Hullmod

Up to date for latest version, 0.97a.

Hullmods are special modifications applied to ships. Hullmods can provide a variety of effects, ranging from simply increasing stats like armor or weapon range to completely overhauling how a ship functions. Some hullmods are inherent to a particular ship hull and cannot be added or removed, while others can be installed and uninstalled for Ordnance Point cost.

At the start of the game, the following hullmods are available for installation: Additional Berthing, Armored Weapon Mounts, Auxiliary Fuel Tanks, Auxiliary Thrusters, Blast Doors, Dedicated Targeting Core, Expanded Cargo Holds, Flux Coil Adjunct, Flux Distributor, Hardened Subsystems, Reinforced Bulkheads, Militarized Subsystems, Safety Overrides, and Unstable Injector. New hullmods can be obtained by using "modspecs" that can be purchased at markets or found in salvage. Modspecs that you already have unlocked typically do not appear again. Some skills also unlock hullmods, although most of them can be learned though a modspec.

Once a hullmod has been unlocked it can be installed on any number of player ships. It's possible to have a ship with an installed hullmod that you do not have unlocked (for example, starting ships often have some) - if it's uninstalled, it will not be possible to install it again.

Logistics hullmods

Unlike regular hullmods, logistic hullmods can only be added and removed while docked. They usually affect non-combat stats like cargo capacity or maximum burn. A ship is normally limited to two logistics hullmods.

Damage hullmods

Example of price difference between Mules with different amounts of d-mods.

Damage hullmods (commonly known as D-mods) represent serious long-term damage to a ship, and are added when a ship is recovered after battle. They may be removed by restoring the ship in a dock at a planet or station, for a high credit cost. Ships with damage mods cost fewer supplies to deploy.

Many ships sold at the shop will have D-mods. Ships with D-mods are cheaper; the difference is particularly large for the first D-mod.

Ill-Advised Modifications and Special Modifications are also considered D-mods, but do not affect recovery cost and cannot be added after the ship recovery. They are instead similar to built-in mods, appearing on specific hulls. They can be removed by restoring the ship, but not with Hull Restoration skill.

Damage mods are shown as orange bars on the ship icon. A ship can have up to 5 D-mods.

Built-in

Many ship hulls come with hullmods built into them from the start. A built-in hullmod doesn't cost any OP and doesn't count against the logistics hullmod limit. A common example is Civilian-grade Hull, which is built into numerous ships. Some built-in mods are regular hullmods (for example, Venture has built-in Surveying Equipment, which can be installed on any ship), while others are unique to the hulls they are built into, such as Advanced Targeting Core or Salvage Gantry. Some built-in hullmods are disadvantageous, representing a specific limitation of a ship class, such as Ablative Armor or Delicate Machinery.

S-mods

A regular hullmod can be built-in for 1 SP, turning it into an S-mod. S-mods are permanent and do not cost any OP. Additionally, many hullmods provide an additional effect when turned into an S-mod. Cheaper hullmods and logistics hullmods usually provide a bonus, while more expensive s-mods usually come with a disadvantage. Your ships are normally limited to two S-mods, increasing to three with Best of the Best. This use of story points grants bonus XP depending on the size of the ship, smaller ships give more.

Built-in hullmods with bonus effects can be enhanced instead. This also costs 1 SP, always grants 100% bonus XP, and does not count against the maximum limit.

S-mods are shown as green bars on the ship icon.

Certain NPC fleets also have S-modded ships. These are fairly rare and only appear in specific conditions - there are currently no randomly-generated fleets with S-modded ships.
