Mirror Universe hostiles in Star Trek Fleet Command are ships from the mirror timeline that spawn in Mirror systems (Mirror Sol, Mirror Kronos, Mirror Romulus and dozens more) from level 35 to 70, at warp 50 up to 800. Four groups fly there: the Terran Imperial Starfleet, the Alliance, the Romulan Republic, and a holographic Mirror Picard aboard the I.S.S. Enterprise-E. Most drop Raw Trellium, the Omega (Ω) versions drop Raw Omega-Trellium, and two mining ships pay Broken parts plus reputation. Almost all of them hull-breach your ship at the start of combat, which is the key to picking a crew.
Every Mirror Universe hostile at a glance
The table lists every Mirror Universe hostile with a fixed spawn, sorted by level. Most come in two flavors: a base version that drops Raw Trellium-A (and some Raw Trellium-D), and an Omega version marked Ω in game that drops the higher-grade Raw Omega-Trellium.

There are no armada or station targets in Mirror Universe space, so every entry is a straight ship kill. The Imperial Starfleet Cruiser, Exterminator and Warship also appear at more levels between 38 and 65 through events and the Arena, outside the fixed systems listed here.
Mirror Universe hostile locations by level
This table maps each level to its systems and the warp you need. The ships in each group spawn together, so one system gives you a choice of hulls. Omega space starts at level 40, when the Imperial Starfleet Ω ships appear in Mirror Orion and Mirror Rigel at warp 75, and the Alliance Ω ships join at level 48.

Crew for Mirror Universe hostiles
Almost every Mirror Universe ship carries Deadlock: at the start of combat it hull-breaches your ship for the whole fight. The same ships carry Dismantlement, which raises their weapon damage by 20% in any round your ship is hull breached, and Photophobia, which adds 10% Isolytic Damage under the same condition. Because the breach lasts all fight, those bonuses are always on. That shapes the crew question more than anything else.
- Build for survival first: officers that add mitigation, hull health or damage reduction keep you alive while their damage is boosted.
- Pick a captain that raises your damage against hostiles, so the fight ends before the boosted hits add up.
- Match the hull. The Alliance Galor-class and Alliance Ω-Galor-class come in all three combat hulls, so you can attack the version your ship counters.
For current officer picks at your level, the officer tier list keeps recommendations up to date, and crews shift with the meta. The Mirror research guide covers research that helps in Mirror space.
The I.S.S. Enterprise-E
The I.S.S. Enterprise-E is the special case. It is a level 50 to 70 Survey hull commanded by a holographic Mirror Picard, and its abilities work differently from the rest. Reflections applies Assimilate to your ship for two rounds at the start of each round. Take the Shot raises Mirror Picard’s Isolytic Cascade damage by 100% for two rounds, and Anticollective adds 30,000 Apex Barrier for a round whenever your ship is assimilated. Bring an endgame fleet with strong Isolytic defense for this one.
What Mirror Universe hostiles drop
Mirror Universe ships are tied to the Mirror Universe arc, and their signature reward is Trellium. The base Alliance and Romulan Republic ships and the I.S.S. Enterprise-E drop Raw Trellium-A and some Raw Trellium-D, the base Imperial Starfleet ships drop Raw Trellium-A, and the Omega versions drop Raw Omega-Trellium. You refine the raw material into Trellium to spend on the arc’s rewards.
Killing these ships does not pull a faction’s reputation down the way Klingon or Federation hostiles do. The two mining ships, the Imperial Starfleet Planet Harvester and the Romulan Republic Miner, pay Federation, Romulan and Klingon reputation all at once, on top of Broken parts for every combat hull (4★ up to 6★ by level). That makes them a rare target that builds three standings together.
Which ship should you bring?
Combat runs on a rock-paper-scissors between hull types: Interceptors beat Battleships, Battleships beat Explorers, and Explorers beat Interceptors. The Hull column tells you what each target flies, so bring the class that counters it. The Survey-hull targets have no combat counter, so you hit them with a strong warship crewed for hostile damage.
Worth-farming picks
- Early on, start with the level 35 ships in Mirror Bajor, Mirror Sol, Mirror Sirius, Mirror Wolf (Imperial Starfleet) and Mirror Cardassia (Alliance), all at warp 50.
- For the most Trellium per kill, move to the Omega ships. The Alliance Ω-Warbird, Ω-Bird-of-Prey and Ω-Recon cover Battleship, Interceptor and Explorer hulls from level 48 to 70, so you can pick the one your fleet counters.
- To build parts and reputation together, farm the Romulan Republic Miner or the Imperial Starfleet Planet Harvester.
- For an endgame challenge, the I.S.S. Enterprise-E drops both Raw Trellium-A and Raw Trellium-D, but its Mirror Picard abilities demand a strong fleet.
For the other factions, the hostile guide links every hub.
