Overview

- details about the POS structures (as it was causing the POS Setup and POS Warfare pages to balloon).

- need to add graphics on the right side of each area, opposite the bullet points at the start of each module's section, images should be 160x120

Control Towers

Control towers are the cornerstone of any POS setup. The choice of tower and size will determine how much fuel you use per month and how much PG/CPU you have for onlined (active) structures. Smaller towers will often have to leave modules anchored but offline until needed due to limited PG/CPU.

Amarr - first in PG, fourth in CPU
Caldari - fourth in PG, first in CPU
Gallente - third in PG, second in CPU
Minmatar - second in PG, third in CPU
Faction - reduced fuel costs, more HP, shorter anchor/online timer

At the time of writing, faction tower fuel savings require about ~~2-3 years~~ less than a year before the fuel cost savings will outweigh the cost of a faction tower over a regular tower. If you are living in a wormhole or are having logistical issues with getting enough fuel to the tower on a regular basis, faction towers may be a better choice. Faction towers have more hit points and lower anchor and online times than non-faction towers.

Note that faction towers in lo-sec / hi-sec can be a security risk as they will potentially draw unwanted attention from other players. Their high cost may be a deciding factor in whether an attack takes place.

Assembly Arrays

Assembly arrays are mounted inside the POS bubble and are used to construct modules, ships, and other items. They function similar to the manufacturing slots in NPC stations.

- need short blurb of how to use, where can the BPO be located, where can raw materials be located, where does output go

S/M/L Ship Assembly Array

There are (3) sizes of the regular ship assembly arrays. There must be a Ship Maintenance Array (SMA) within range (2500m?) of the Ship Assembly Array in order to use the production lines. When ships roll off the production lines, they are stored in the SMA. These arrays can be anchored in all security classifications (hi/lo/null).

Small (SSAA) - T1 Frigates, T1 Destroyers, T1 Fighter and Fighter Bomber Drones
Medium (MSAA) - T1 Cruisers, T1 Battlecruisers, T1 Barges, T1 Industrials
Large (LSAA) - (3) lines, T1 Battleships, T1 Freighters, T1 Industrial Command Ships

Under the old system where arrays were NPC-sold, all three sizes cost about 80M ISK. In 2010, CCP changed things so that players would have to use resources from Planetary Industry in order to construct the arrays. As of November 2013, small, medium and large arrays all sell for about 60 - 70M ISK. Therefore, the cost of the ship assembly array's size is not a major factor in the decision of which array to use.

For hi-sec use, where you have manufacturing slots available in nearby stations (which are far cheaper on a per-hour basis), the only real use of a ship assembly array is bulk storage. The SSAA and MSAA both hold 2M m3 of materials, while the LSAA holds a massive 18.5M m3. All sizes of ship assembly arrays have corporate hangar tabs to make organization easier. However, while the LSAA holds 9x more cargo then the SSAA/MSAA siblings, it only requires 4x the CPU and 3x the PG of the SSAA. So for bulk storage in a hi-sec POS, the LSAA is a very popular choice.

In order for a member to use a Ship Assembly Array as storage, you should use the tower management screen and change permissions on the xSAA module to "Corporation" or "Alliance". Do not hand out roles like "Config Starbase Equipment" or "Starbase Fuel Technician" (unless you absolutely want to).

Advanced S/M/L Ship Assembly Arrays

- T2 ship construction

- should not be used for regular ship production due to 10% increase in materials required

The advanced ship assembly arrays should only be used in w-space or deep null-sec where there are no station slots for manufacturing due to the 10% penalty in material requirements.

X-Large Ship Assembly Array

Location: Inside POS bubble
Times: 5s Anchor, 3s Online, 5s Unanchor
Fitting: 1000tf CPU, 300k MW PG
Size: 25,000 m3
Capacity: 18.5M m3
Op Range: 3000m
Slots: 3 Manufacturing (0.75x time, 1.0x materials)
Restrictions: Security level less than 0.5 (null through 0.4 sec)

Allows the construction of large ships such as T1 Battleships, T1 Carriers, T1 Dreadnoughts, T1 Freighters, T1 Industrial Command Ships and T1 Capital Industrial Ships. This array cannot be anchored in hi-sec space. Fitting requirements are identical to that of the LSAA, but are more expensive to produce with Planetary Industry. In order to directly use a ship produced by the XLSAA, you must also anchor a Ship Maintenance Array.

