The U.S.S. Kelvin is a grade 4 Uncommon Federation Interceptor that unlocks at Shipyard level 42. Its job is defense: while defending, it raises the shield piercing, armor piercing, and accuracy of your whole fleet, which makes it a support hull for base and armada defense rather than a solo grinder. If you fly Federation ships, it earns its slot.
How to get the U.S.S. Kelvin
The Kelvin needs 150 blueprints to build, and the build opens once your Shipyard reaches level 42 and you have completed the required grade 4 ship research. Blueprints for it have appeared in the Federation faction store, so Federation-aligned players can gather them over time through reputation.
The build cost is 25,000,000 Tritanium, 1,600,000 Dilithium, 7,000 4★ Common Refined Crystal, and 2,450 4★ Common Refined Gas. Base build time is 150 days, before any construction-speed research or bonuses. From Operations level 55 the Kelvin becomes scrappable, so it can feed the scrapyard once you outgrow it.
U.S.S. Kelvin ability
The Kelvin’s ship ability is Inventive Strategy. When the Kelvin is defending, at the start of each round it increases the shield piercing, armor piercing, and accuracy of every ship and defense platform by 30% at level 1, scaling to 100% at level 60. Ship abilities are always active, so there is nothing to trigger.
Because the buff only fires on defense and covers your whole fleet plus defense platforms, the Kelvin reads as a base-defense and armada-defense piece. Sitting in a station defense or a defending armada, it sharpens the offense of everything around it.
U.S.S. Kelvin active abilities
The Kelvin also carries two player-unlocked abilities that sit apart from the always-on Inventive Strategy. Relentless Assault increases weapon damage against hostiles and armadas, giving the ship an offensive mode for PvE grinding. Field Repairs works out of combat: while undocked, it instantly repairs 25% of the ship’s health, which saves a trip back to dock during a long session. Both come from refits, covered below, and each is used on its own terms rather than running always. Relentless Assault also appears as a ship-specific research project, which is where its scaling comes from as you invest.
Stats and tiers
These are base values from the current game data; research, buffs, and officers raise them in play. One quirk to note: the Kelvin’s hull HP holds steady across tiers while its shield HP and cargo keep climbing, so most of its survivability growth comes from shields rather than hull.
| Tier | Warp (speed / range) | Impulse | Cargo (protected) | Shield HP | Hull HP | Health (displayed) |
|---|---|---|---|---|---|---|
| 1 | 3.9 / 85 | 98 | 40,000 (1,000) | 278,266 | 241,619 | 259,942.5 |
| 6 | 4.4 / 150 | 98 | 56,000 (1,400) | 379,729 | 241,619 | 310,674 |
| 12 | 5.0 / 210 | 98 | 96,000 (2,250) | 577,257 | 241,619 | 409,438 |
Weapons and firing pattern
Warm-up is the round a weapon first fires; cool-down is how many rounds pass between shots after that. The values below are at max tier 12.
| Weapon | Type | Shots | Warm-up | Cool-down | Damage | Crit chance | Crit damage |
|---|---|---|---|---|---|---|---|
| Weapon 1 | Kinetic | 3 | 2 | 2 | 48,626–58,349 | 10% | 150% |
| Weapon 2 | Kinetic | 3 | 2 | 2 | 48,626–58,349 | 10% | 150% |
| Weapon 3 | Energy | 2 | 1 | 1 | 31,259–37,508 | 10% | 150% |
The two kinetic weapons are the Kelvin’s main punch, firing three shots each, while the energy weapon is a lighter, faster-cycling second source.

| Ship level | Officer slots |
|---|---|
| 5 | 1 |

The Kelvin raises your officers’ attack, defense, and health stats by the same amount, stepping up a ladder as the ship gains those stats. The table shows where each step lands.
| Amount | Bonus |
|---|---|
| 700 | 40% |
| 1,400 | 80% |

U.S.S. Kelvin refits
Refits unlock the Kelvin’s extra abilities and a cosmetic skin. They cost ship shards and, in one case, a building level.
| Refit | What it does |
|---|---|
| Kelvin Relentless Assault | Unlocks the Relentless Assault ability. Needs a level 42 Armory and 60 shards. |
| Field Repairs (U.S.S. Kelvin) | Unlocks Field Repairs, which instantly repairs 25% of the ship’s health out of combat while undocked. Costs 120 shards. |
| Jem’Hadar Fighters | Unlocks the Jem’Hadar Fighter skin. |
Crew for the U.S.S. Kelvin
The Kelvin is a defensive support hull, so a defending crew wants officers that boost mitigation, shield health, or the piercing and accuracy stats its ability already leans on. For an offensive Relentless Assault build against hostiles, weapon-damage and crit officers fit better. For current top picks, see the officer tier list; the best crew shifts as the meta and your roster change.
The U.S.S. Kelvin in Star Trek
The U.S.S. Kelvin opens the 2009 Star Trek film. In 2233 it is the first Starfleet ship to meet the Narada, the Romulan mining vessel commanded by Nero that arrives through a black hole from the future. With its captain killed, first officer George Kirk takes command, orders the crew to evacuate, and then rams the Kelvin into the Narada to cover their escape. His wife gives birth to James T. Kirk during the evacuation. That sacrifice defines the film’s alternate reality, which fans named the Kelvin timeline after the ship.

Is the U.S.S. Kelvin worth it?
For a grade 4 Uncommon, the Kelvin fills a specific niche: fleet-wide defensive support that raises piercing and accuracy for everything defending alongside it. It is most useful in base defense and defending armadas, and its Relentless Assault refit gives it a side job hunting hostiles. Because it scraps from Operations 55, it stays useful through the mid game and then becomes scrap material. Federation players building reputation should grab it; others can pass. Its low cargo and defense-only ability mean it was never built to mine or grind alone, so plan to crew it for the fleet job it does best.
