The Automated Personnel Unit is an Epic Chaos Tech in Star Trek Fleet Command, built to turn one ship into a much faster hostile killer. Its headline buff raises Weapon Damage against non-Armada hostiles from 20% at unlock to 3,500% at max, and it stacks Isolytic Damage and Apex Barrier on top. The catch is that every buff only works on the U.S.S. Vengeance and FKR ships, so this is a specialist piece for a specific grinder rather than a slot for everyone.
What Automated Personnel Unit does
The Automated Personnel Unit carries three buffs, and all of them point at non-Armada hostiles while the ship in question is the U.S.S. Vengeance or an FKR ship. The Weapon Damage buff is active from tier 1 and does the heavy lifting, pushing your damage output far past what the ship manages on its own. Isolytic Damage rides alongside it from tier 1, and Apex Barrier switches on at tier 2 for a layer of survivability.
| Buff | Unlocks at tier | Unlock value | Max value |
|---|---|---|---|
| Increases Weapon Damage against non-Armada hostiles | 1 | 20% | 3,500% |
| Increases Isolytic Damage against non-Armada hostiles | 1 | 1% | 150% |
| Increases Apex Barrier against non-Armada hostiles | 2 | 40 | 5,000 |
Values are current as of the latest game data and scale with the item’s level between those two endpoints. The Weapon Damage number is the reason to run this piece, since it lets a fitted Vengeance or FKR ship one-shot targets it would otherwise grind through slowly. One caveat worth knowing: the Apex Barrier buff does not apply when Tal is assigned to the bridge, so plan your crew around it.
How to get Automated Personnel Unit
The Automated Personnel Unit runs on the Chaos Tech system rather than the standard Forbidden Tech track. You slot Chaos Tech onto a ship using Chaos Tech Fusion Rods, which also let you remove a piece from a ship later; you earn Fusion Rods in the Continuum refinery or the store. The materials that build and upgrade the piece flow through the same refinery. Chaos Tech Fragments exchange into Chaos Tech materials there, and you pick up extra Fragments whenever you gather surplus Chaos Tech shards. The heavier upgrade currencies come from combat, covered below.
Upgrading Automated Personnel Unit
Chaos Tech has two upgrade paths. Tiering up with Chaos Tech Tier-Up Catalysts raises the level cap and unlocks the Apex Barrier buff at tier 2. Leveling up with Chaosmatter and Chaos Tech Reactors scales the buff values toward their maximums. Both of those level-up resources come from defeating Assimilated El-Aurian hostiles and exchanging their loot in the Continuum refinery, or from the store.
| Tier | Level cap | Cost |
|---|---|---|
| 1 | 5 | Starting tier |
| 7 | 35 | 18,000 Chaos Tech Tier-Up Catalyst |
| 12 | 60 | 22,000 Chaos Tech Tier-Up Catalyst |
Reaching tier 12 costs 182,800 Chaos Tech Tier-Up Catalyst in total. Taking the piece from level 2 to its level 60 cap costs another 112,800 Chaos Tech Reactor and 261,475 Chaosmatter. The tier 2 unlock is the early milestone worth pushing for, since it adds the Apex Barrier buff rather than a bigger number on an existing one; after that, levels are what grow the Weapon Damage buff toward its ceiling.
Best ships and uses for Automated Personnel Unit
This piece belongs on the U.S.S. Vengeance or an FKR ship that you use to grind hostiles, and nowhere else. Every buff reads “against non-Armada hostiles,” so it does nothing in PvP, against armadas, or while mining, and it is inert on any ship outside those two hulls. On the right ship the Weapon Damage buff lets you punch well above your normal weight against tough single targets, while Apex Barrier keeps you alive through longer fights. Remember to keep Tal off the bridge if you want that barrier to count. Pair it with your usual hostile crew and work through the hardest targets you can clear quickly; our hostile guide covers where to hunt at each level.
Automated Personnel Unit in Star Trek
The Automated Personnel Unit is a game concept rather than a device from the shows or films, so there is no screen canon to draw on. Its in-game story fits the wider Star Trek Fleet Command setting: the Federation first built APU systems for autonomous patrol vessels meant to defend remote sectors where a full crew was impractical, coordinating weapons and targeting through adaptive tactical algorithms. Starfleet rejected fully autonomous warships, but the technology spread to the very factions it was meant to hold off, and later versions were rebuilt to support experienced crews instead of replacing them. The ship it buffs, the U.S.S. Vengeance, is itself a nod to the Section 31 dreadnought from Star Trek Into Darkness.
Is Automated Personnel Unit worth it?
It depends entirely on your ships. If the U.S.S. Vengeance or an FKR ship is your daily hostile grinder, the Weapon Damage buff is one of the biggest single boosts you can slot, and the piece earns its keep fast. If those ships are not part of your rotation, the Automated Personnel Unit does nothing for you, and your Chaos Tech materials are better spent elsewhere. For owners who do run it, push to tier 2 for Apex Barrier, then level it as materials allow.