Capital Ship Assembly Array

Location: Inside POS bubble
Times: 30s Anchor, 10s Online, 600s Unanchor
Fitting: 2000tf CPU, 1000k MW PG
Size: 850,000 m3
Capacity: 155M m3
Op Range: 3000m
Slots: 1 Manufacturing
Restrictions: Null-sec with system sovereignty
Requires: Supercapital Construction Facilities Infrastructure Upgrade

Allows for the construction of capital ships such as Dreadnoughts, Carriers, Supercarriers, Titans. However, they are generally only used for the construction of Supercarriers and Titans as Carriers/Dreads can be constructed using the much less expensive X-Large Ship Assembly Array.

Anchoring one of these arrays will ensure negative attention from larger alliances who will suspect that you are building super-caps or titans. Very expensive to construct using Planetary Industry (the BPO alone is 500M ISK). Note that in order to move these around, you must have a ship with an 850k m3 cargo bay.

Equipment Assembly Array

Location: Inside POS bubble
Times: 5s Anchor, 3s Online, 5s Unanchor
Fitting: 150tf CPU, 90k MW PG
Size: 6250 m3
Capacity: 500k m3
Op Range: 3000m
Slots: 6 Manufacturing (0.75x time, 1.0x materials)

The Equipment Assembly Array (EAA) is used to manufacture ship modules. Slower, but more efficient then the Rapid Equipment Assembly Array.

Rapid Equipment Assembly Array

Location: Inside POS bubble
Times: 5s Anchor, 3s Online, 5s Unanchor
Fitting: 200tf CPU, 110k MW PG
Size: 6250 m3
Capacity: 500k m3
Op Range: 3000m
Slots: 5 Manufacturing (0.65x time, 1.2x materials)

The Rapid Equipment Assembly Array (REAA) is used to manufacture ship modules. Faster, but less efficient (+20% material requirement) then the Equipment Assembly Array.

Subsystem Assembly Array

Location: Inside POS bubble
Times: 5s Anchor, 5s Online, 5s Unanchor
Fitting: 500tf CPU, 200k MW PG
Size: 17,000 m3
Capacity: 2M m3
Op Range: 3000m
Slots: 3 Manufacturing (1.0x time, 1.0x materials)

The Subsystem Assembly Array (SAA) allows you to assemble Tech III hulls and advanced subsystems. However, the hulls and subsystems can only be assembled (fitted?) when docked at a station.

Storage

All storage arrays should be anchored inside the POS bubble.

Corporate Hangar Array

Location: Inside POS bubble
Times: 5s Anchor, 3s Online, 5s Unanchor
Fitting: 150tf CPU, 100k MW PG
Size: 4,000 m3
Capacity: 1.4M m3
Op Range: Within POS shield

Designed to provide floating corporate hangars at the POS tower, complete with normal corporate hangar features like divisional tabs. Because this array uses CPU, it will not be accessible if the POS is reinforced. If you need more storage, you may wish to use a LSAA instead.

Since this array will be unavailable once the POS tower enters reinforced mode that you should not store spare ammo or batteries in the array. Spare items like ammo/batteries should be stored in anchored secure containers in safe-spots, or in a nearby station.

If the array is destroyed by enemy fire (after the POS shield is gone) then the contents will drop as loot according to the standard loot rules (typically 50% of the stacks survive destruction). However, if the hangar is scooped up, taken to a station and repackaged, it may be possible to recover the contents (not extensively tested - and conflicting reports of success/failure).

