The manual for Independence War describes the function and operation of shields in this fictional universe.
The NSO 929 is also fitted as standard with two Displacement array shields fitted on wide swivel mountings. Although provided as a defensive mechanism, they may be used offensively, albeit at close range.
The principle of linear displacement has been used as a method of propulsion for over 200 years. Its potential as a defensive device is a more recent innovation. The shield array projects a steerable region of disrupted space. Radiation or material passing through that space is displaced in random directions by amounts of up to 100meters.
The shields region of disruption can be between 100m to 200m from the array itself. The region can vary in radius between 2 and 10 meters. The newest shield arrays can easily block the blast from a particle beam cannon.
An important point to remember is that the shielding zone must be kept between the ship and any hostile adversary. For this reason, the LDA is mounted on a fast linkage mechanism which can automatically track hostile vessels and keep the ship protected. The NSO-929 is fitted with two such LDAs mounted at complementary positions - each capable of covering one hemisphere.
The LDA has also been used with some success as a hostile weapon at low range, by being able to displace elements of the enemy ship's hull.
The manual for Independence War 2: Edge of Chaos gives some additional info about their tactical uses and weaknesses.
Combat ships are usually protected by one or more Linear
Displacement Array (LDA) shield systems. LDAs are an offshoot of LDS
technology that uses local spatial distortions to disrupt a small area of
space in front of the shield projector. This disperses the energy of an
incoming weapon, preventing it from damaging the hull. Or that’s what
the technical manual says. All you need to know is that if you see a
purple flash when you shoot a ship, you didn’t do it any damage.
“Shield coverage varies from ship to ship. However, the drives
are always vulnerable, so cover your ass while shooting
Another important point to remember about shields is that each LDA
decides which is the most likely enemy to fire at you and tracks that
vessel with the shield projector. You can use this to your advantage by
getting your wingmen to attack your target. The target’s LDA will not be
able to deflect the weapons from both attackers if they attack from a
