The Doomsday Worm is a Neutral hostile in Star Trek Fleet Command that roams levels 27 to 46. It spawns as three hull types (Battleship, Explorer, and Interceptor), so the ship you bring depends on which variant you target. You will find it across warp 20 to 27 systems in neutral space, and it drops Parsteel, Dilithium, and Tritanium. To beat it, bring the hull class that counters the variant you are hunting and match its warp.
How to beat the Doomsday Worm
The Doomsday Worm appears as all three combat hull types, so no single ship counters every version. Combat in STFC runs on a rock-paper-scissors triangle: Interceptors beat Battleships, Battleships beat Explorers, and Explorers beat Interceptors. Survey ships barely fight, so leave them docked. Check which hull the Worm is showing in your target system, then bring its counter: an Interceptor against the Battleship variant, a Battleship against the Explorer variant, and an Explorer against the Interceptor variant.
Tap the target before you engage to read its hull class, since the same system can hold different variants at different levels. The Worm has no combat ability that shifts mid-fight, so once you bring the right hull the battle stays predictable: mitigate the incoming damage, out-damage its hull, and repair between runs. If you send the wrong class, the hull penalty can flip an easy kill into a loss even when your ship power looks higher on paper.
For crew, put a captain that boosts weapon damage against hostiles in the captain’s chair, then fill the other seats with officers that add damage or mitigation. At these levels a cadet crew still holds up: Cadet Kirk as captain with Cadet Spock and Cadet Uhura is a cheap, reliable setup that carries most players through the twenties and thirties. For current top picks, check the officer tier list. Crews shift with the meta, so treat any named lineup as a starting point rather than a fixed answer.
Where to find the Doomsday Worm
The Doomsday Worm clusters in neutral systems that scale with its level. The low-level spawns sit around warp 20 to 24 in systems like Elya, Piya, and Villo, while the higher levels push out to warp 27 in deeper systems such as Hollin, Kendi, and Zin-45. Warp range is the real gate here: if your ships cannot reach warp 27, you are capped at the level 36 and lower spawns until you research more warp. Pick a system that matches both the level you can beat and the warp you can reach, then park nearby so you are not burning travel time between kills.

Rewards and what it drops
Every Doomsday Worm kill pays out three core resources. These are the materials you burn through building and upgrading, so the Worm is a steady farm if you are short on any of them at this stage. Parsteel and Tritanium feed your base upgrades and ship builds through the mid-game, and the Dilithium adds up over a long grind session for speedups or refining. Ship XP also scales with level, climbing from about 590 at level 27 to roughly 1,196 at level 46, so the higher spawns level whatever ship you are flying faster than the low ones.
| Drop | What it is |
|---|---|
| Parsteel | Base building material used for most structures and upgrades |
| Dilithium | Premium currency for speedups, refining, and research |
| Tritanium | Mid-tier building material for higher-level structures and ship components |
Doomsday Worm stats
Stats vary by hull variant and climb steeply with level. The rows below use the Explorer variant as the anchor at the low, mid, and high ends of its range.
| Level | Total strength | Hull HP | Shield HP | Attack | Defense | Ship XP |
|---|---|---|---|---|---|---|
| 27 | 133,465 | 29,700 | 31,350 | 50,440 | 52,500 | 590 |
| 39 | 4,339,888 | 1,974,818 | 2,513,406 | 1,412,386 | 683,390 | 868 |
| 46 | 12,250,268 | 5,308,581 | 6,756,380 | 4,394,213 | 1,823,575 | 1,196 |
Doomsday Worm firing pattern
The Doomsday Worm carries two weapon groups. Its pair of energy weapons fire every round for steady pressure, while its single kinetic weapon hits much harder but only fires every other round. Time your repairs or mitigation around the kinetic volley, since that is the shot that lands the biggest hits. The figures below come from the lowest-level spawn and scale up with level.
| Weapon type | Count | Damage per shot | Fires | Crit |
|---|---|---|---|---|
| Energy | 2 | 7,200–8,800 | Every round | 10% (1.5x) |
| Kinetic | 1 | 17,280–21,120 | Every other round | 10% (1.5x) |
Is the Doomsday Worm worth grinding?
The Doomsday Worm is a solid mid-game resource farm. It hands out Parsteel, Tritanium, and Dilithium across a wide level band, so you can grind it for whichever material your base needs, and the higher spawns give decent ship XP. It carries no special ability or weakness to plan around, which makes it a low-stress target. Match your warp to the level you want, bring the hull that counters the variant on the map, and it goes down fast.
