Utility components

Utility components are devices that can be installed on military ships to enhance their defensive capabilities and thus increase their survivability in combat against enemies.

Defenses

Small, Medium, and large utility components increase the durability of a ship by providing extra hit points. These come in three forms: shields, armor, and hull.

Shields

Shields form the first layer of hit points of a ship.

Pros	Cons
Effective against most energy weapons. Inherent regeneration makes them sustainable out-of-the-box for operations away from base. Cheaper  Alloys cost than armor.	Vulnerable to kinetic weapons. Penetrated by guided weapons, strike craft, and some exotic energy weapons (Disruptors, Arc Emitters, and Cloud Lightning). Advanced shields require  Strategic Resource to make. Consumes power.

Armor

Armor forms the second layer of hit points of a ship.

Pros	Cons
Effective against kinetic weapons. Does not consume power. Does not require Strategic Resources to build. Since 3.6, Overall, Armor has 33% more hitpoints than Shields when tiers are equal.	Vulnerable to energy weapons. Penetrated by some exotic weapons (Disruptors, Arc Emitters, and Cloud Lightning). Lacks inherent regeneration (but can gain it through some exotic sources). Cost more  Alloys than shields.

Plating

Hull is the last layer of a ship's hit points; the ship is destroyed if the hull points reach 0. All ships have some inherent hull points; this can be increased with these Plating components.

These can be acquired either by completing the Crystalline Entity event chain, by reverse-engineering destroyed Crystalline Entities, or through searching an abandoned ship left by Caravaneers.

Pros	Cons
Few weapon weaknesses (Energy Torpedoes, Matter Disintegrators, Mining Lasers). Does not consume power. Does not cost  Alloys. The only layer that matters against bypassing weapons. More hull allows for greater chances of emergency jump, thus increasing longterm survivability. Far, far cheaper than any other source of health, point for point.	Fewer available percentage bonuses. No repeatables. Hull damage reduces ship performance. Most non standard weapons come with a bonus against hull in addition of the armor or shield bonus. Only Null Void Beam suffer from penalty against hull Lacks inherent regeneration (but can gain it through some exotic sources). Must use  Rare Crystals to build.

Component	Small		Medium		Large		Description
	Cost	Hull	Cost	Hull	Cost	Hull
Crystal-Infused Plating	0.25	65	0.50	160	1.00	390	An alloy of elements harvested from the ultra-hard Crystalline Entities lines the inner layers of this plating, improving hull integrity.
Crystal-Forged Plating	0.33	110	0.65	275	1.30	660	Modifications to the process of forging the crystalline alloy further improves its durability.

Auxiliary

Auxiliary modules go in Auxiliary slots and have a variety of effects. Regenerative Hull Tissue can be acquired by defeating various spaceborne aliens. Nanite Repair Systems can be acquired after defeating the Scavenger Bot. Orbital Trash Dispersers can be acquired via the Racket Industrial Enterprise. Enigmatic Encoders and Decoders can be acquired by defeating the Enigmatic Fortress. Marks can be obtained by gaining maximum favor with a Shroud patron. Other components are simply obtained by researching the technology with the same name.

Name	Cost	Power usage	Effects	Description
Reactor Booster	5		+20 Power Generation	Additional power generation systems increase the ship's reactor output.
Improved Reactor Booster	10		+50 Power Generation	The discovery of fusion power allows for better reactor boosters to be fitted onto our ships.
Advanced Reactor Booster	15		+100 Power Generation	The discovery of antimatter power allows for highly advanced reactor boosters that can greatly enhance ship reactors.
Afterburners	4	10	+10% Sublight Speed +5% Evasion	Afterburners provide additional combat speed for the ship.
Advanced Afterburners	6	20	+20% Sublight Speed +10% Evasion	These improved afterburners provide even more combat speed for the ship.
Reactive Armor	10 1	15	+15% Armor Hardening	Incorporating a crystal lattice in our ship's defenses provides some resistance to weapons that normally cut through armor.
Living Reactive Armor	30 1	25	+25% Armor Hardening	Threads of living metal react to incoming fire, rearranging itself to better resist penetrating weapons fire.
Regenerative Hull Tissue	20	10	+5% Daily Hull Regen +10% Daily Armor Regen	These bacteria are imprinted with the ship's structural design and will attempt to restore hull integrity should it be compromised.
Nanite Repair System	10 1	10	+15% Daily Hull Regen +20% Daily Armor Regen	A highly effective hull auto-repair system comprised of billions of microscopic nanomachines was found among the smoking remains of the Scavenger, and has been repurposed for our uses. Whether the Scavenger pilfered this system from an ancient derelict, or was originally constructed with it remains unknown.
Shield Capacitor	10 1	20	+10% Shield Hit Points	These capacitors store surplus energy which can quickly be transferred to reinforce a ship's shields.
Shield Hardener	10 1	15	+15% Shield Hardening	With these modifications, the fields generated by our shield emitters will partially deflect attacks that would otherwise bypass the shields.
Advanced Shield Hardener	30 1	25	+25% Shield Hardening	Zro particles raised to a high energy state add fluctuations to our shields that can deflect certain weapons that would otherwise easily penetrate the fields.
Auxiliary Fire-Control	10	10	+5 Chance to Hit	By installing an auxiliary fire-control system our ships can afford to make more advanced calculations, increasing accuracy.
Enigmatic Decoder	20	20	+5 Chance to Hit +5 Tracking	While producing average results in standard tests, the accuracy of Enigmatic Decoder's prediction algorithms seemingly increases as the target's flight path grows more erratic.
Enigmatic Encoder	20	20	+1 Disengagement Opportunities	The Enigmatic Encoder scrambles flight path data according to some indeterminable design before feeding it back to fleet command.
Orbital Trash Disperser	10	10	+25% Orbital Bombardment Damage	This component overwhelms planetary defensive grids with trash data by spamming them with millions of minute, high-velocity projectiles. Ships equipped with this component cause more damage during orbital bombardment.
