Power Cores: Each Power Factor (PF) produces 1 Energy Unit (EU) per round. A system that requires a number of PF to function, in essence, requires that many EU per round. PF are assigned from the Power Core; EU can be generated through assigned PF or allocated from Auxiliary.
Impulse Engines: Multiple impulse engines can be linked together into a single large bank of thrusters. Impulse power provides the same acceleration and cruising speed as the Induction Engine.
Warp Drive: Traveling at warp speed requires 1 EU per
day per warp factor, either from assigned PFs or with EU drawn from Auxiliary.
Warp 1 is the speed of light, and each warp factor increases geometrically.
| Warp 1 | 0.0027 light years/day | Warp 4 | 0.1752 light years/day | Warp 7 | 0.9391 light years/day |
| Warp 2 | 0.0219 light years/day | Warp 5 | 0.3422 light years/day | Warp 8 | 1.4018 light years/day |
| Warp 3 | 0.0739 light years/day | Warp 6 | 0.5914 light years/day | Warp 9 | 1.9959 light years/day |
Deflector Shields: Each Shield Emitter protects up to
20 durability worth of adjacent compartments. Each EU allocated to a Shield
Emitter generates 1 Ablative point. The total accrued Ablative points among
all Shield Emitters on the ship can never exceed the ship’s total durability.
Energy allocated to shields cannot be taken back, and all energy is lost
when shields are lowered. Deflector shields function like the Ablative
Shield, except that secondary damage is not blocked. Additionally, each
round a System Operation-defenses skill check can be made to rotate shield
harmonics (+1/+2/+3 attack penalty for the rest of that round).

| Klingon Torpedo | 8 | 4 | +1 | 1 | 2 / 5 / 10 | d8+1w / d6+1m / d8+1m | En (g) |
Phasers (Phased-energy rectification): Powering up a Phaser Array requires two assigned PF, and making an attack requires additional EU—each EU spent from Auxiliary adds +1 to the damage roll (at least 1 EU must always be spent). Phaser Arrays vary in size (2, 4, 6, 8, or 10 durability), and the number of EU that can be spent on any one phaser firing cannot exceed twice the durability of the Phaser Array. Capital ships can have multiple Phaser Arrays, but all of them still draw energy from Auxiliary.
Photon Torpedoes: Ships may have multiple torpedo tubes, and each tube is capable of independent firing each round. Torpedoes are generally En (e) weapons, but the torpedoes can be re-programmed to function as En (g) or other specialty attacks. Firing a torpedo requires 1 EU from Auxiliary.