Personal Hangar Array

Location: Inside POS bubble
Times: 5s Anchor, 3s Online, 5s Unanchor
Fitting: 150tf CPU, 100k MW PG
Size: 4,000 m3
Capacity: 50K m3 per individual
Op Range: Within POS shield

A large hangar structure, for easy storage of materials and modules. This hangar is designed for personal storage of moderate volume items, and each individual only has access to their own section of the storage space. As with the Corporate Hangar Array, the Personal Hangar Array uses CPU and therefore will not be accessible if the POS is reinforced. If you need more storage, you may wish to use a LSAA instead.

Ship Maintenance Array

Location: Inside POS bubble
Times: 5s Anchor, 3s Online, 5s Unanchor
Fitting: 250k MW PG (no CPU)
Size: 8,000 m3
Capacity: 20M m3 (assembled ships only)
Op Range: Within POS shield

The Ship Maintenance Array (SMA), when anchored and online, provides a place to store fitted/rigged ships. Ships can only be stored in the SMA if their cargo bay is empty of everything except for charges (ammo, scripts, crystals, probes). It can be used by up to 10 pilots simultaneously to refit their ships at the POS if they are within 3000m of the SMA. The SMA can be used/accessed even if the POS is in reinforced mode because it requires zero CPU in order to operate.

Capital Ship Maintenance Array

Location: Inside POS bubble
Times: 30s Anchor, 10s Online, 600s Unanchor
Fitting: 1000k MW PG (no CPU)
Size: 40,000 m3
Capacity: 155M m3 (assembled ships only)
Op Range: Within POS shield
Restrictions: null-sec with system sovereignty
Requires: Supercapital Construction Facilities Infrastructure Upgrade

The Capital Ship Maintenance Array (CSMA) is a larger version of the SMA only useful in player controlled null-sec. It only uses power and can be used/accessed even if the POS is reinforced.

Cynos, Jammers and Jump Bridges (no longer functional)

The below arrays were replaced by the navigation structures! And are no longer functioning! These structures were used to make travel between systems faster or to prevent enemies from generating cynosural fields.

Cynosural Generator Array

Location: 15km+ outside POS bubble
Times: 10s Anchor, 300s Online, 10s Unanchor
Fitting: 150tf CPU, 375k MW PG
Size: 4000 m3
HP: 1M Shield, 15M Armor, 100k Structure
Restrictions: null-sec with system sovereignty
Requires: Cynosural Navigation Infrastructure Upgrade
Limitations: Max of 1 per system

The Cynosural Generator Array (CGA) is a stationary cynosural field generator which allows capital ships with jump drives to jump to the POS's location from surrounding systems without the need for a cyno ship.Once anchored and onlined, the cynosural field remains active at all times. It may take a few hours until downtime until the beacon shows up for all pilots in the corp/alliance. Be warned that if you jump to a CGA, you will have to slow-boat around 15km to duck inside the POS bubble at the destination. If the POS is currently camped, this may be a fatal blunder.

Cynosural System Jammer

Location: 15km+ outside POS bubble
Times: 300s Anchor, 1800s Online, 60s Unanchor
Fitting: 750k MW PG (no CPU)
Size: 4000 m3
HP: 1M Shield, 15M Armor, 100k Structure
Restrictions: null-sec with system sovereignty
Requires: Cynosural Suppression Infrastructure Upgrade
Limitations: Max of 1 per system

Prevents the generation of normal cynosural fields (does not affect covert cynosural fields). Note that this prevents all cynosural activity, including attempts to light beacons by friendly pilots.

- Question: Does the CSJ prevent the operation of a CGA in the system or can the two co-exist?

Jump Bridge

Location: 15km+ outside of a POS bubble
Delays: Anchor: 30 sec, Online: 30 min, Unanchor: 60 sec
Fitting: CPU: 4,000 tf, PowerGrid: 750k MW
Size: 100,000 m3
HP: 1 mil Shield, 15 mil Armor, 100K Structure (0% resists)
Fuel Bay: 30,000 m3 of Liquid Ozone (75,000 units)
Operation Range: 2,500m
Restrictions: Null Sec Space with system sovereignty
Requires: Advanced Logistics Network Infrastructure Upgrade
Limitations: Max of 1 per Solar System

Used to link two Star Base in different systems to allow all ships to jump between systems without the need to setup a cynosural field. Maximum jump range is 5 Light Years. Also see Jump Bridge.

