Air Defense Modules

Point Defense Module Overview

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.

Stacking

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.

Enhancements and Mitigators

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.

Ships that include an Interception Bonus

Ship		Bonus
Nihelbet I		5%
Nihelbet II		10%
Nihelbet III		15%
Novas Ark		20%

The following Ship Defense Science research will enhance this module:

Technology Enhancers, per module

Research		Interception Bonus
Restoration		+2%
Fast Repair Tech		+2%
Stability Mastery		+6%

The following module will also be required to be installed in order to gain the benefit of Stability Mastery.

Integrating modules

Module		Enhancement
Daedalus Control System		You have to install a Daedalus Control System in order to use Stability Mastery.

Caveats

The following Missile Science and Ship-based Science research will mitigate the benefits of the Air Defense Modules depending on the degree of research applied.

Mitigating technology, per module

Research		Mitigation
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.
