The Imperial Starfleet Ω-Annihilator is a Mirror Universe hostile in Star Trek Fleet Command. It spawns as an Interceptor at fixed levels between 40 and 65, only in Mirror systems such as Mirror Orion, Mirror Deneva, and Mirror Tholus, and every kill drops Raw Omega-Trellium. Bring an Explorer to counter its Interceptor hull, and plan for a fast kill: it hull-breaches your ship the moment combat starts.
How to beat the Imperial Starfleet Ω-Annihilator
The Ω-Annihilator only appears as an Interceptor, so bring an Explorer. There is nothing to swap between levels; the same counter class works from level 40 all the way to 65. What changes is raw power. The jump from level 45 to level 51 multiplies its total strength by more than a hundred, so check the stat table below before you warp out to a higher tier.
What makes this hostile nastier than its numbers is its ability stack. Deadlock hull-breaches your ship at the start of combat and keeps the breach on for the entire fight. That breach then feeds its other ability, Dismantlement, which raises its weapon damage by 20% for a round whenever the enemy is hull breached at the start of the round, along with a companion effect, Photophobia, that raises its Isolytic Damage by 10% under the same condition. Since Deadlock keeps you breached from round one, both boosts are effectively always on. The takeaway: this fight does not reward stalling. Bring enough firepower to end it quickly, and expect hull repairs afterward.
For crew, follow the usual hostile-grinding principle: a captain that boosts weapon damage against hostiles, plus officers that add more damage or keep your ship standing longer. At these levels you are past the cadet-crew stage, so pick from your strongest hostile-hunting roster. Check the officer tier list for current picks; crews shift as the meta changes.
Where to find the Imperial Starfleet Ω-Annihilator
The Ω-Annihilator lives only in Mirror Universe space. The level 40 and 45 versions sit in warp 75 systems, the 51 and 55 versions need warp 200, and the level 65 version waits in Mirror Tholus at warp 700. Some of its spawn systems carry an Extract tag in the game data; those are marked in the table.
| Level | Warp | Systems |
|---|---|---|
| 40 | 75 | Mirror Orion, Mirror Rigel (Extract) |
| 45 | 75 | Mirror Deneva, Mirror Tellun (Extract) |
| 51 | 200 | Mirror Cita Laga |
| 55 | 200 | Mirror Kar, Mirror Suliban (Extract) |
| 65 | 700 | Mirror Tholus |
Rewards and what it drops
Every kill pays out Raw Omega-Trellium, from around 12 per kill at level 40 up to 9,000 at level 65. Ship XP scales the same way: 1,502 per kill at level 40, 3,300 at level 51, and 25,700 at level 65, which makes the top-level version a strong leveling target if your ship can survive it.
| Drop | What it is |
|---|---|
| Raw Omega-Trellium | The Mirror Universe resource. It refines into Omega-Trellium, the material you spend on Mirror Universe progression. |

Imperial Starfleet Ω-Annihilator firing pattern
The Ω-Annihilator carries four weapons, two Energy and two Kinetic, and all of them fire every round starting from round one. The Energy pair does most of the damage, hitting several times harder per shot than the Kinetic pair. There are no off-rounds to breathe in, and its breach-fed damage boost is active from the start, so incoming damage is steady and front-loaded. Survivability matters from the first round, not the last. The figures below come from the level 40 version; higher-level versions hit much harder.
| Weapon type | Count | Damage per shot | Fires | Crit |
|---|---|---|---|---|
| Energy | 2 | 90,158–244,995 | Every round | 10% (1.5x) |
| Kinetic | 2 | 45,079–48,999 | Every round | 10% (1.5x) |
The Imperial Starfleet in Star Trek
The Imperial Starfleet is the military arm of the Terran Empire, the brutal Mirror Universe counterpart to the Federation. It first appeared in the 1967 Original Series episode “Mirror, Mirror,” where a transporter accident swaps Kirk’s landing party with their ruthless doubles aboard the ISS Enterprise, a ship where officers advance by assassinating their superiors and discipline runs through the agony booth. The Enterprise two-parter “In a Mirror, Darkly” showed the 22nd-century Empire, and Star Trek: Discovery returned there with Emperor Philippa Georgiou. STFC’s Mirror Universe hostiles, this one included, fly under that empire’s banner.
Is the Imperial Starfleet Ω-Annihilator worth grinding?
Yes, if you are working through the game’s Mirror Universe content. It is a direct source of Raw Omega-Trellium, and the payout scales hard with level: the level 65 version drops up to 9,000 per kill plus 25,700 ship XP. The practical tips: match your warp range to the tier you can actually beat (75 gets you started, 700 for Mirror Tholus), bring an Explorer, and end fights fast before its breach-fed damage boost wears you down.
