Weaponry would also have a higher chance of missing without a Sensor Array.
Ships also need cooling systems for energy weapons, reactors, thrusters, and tractor beams.
Missiles would have no fire chance, Nor would cannons.
Cannon rounds would most likely gain speed over time (because there is no limit to speed).
There would be no range limit for projectile weapons (as although lasers would fade away due to energy being lost, cannon rounds would keep going)
Cannon Rounds wouldn't be absorbed by Shields, they would either be deflected or would just ding off
Small Lasers and Electrobolts would have a hilariously short range due to heat loss
Laser or Ion Weaponry can overheat, meaning it would take some time to cool down
Thrusters wouldn't need as much energy to consistently move a ship due to there being little to no friction in space
Ships could reach insane speeds with only a few thrusters as long as they have enough room
FTL travel would either be much faster or much longer then how it is ingame
Heading in a Sun location would result in an instant destruction of your ship due to the insane heat
Cannons could have varying shell-types and could probably fire round or pointed shells.
Cannons would need near-constant barrel or Gun changes due to the inability to remove heat from the barrel without cooling systems
PD would be completely useless as they would be unable to effectively hit a missile or be able to damage armor/weaponry
Crew could die when entering a reactor (Going of the premonition that the reactors are nuclear) without proper equipment
Flak Guns would need special ammunition, due to them using timed-fuse rounds
Ammunition would take longer to carry, but would be quicker to load into guns (due to the weight of the rounds and them being loaded directly into the gun instead of waiting for them to auto-load)
Gun Cradles (think that's the term) would be much, much bigger and would be position farther back into the turrets of the Heavy Cannon and Standard Cannon.
Engine Rooms would have to be cooled in order for crew to operate at maximum efficiency
Engine Rooms could also speed up turret traverse for Prisms, Cannons/Heavy Cannons, Heavy and normal Laser Cannons, Electrobolts, and Tractor Beams
If an Engine Room is damaged, the Buffs are completely removed until the engine room is repaired
For Turreted Weapons, if the engine room is destroyed, the turrets are locked in place for a bit before they return to normal traverse speed (without buff)
Ships would have to have a constant coolant supply, otherwise, the ship will be highly dangerous to operate
Ammunition-based (Flak, Heavy/Standard Cannon, Railgun) Weaponry can be upgraded to have auto-loaders
Cannons can be upgraded to have bore-barrels, which can increase AP capabilities
Cannons do not require muzzle-brakes
Cannons need specialized barrels for their explosive propellant to work, otherwise, the cannons cannot fire
Corridors can be upgraded to either be armored, have fire extinguishers built-in, or have piping systems that automatically funnel vital resources throughout the ship
I think some of these could work
