Understanding Core Systems & Damage

OVERVIEW
The core systems of any crewed spacecraft are divided into three umbrella categories: hull structure, electrical grid, and environmentals. Each of these systems is responsible for a major aspect of the ship's operation, and should never be made vulnerable to the enemy if at all possible.  Damage to any of the ship's core functions will result in significant repercussions, and conducting reparations is rarely an efficient use of time.

HULL STRUCTURE
The hull is the ship's backbone, and its integrity is paramount for survival in space.  Damage accrued in battle against enemy combatants will reduce the hull's stability proportional to the offensive rating of the weapon.  Reparations can be made over time in space (max 10 steps per day), or immediately at a supply dock, at the cost of 2% of the system's base price per step (20 hitpoints).


STABLE (90-100%)
The ship's hull structure is at the upper limit of its integrity and is functioning optimally.  In this state all core systems are shielded from direct attack.

DAMAGED (50-89%)
The ship's hull structure is below integrity but still largely intact.  In this state the ship's core systems are vulnerable to attack, with a 20% chance of system damage per strike.

HEAVILY DAMAGED (20-49%)
The ship's hull structure has been heavily weakened and further hostilities should be avoided at all costs.  In this state the ship's core systems are very vulnerable to attack, with a 50% chance of system damage per strike.

SEVERELY DAMAGED (1-19%)
The ship's hull structure is dangerously unstable and on the verge of collapse.  In this state the ship's core systems are completely vulnerable, with a 90% chance of system damage per strike.

DESTROYED (0%)
The ship's hull structure has reached critical system failure, and can no longer function.

ELECTRICAL GRID
The electrical grid is the largest and most comprehensive system aboard any spacecraft, and is ultimately responsible for facilitating every aspect of the ship's physical operation.  Under optimal circumstances the ship's powerplant and mainframe are lightly shielded from enemy attack, but damage to the ship's hull structure will expose her core systems to damage as well.  

Each weapon strike on a vulnerable hull has a chance to reduce the stability of the ship's electrical grid. Reparations can be made over time in space (max 10 steps per day), or immediately at a supply dock, at the cost of 2% of the system's base price per step (20 hitpoints).


STABLE (100-90%)
The ship's electrical grid is unhindered and functioning at peak performance.  In this state the ship is able use all power produced and her electromagnetic engines operate at maximum efficiency.

DAMAGED (50-89%)
The ship's electrical grid is disrupted but largely intact.  In this state the powerplant has been slightly dialed down to prevent overheat due to damaged radiators, resulting in a 20% reduction in useful power.  Consequentially, the efficiency of the ship's electromagnetic engines has also been reduced by 20%.

HEAVILY DAMAGED (20-49%)
The ship's electrical grid has been compromised in multiple critical areas and the powerplant has begun to fluctuate. In this state the powerplant has been greatly dialed down to prevent overheat due to coolant loss, damaged radiators, and short circuits, resulting in a 50% reduction in useful power.  The efficiency of the ship's electromagnetic engines has also been reduced by 50%, but no communication blockages save for transient interference yet exist.

SEVERELY DAMAGED (1-19%)
The ship's primary powerplant has been compromised and automated safeguards have tripped non-essential subsystems.  In this state power distribution to core functions is now temporarily sustained by failsafe capacitors, resulting in a 90% reduction in useful power.  The efficiency of the ship's electromagnetic engines has been reduced by 100% and assets in remote territories cannot be contacted.

DESTROYED (0%)
The ship's electrical grid has been fully compromised and her electromagnetic engines rendered inoperable.  Assets outside of the ship cannot be contacted.

ENVIRONMENTALS
Environmental control and life support systems are essential for the survival of a living crew, and are responsible for the storage, provision, and recycling of crew supplies during operation. Under optimal circumstances the ship's environmentals are lightly shielded from enemy attack, but damage to the ship's hull structure will expose her core systems to damage as well.  

Each weapon strike on a vulnerable hull has a chance to reduce the stability of the ship's environmentals. Reparations can be made over time in space (max 10 steps per day), or immediately at a supply dock, at the cost of 2% of the system's base price per step (20 hitpoints).


STABLE (90-100%)
The ship's environmentals are unhindered and functioning optimally.  In this state the ship's company are conditioned to work at peak performance and all proficiency gained may be put to use.

DAMAGED (50-89%)
The ship's environmentals are disrupted but largely intact.  In this state the ship's company are rationing to conserve utilities but are still fit for duty.  Unallocated proficiency is lost at a rate of 1 per day.

HEAVILY DAMAGED (20-49%)
The ship's environmentals are no longer reliable and her company are strictly rationed.  In this state several shifts have been suspended to conserve manpower and crew remain partially suited whenever possible, resulting in an unallocated proficiency loss of 2 per day.

SEVERELY DAMAGED (1-19%)
The ship's environmentals have been largely compromised and backup procedures have been implemented.  In this state all non-essential personnel have been suspended to rest, rations are distributed on a triage basis, and all crew remain fully suited to protect against low atmospheric pressure, poor air quality, and solar radiation, resulting in a unallocated proficiency loss of 3 per day and the temporary inability to gain further unallocated proficiency (excluding flagship kills).

DESTROYED (0%)
The ship's environmentals have been fully compromised and her company must survive in the absence of suitable atmospherics, provisions, and hygienic or medical utilities, resulting in an unallocated proficiency loss of 4 per day and in the temporary inability to gain further proficiency of any kind, trained or unallocated (excluding flagship kills).
