Build:Impulse Engines

7.2 Impulse Engine Power

As described previously, a ship’s impulse engines also provide power for other systems. This power is cumulative with power generated by the warp engines.

Fission Power Systems

Fission reactors onboard vessels provide power to the ship's general systems, as well as the propulsion plants for which they were generally developed. The value is established as 4 Power per set of fission reactors, as discussed in 6.2.2 Fission Propulsion Systems. Additional fission reactor sets can be added to provide additional power.

Fusion Power Systems/Atomic Piles

Fusion reactors onboard vessels provide power to the ship's general systems, as well as the propulsion plants for which they were generally developed. The value varies per the table associated with 6.2.3 Fusion Propulsion Systems/Atomic Piles. Additional fusion reactor sets can be added to provide additional power.

Fusion Propulsion

Engine	Power
Type I	1.5
Type II	1.5
Type III	2
Type IV	2
Type V	2.5
Type VI	2.5

Main Impulse Engines

The first two components (of four) in an impulse propulsion system (IPS) generate and accelerate energy for the impulse engine set to which they are installed, but also provide power to the ship's general systems. The output value varies per the table associated with 6.2.4 Main Impulse Engines. Fusion reactors are installed as auxiliary generators when the ship needs more operational power than its warp core and impulse reactors can spare after supporting propulsion.
