Abh mod/Pinpoint Barrier Defense
The Pinpoint Barrier Defense was introduced in 0.4.6.
"The pinpoint barrier is a moveable shield. By default it automatically intercepts missiles. However, it can be assigned a target such as an enemy ship to turn itself toward to, hence, protecting the ship from that ship's fire.
It's an internal part and requires power. When assigned a target the shield will not react to missiles! In order to defend against missiles again the shield's target has to be canceled. However, it will not reset its current bearing. To reset its bearing quickly turn it off and on or turn the ship. It will reset its bearing when it looses target lock or the enemy ship is outside its arc.