Labs, Reactors and Silos

Mobile Laboratory

Location: Inside POS bubble
Times: 5s Anchor, 3s Online, 5s Unanchor
Fitting: 500tf CPU, 100k MW PG
Size: 3000 m3
Slots: 1 Copy (0.75x time), 3 ME (0.75x time), 3 PE (0.75 time), 5 Invention (0.5x time)
Capacity: 25k m3
Range: Within POS Shield

Basic laboratory used for the research (material and time) of BPOs. Also useful for Invention due to the (5) invention slots. ME/PE research can by done on the tower by any corporation within the alliance who has a station office rented in the same system. Copy/Invention requires access to the mobile laboratory storage and thus is limited to the corporation who owns the POS tower.

In order for corporation members to use the array for invention (and copying?), you will need to change the query/take permissions using the POS tower's management screen. In that screen you can change who is able to "query" from "Starbase Fuel Technician" to "Corporation" and you will change the "take" from "Config Starbase Equipment" to "Corporation".

If a laboratory array is taken offline, any jobs that were running on that array will be paused. If the laboratory array is then unanchored, any BPOs inside the array will be destroyed. If the BPOs were kept in a station in the same system, then all research progress will be lost but the BPO will not be destroyed during the unanchor process. If the tower is still intact, you cannot unanchor a mobile lab that has items inside (you will have to put it back online, empty it out, then go back to unanchoring it).

Advanced Mobile Laboratory

Location: Inside POS bubble
Times: 5s Anchor, 3s Online, 5s Unanchor
Fitting: 600tf CPU, 120k MW PG
Size: 3000 m3
Slots: 3 Copy (0.65x time), 2 ME (0.75x time), 2 Invention (0.5x time)
Capacity: 25k m3
Range: Within POS Shield

Mostly used when you need a lot of copy slots for T2 production. Most POS towers will run a mix of AMLs and MLs to balance out the ME/PE/copy/invention slots to meet user's needs. For instance, a mix of five AMLs and six MLs will give 28 ME / 12 PE / 21 copy / 40 invention slots.

Moon Harvesting Array

Moon Harvesting Arrays are structures for Moon Mining. When set up correctly, they will extract raw materials from the moon you starbase is Anchored at. Depending on your configuration, the Harvester Array will pass the materials onto a Reactor Array for reaction or will store them in a Silo.

Location: Inside POS bubble
Times: 5s Anchor, 3s Online, 5s Unanchor
Fitting: 500tf CPU, 10k MW PG
Size: 4000 m3

- low/null sec moon mining structures

Refining Arrays

Refining Arrays (better known as Mobile Refineries) allow you to reprocess ore at a starbase. You must load the Refinery with the ore (only one ore type is allowed in the refinery at a time). Once loaded, right-click the Refinery and start the process. Unlike stations, the process is not immediate. You have to wait between 1 and 3 hours before the contents of the Refinery are changed into minerals.

There are three types of Mobile Refinery:

Refining Array

Location: Inside POS Bubble
Times: 5s Anchor, 3s Online, 5s Unanchor
Fitting: 700tf CPU, 100K MW PG
Size: 4,000 m3
35% yield

Restricted to Security <0.4
20K Shield | 20K Armor | 10K Structure

Medium Intensive Refining Array

Location: Inside POS Bubble
Times: 5s Anchor, 3s Online, 5s Unanchor
Fitting: 2,000tf CPU, 375K MW PG
Size: 4,000 m3
75% yield
Cycle time: 1.5 Hours
Capacity: 25,000 m3
Restricted to Security <0.4
20K Shield | 20K Armor | 10K Structure

Intensive Refining Array

Location: Inside POS Bubble
Times: 5s Anchor, 3s Online, 5s Unanchor
Fitting: 4,000tf CPU, 750K MW PG
Size: 6,000 m3
75% yield
Cycle time: 3 hour
Capacity: 200,000 m3
Restricted to Security <0.4
20K Shield | 20K Armor | 10K Structure

Note that the Refining Arrays refining yield efficiency does not apply to ice ores, which are always refined at the maximum efficiency the operator is capable of. Also, if the array's control tower runs out of fuel while the array is in the middle of a processing operation, the materials being refined will be irrevocably lost.

