survivability-focused hulls get the most out of his shield bonus. He does not need a specific ship class to work.
Does Caleb Mir have a captain ability?
No. His captain slot is blank. The in-game text reads “This Officer does not have a Captain’s Maneuver.” Always seat him as a regular bridge officer.
Is Caleb Mir worth ranking up?
At rank 1 to 3 he is mild. Rank 4 (20%) and rank 5 (30%) are where the shield buff matters. If a more general officer is competing for the same shards, prioritize that officer first. If you already use a hostile- or Outpost-killing crew that wants more shield HP, push him to rank 5.
Bottom line
Caleb Mir is a single-purpose officer. He brings one strong effect to a specific kind of fight, no captain ability, and a clear rank curve that pays off late. If you have a hostile-grinding crew or a PvP Outpost-cracking setup that wants more shield HP and is short an officer slot, rank him up. If you are spreading shards across many officers, he can wait until you have a use for him.
