Point Defense Module OverviewEdit
Point defense (or PD) refers to auto-fire weapon systems meant to intercept and destroy incoming enemy ordnance before it can harm the ship. There are two types of such ordnance in the game: Missiles and Fighters. With the sole exception of Extreme Counterattack, these are the only types of weapons that PD-modules defend against.
While it is possible to mount all of these modules on a ship, that is not a recommended approach. Initially you have access to the basic Anti-Aircraft Cannon, which works for both anti-missile and anti-fighter defense even at a lower level.
The Missile Interception and Fighter Interception Cabin modules have higher interception rates than the Anti-Aircraft Cannon, but they only intercept one specific type of attack (missile or ship-based). Likewise, the Powered_Pulse_Cannon is an improved version of the Anti-Aircraft Cannon and can intercept both missile and fighters, but at a slightly less effectiveness than either the Missile Interception or Fighter Interception Cabin modules.
Note that the Extreme Counterattack module isn't really a defense module nor will it contribute to your interception rate. What it does is add up to 200 points of damage to the reflected damage sent to the attacking fleet.
Note also that to take maximum advantage of any of these, Ship Defense Science should be thoroughly researched.
To figure out the total effectiveness of stacking interception modules in a single hull, see the "theory" section for the Powered Pulse Cannon for an accurate discussion.
The following table is a list of all Air Defense Modules, their blueprint location, and their requirements for initial use.
|Module Blueprint Name||Source||Honor Points||Prerequisites to use|
|Anti-Aircraft Cannon||Start with||N/A|
|Missile Interception||Instance 5||N/A|
|Fighter Interception Cabin||Instance 8||N/A|
|Powered Pulse Cannon||Instance 20||2,400||Research Missile Interception-II & Fighter Interception Cabin-II|
|Extreme Counterattack||Instance 23||3,174||Research Powered Pulse Cannon-III|
|Aldrin Particle Cannon||
|N/A||Research Extreme Counterattack-III|
The following table is a list of all Air Defense Modules, and their upgrade cost and time to upgrade. The Upgrade Time can be improved by improving the Weapon Research Center.
|Weapon Name||Cost II||Cost III||Upgrade Time II||Upgrade Time III|
|Fighter Interception Cabin||43,066||59,733||02:14:10||04:18:06|
|Powered Pulse Cannon||250,191||347,011||14:54:26||28:40:38|
|Aldrin Particle Cannon||40,000,000||80,000,000||103:43:18||237:8:27|
Enhancements and MitigatorsEdit
There are certain ships that include an Interception bonus as a part of their hull design. Otherwise, they do not. This bonus is stackable with the modules described herein.
The following Ship Defense Science research will enhance this module:
|Fast Repair Tech||+2%|
The following module will also be required to be installed in order to gain the benefit of Stability Mastery.
|Daedalus Control System||You have to install a Daedalus Control System in order to use Stability Mastery.|
|Missile Elusion||Causes a -3%, -6%, or -10% mitigation of interception rate for missiles.|
|Fighter Interception Countermeasures||Causes a -1%,-2%,-3%,-4%, or -5% mitigation of interception rate for fighters.|
