Defensive Systems

Defensive Systems covers all technologies related to ship survivability, including armour, shields, cloaking, thermal reduction, and damage control. These technologies determine how well a ship can avoid detection, absorb damage, repair itself, and mitigate incoming threats.

Damage Control

Damage Control systems allow ships to repair internal damage without requiring a shipyard.

Type	Damage Control	Improved Damage Control	Advanced Damage Control	Commercial Damage Control
Repair Capacity (HS)	4	8	12	4
RP Cost	5,000	15,000	45,000	5,000

Armour

Armour protects the hull of ships from incoming damage. Stronger armour provides more protection per hull space.

Armour (Tier 0–5)

Type	Structural Shell	Conventional Steel Armour	Conventional Composite Armour	Conventional Advanced Composite Armour	Duranium Armour	High Density Duranium Armour
Str/HS	0	1	2	3	4	6
RP Cost	50	125	250	375	500	2,500

Armour (Tier 6+)

Type	Composite Armour	Ceramic Composite Armour	Laminate Composite Armour	Compressed Carbon Armour	Biphase Carbide Armour	Crystalline Composite Armour	Superdense Armour	Bonded Superdense Armour	Coherent Superdense Armour	Collapsium Armour
Str/HS	8	10	12	15	18	21	25	30	36	45
RP Cost	5,000	10,000	20,000	40,000	80,000	150,000	300,000	600,000	1,250,000	2,500,000

Shield Technology

Shields absorb incoming energy damage and regenerate over time. Higher-level shields provide more protection for the same generator size.

Shield Type

Type	Alpha	Beta	Gamma	Delta	Epsilon	Theta	Xi	Sigma	Tau	Psi	Omega	Omicron
Strength Multiplier	1.0	1.5	2.0	2.5	3.0	4.0	5.0	8.0	10.0	12.0	15.0	6.0
RP Cost	1,000	2,000	4,000	8,000	15,000	30,000	60,000	250,000	500,000	1,000,000	2,000,000	120,000

Shield Regeneration Rate

Regeneration amount per 300 seconds.

Rate	1	1.5	2	2.5	3	4	5	6	8	10	12	15
RP Cost	1,000	2,000	4,000	8,000	15,000	30,000	60,000	125,000	250,000	500,000	1,000,000	2,000,000

Maximum Shield Generator Size

Maximum hull space (HS) for shield generators.

Max Size (HS)	10	12	15	20	25	32	40	50
RP Cost	1,000	2,000	4,000	8,000	15,000	30,000	60,000	120,000

Cloaking Technology

Cloaking reduces sensor detection range and determines the minimum size and efficiency of cloaking devices.

Cloaking Theory

Technology	RP Cost	Description
Cloaking Theory	10,000	The prerequisite technology for all cloaking systems and related advancements.

Cloaking Efficiency

Higher efficiency allows a cloak of a given size to be mounted on a larger ship.

Efficiency	3	4	5	6	8	10	12	15
RP Cost	4,000	8,000	15,000	30,000	60,000	125,000	250,000	500,000

Cloak Sensor Reduction

Reduces the range at which hostile sensors can detect the ship.

Reduction	75%	80%	85%	90%	93%	95%	97%	98%	99%	99.5%
Multiplier	0.25	0.20	0.15	0.10	0.07	0.05	0.03	0.02	0.01	0.005
RP Cost	4,000	8,000	15,000	30,000	60,000	125,000	250,000	500,000	1,000,000	2,000,000

Minimum Cloak Size

Minimum hull space (HS) for cloak components.

Size (HS)	25	20	15	12	10	8	6	4	3	2

Thermal Reduction

Reduces thermal signature of engines, making ships harder to detect with thermal sensors.

Signature	100%	75%	50%	35%	24%	16%	12%	8%	6%	4%	3%	2%	1%
Multiplier	1.00	0.75	0.50	0.35	0.24	0.16	0.12	0.08	0.06	0.04	0.03	0.02	0.01
