The Separatist D3 Class is a grade 3 Uncommon Klingon Interceptor built around one job: hitting Romulan ships harder than most vessels in its price range. Its Romulan Crusher ability adds weapon damage against Romulan hulls, and a built-in cloak lets it pick its fights. You unlock the build at Shipyard level 26. For a mid-grade Interceptor, it works as a focused Romulan hunter rather than an all-rounder.
How to get the Separatist D3 Class
Building the Separatist D3 Class needs 80 blueprints and a Shipyard at level 26. Blueprints for it have appeared in the in-game event store, so it tends to show up during event rotations rather than as a standard shipyard unlock. Once you have the blueprints, the build cost is 1,150,000 Tritanium, 38,500 Dilithium, and 500 3★ Common Refined Crystal, and the build takes 12 days and 22 hours.
Separatist D3 Class ability
The ship ability is Romulan Crusher. It increases the D3’s weapon damage against Romulan ships, starting at 30% at level 1 and climbing to 120% at level 45. Ship abilities are always active, so the bonus applies automatically whenever you fight a Romulan-faction target. That makes the Separatist D3 a specialist: against Romulan hostiles and Romulan hulls it hits well above an ordinary grade 3 Interceptor, while against other factions it performs like a stock ship of its class.
Separatist D3 Class active ability
The Separatist D3 also carries a player-triggered ability, Ship Cloaking. When you activate it, the ship becomes cloaked and stays hidden until the cloak’s duration runs out, you enter combat, start mining, or dock at a station. It runs on a cooldown that shortens as the ship tiers up. Use it to slip past hostiles, reposition near a target, or open an attack on your own terms instead of being spotted on the approach. Because the cloak drops the moment you engage, mine, or dock, treat it as a positioning tool rather than a defensive shield; its value is deciding when and where a fight starts.
Stats and tiers
Base values come from the current game data; research, buffs, and officers raise them in play.
| Tier | Warp (speed / range) | Impulse | Cargo (protected) | Shield HP | Hull HP | Health (displayed) |
|---|---|---|---|---|---|---|
| 1 | 2.5 / 24 | 115 | 10,000 (230) | 5,460 | 5,460 | 5,460 |
| 5 | 2.9 / 33 | 115 | 22,970 (280) | 5,460 | 5,460 | 5,460 |
| 9 | 3.3 / 50 | 115 | 60,000 (450) | 5,460 | 5,460 | 5,460 |
Cargo grows a lot from tier 1 to tier 9, but the D3 is a warship, not a hauler, so that space matters more for surviving a raid than for mining runs.
Weapons and firing pattern
Warm-up is the round a weapon first fires; cool-down is the number of rounds between shots after that. Values below are at max tier 9.
| Weapon | Type | Shots | Warm-up | Cool-down | Damage | Crit chance | Crit damage |
|---|---|---|---|---|---|---|---|
| Weapon 1 | Kinetic | 2 | 1 | 2 | 11,756–14,369 | 15% | 110% |
| Weapon 2 | Kinetic | 2 | 2 | 2 | 11,756–14,369 | 15% | 110% |
Both weapons are kinetic, which is the damage Romulan Crusher multiplies against Romulan targets. Weapon 1 fires a round earlier than Weapon 2, so the D3 opens with a single volley and then settles into a two-gun rhythm.
Crew slots and officer bonus
The D3 opens officer seats as it levels, reaching a full bridge of five at ship level 40.
| Ship level | Officer slots |
|---|---|
| 5 | 1 |
| 10 | 2 |
| 20 | 3 |
| 30 | 4 |
| 40 | 5 |
The ship also boosts the officers riding it, stepping up a ladder as its combined officer stats climb. On the D3 the attack, defense, and health bonuses are identical at every step, so a single figure covers all three.
| Amount | Bonus (attack / defense / health) |
|---|---|
| 120 | 30% |
| 240 | 60% |
| 390 | 90% |
| 540 | 120% |
| 720 | 150% |
| 960 | 180% |
| 1,320 | 210% |
| 1,800 | 240% |
| 2,400 | 270% |
| 3,600 | 300% |
Crew for the Separatist D3 Class
Because the D3’s edge is the Romulan damage bonus, crew it for offense. A captain that raises weapon or kinetic damage, or lifts critical-hit chance and damage, turns the always-on bonus into real burst. Fill the bridge with officers that add attack or crit, and lean on the ship hardest when your target list is Romulan hostiles or Romulan-faction players. For current top picks, check the Officer Tier List, and remember that the best crews shift as the meta and new officers arrive.
Best Separatist D3 Class crews

Captain: Yuki Sulu
Officer: Alexander Marcus
Officer: Liviana Charvanek
A great crew to hunt battleships with. Below deck focus crew on health.
Captain: James T. Kirk
Officer: Spock
Officer: Leonard McCoy
A good starter crew for the Separatist D3. Below deck crew should focus on defense.
Separatist D3 Class PVE Crews
Captain: Christopher Pike

Officer: T’Laan
A good crew when battling against interceptors.
Captain: Jean-Luc Picard

The Separatist D3 Class in Star Trek
The Separatist D3 is a Star Trek Fleet Command design rather than a ship from the shows. Its backstory belongs to the game’s Klingon storyline: House Antaak breaks away from the Klingon Empire during a Separatist movement and turns the D3, once a support craft flying alongside the heavier B’Rel, into a frontline warship with heavier disruptors and reinforced tritanium armor. The D3 label follows the Klingon habit of numbering warship classes, but the vessel and House Antaak’s Separatist arc are the game’s own invention, not screen canon.

Is the Separatist D3 Class worth it?
For a grade 3 Uncommon, the Separatist D3 earns its slot if you spend real time against Romulans, whether that is faction hostiles for reputation and loot or Romulan hulls in PvP. At grade 3 it lands in the early-to-mid game, around the point where many players are grinding Romulan reputation, which is when the Romulan Crusher bonus pays off most. Outside that matchup it is an ordinary mid-tier Interceptor, so treat it as a situational hunter rather than a daily driver. One planning note: the D3 cannot be scrapped, so it will never feed parts into a later ship. Build it because you want the Romulan edge, not as a stepping stone.
