This very common barrier creates a field of electrostatic energy around the ship that is able to absorb and redistribute energy weapons and repel projectiles. As NAM uses NDI-based systems, these barriers are usually able to absorb around 50 teratons worth of force before failing, although this can rise or fall depending on the size of the ship.
Distortion, or Hard, barriers are in place to prevent teleportation and phasing across it and into whatever it happens to be protecting. It accomplishes this duty by causing a subspace disturbance across multiple dimensions. It does not protect the ship from other things, however, and does not absorb damage. Because of this, it is often run separately from other barrier systems, so that in the event of a blow-out, the ship is still protected from teleporting and phasing threats.
Plasmatic barriers uses a scalar field to defend the ship from projectile harm. It is capable of melting incoming solid mass, and destroying electronics in missiles and other devices. It is also capable of destroying the nervous systems of enemy pilots, and detonating explosives.
Damper barriers utilize anti-gravity to create an extremely effective defense against scalar radiation.