For further information see POS Refining.

Silos

Silos are used to store Raw Materials, Processed Materials, Advanced Materials or Minerals. A Silo can only hold one type of material at a time and must be put offline to change type or to empty it.

Silo varieties:

Biochemical Silo

Specialized container designed to store and handle gas clouds.
Location: Inside POS Shield

Fitting: 250tf CPU, 50K MW PG
Size: 4,000 m3
Capacity: 40,000 m3

Silo

Used to store or provide resources.
Location: Inside POS Shield
Times: 5s Anchor, 3s Online, 5s Unanchor
Fitting: 500tf CPU, 50K MW PG
Size: 4,000 m3
Capacity: 20,000 m3

Coupling Array

Coupling Arrays act as an intermediary holding pipe between two structures. Take for instance the Moon Harvesting Array and Silo. Since you must offline your Silo before emptying it, you may lose a cycle of raw materials. By placing a Coupling Array between the Harvester and Silo, you can safely offline the Silo while you empty it and any Raw Materials that arrive will temporarily be stored in the Coupler Array.

The Coupling Array is also useful for when the Harvesters and a Reactor are running/processing at different speeds. For instance, two Harvesters may produce 100 units each an hour. The Reactor may only be able to process the said units every 2 hours. This leaves you with a surplus of 100 units that will be lost in the process. A Coupling Array acts as a buffer to temporarily hold the surplus materials until the Reactor is free.

Location: Inside POS Shield

Defensive Structures

Shield Hardening Arrays

Location: Inside POS Bubble
Times: 5s Anchor, 120s Online, 5s Unanchor
Fitting: 250tf CPU, 150k MW PG
Size: 4000 m3
Types: 1 for each resist (EMP, EXP, KIN, THE)
Strength: 25% (but with stacking penalties)

Shield hardeners come in four types, one for each resist, and should be mounted inside the POS bubble. They are named Ballistic Deflection Array (KIN), Explosion Dampening Array (EXP), Heat Dissipation Array (THE), and Photon Scattering Array (EMP). Since shield hardening arrays are inside the bubble, they cannot be targeted until the tower is destroyed. However, they become inactive once the tower enters reinforced mode.

For details about how many hardeners to anchor/online, see Shield Hardening on the POS Warfare page.

Sensor Dampening Battery

Location: 5km+ outside POS bubble
Times: 5s Anchor, 120s Online, 5s Unanchor
Fitting: 25tf CPU, 12.5k MW PG
Size: 4000 m3
HP: 100k Shield, 1.5M Armor, 100k Structure
Range: 300km Activation, 150km Optimal, 150km Falloff

The Sensor Dampening Battery cuts the target's scan resolution and targeting range in half. It has very low fitting requirements and can force an enemy to come closer to POS weapons instead of being able to sit at long range and snipe. Just like any other module that targets enemy ships, it must be mounted outside the POS bubble and can be attacked by enemy ships before the POS tower is destroyed.

There are two schools of thought with regards to Sensor Dampening Batteries. One is that they are completely unnecessary if you have faction ECM batteries with their 200km optimal + 100km falloff range. The other school of thought is that a few Sensor Dampening Batteries never hurt and could be used to good effect by POS gunners. Either way, you will generally not need more then a small handful (as few as 1-3, probably no more then 6) of these and your tower defenses will be fine without any at all (as long as you have ECM).

Note: Dreads are immune to sensor dampening in siege mode and carriers are immune if in triage mode.

ECM Batteries

Location: 5km+ outside POS bubble
Times: 5s Anchor, 120s Online, 5s Unanchor
Fitting: 50tf CPU, 25k MW PG
Size: 4000 m3
HP: 100k Shield, 1.5M Armor, 100k Structure
Range: 300km Activation, 200km Optimal, 100km Falloff
Jam Strength: 45 for primary, 15 for secondaries

The four ECM batteries are Ion Field Projection Battery (MAGNET, Gallente), Phase Inversion Battery (LADAR, Minmatar), Spatial Destabilization Battery (GRAV, Caldari) and White Noise Generation Battery (RADAR, Amarr).

