High Performance Jump Drive Power Plants

If a Starship has a High Performance Power Plant to power the Jump Drive, this
power plant should be able to be used for other uses as well.

It makes no sense to me that in High Guard, Weapons Systems has to have
corresponding Power Plant and Fuel, as if The Power Plant and Weapon System was
going to to in operation continuously.

There should be a general purpose allocation of power and fuel consumption as
various drives/weapons systems are used.