Faction versions of these modules are recommended but will cost about 6x-10x more. A regular faction ECM battery (Gurista) will have 51 primary / 17 secondary jam strength and the advanced faction ECM battery (Dread Gurista) will have 76 primary / 25 secondary jam strength. The Dread Gurista versions are worth the cost if you expect hostiles at the tower. With their increased jam strength, even ECCM-fitted battleships will constantly lose their locks and have to retarget.

See POS Warfare (ECM section) for more details on proper use of ECM.

There are two major reasons why missile / torpedo batteries are rarely used. First off is the travel time of the missiles, the second is that they are the only offensive batteries that use CPU power. Due to this use of CPU power, once the POS tower goes into reinforced mode, all missile batteries will go offline and be worthless. The only way to put the missile batteries back online is to wait for the POS to come out of reinforced mode, repair the shields up to 50% or higher, and then manually put each missile battery back online.

Projectile batteries are popular, even on non-Minmatar towers because their damage can be tuned with the appropriate choice of ammunition. Good ammunition to use with projectile batteries are Fusion (EXP/KIN), Phased Plasma (THE/KIN) and EMP (EMP/EXP/KIN) or Titanium Sabot (KIN/EXP). The long-range ammunition versions are not needed and will do less damage. Faction ammunition is a popular choice for the increased alpha / DPS.

Scrams, Neuts and Webs

- blurb about scrams, neuts and webs

Energy Neutralizing Battery

Location: 5km+ outside POS bubble
Times: 5s Anchor, 120s Online, 5s Unanchor
Fitting: 25tf CPU, 350k MW PG
Size: 4000 m3
HP: 100k Shield, 1.5M Armor, 100k Structure
Range: 300km Activation, 250km Max Range

Neutralizes up to 1000 GJ of capacitor energy every 10 seconds. Very heavy powergrid requirements, not recommended for small or medium towers. In comparison, most battleships have around 4,000 to 6,000 GJ of capacitor with 10-30 GJ/s recharge. These weapons are most often used against enemy carriers in triage mode. Rarely used in hi-sec tower defense due to the heavy fitting requirements and it is generally better to employ additional ECM batteries.

Stasis Webification Battery

Location: 5km+ outside POS bubble
Times: 5s Anchor, 120s Online, 5s Unanchor
Fitting: 25tf CPU, 50k MW PG
Size: 4000 m3
HP: 100k Shield, 1.5M Armor, 100k Structure
Range: 300km Activation, 150km Max Range

Turns fast-moving targets into slow-moving targets with a -75% penalty to the web target's velocity. Works on a 10 second cycle. In generally, you should have at least a few of these to keep interceptor pilots from draining your weapon batteries of their ammo by speed-tanking.

Warp Disruption Battery

Location: 5km+ outside POS bubble
Times: 5s Anchor, 120s Online, 5s Unanchor
Fitting: 50tf CPU, 100k MW PG
Size: 4000 m3
HP: 100k Shield, 1.5M Armor, 100k Structure
Range: 300km Activation, 150km Max Range
Strength: 3 points

Warp disruption batteries are long range warp scramblers with 3 points of strength. Works on a 10 second cycle. Best used when you have POS gunners to tackle a particular ship and then focus all weapons on that ship while they are trapped. Even with the heavy fitting requirements, you will want to anchor 2 of these on a large tower.

Warp Scrambling Battery

Location: 5km+ outside POS bubble
Times: 5s Anchor, 120s Online, 5s Unanchor
Fitting: 25tf CPU, 25k MW PG
Size: 4000 m3
HP: 100k Shield, 1.5M Armor, 100k Structure
Range: 100km Activation, 75km Max Range
Strength: 6 points

Warp scrambling batteries are short range warp scramblers with 6 points of strength. Compared to their big brothers, they are a lot easier to fit (1/2 the CPU and 1/4 the PG). Works on a 10 second cycle.
