A ships' General ARea Defense Integration Anti-spacecraft Network (GARDIAN) consists of anti-missile/anti-fighter laser turrets on the exterior hull. Because these are under computer control, the gunnery control officer needs to do little beyond turn the system on and designate targets as hostile.
Since lasers move at light speed, they cannot be dodged by anything moving at non-relativistic speeds. Unless the beam is aimed poorly, it will always hit its target. In the early stages of a battle, the GARDIAN fire is 100% accurate. It is not 100% lethal, but it doesn't have to be. Damaged fighters must break off for repairs.
The speed of light in Earth's atmosphere (which we can agree is very similar to Horizon's) is about 299,702.458 km/s.
Let's observes the "projectiles" being fired on Horizon.
Travel Time≈1 second
In one second, a GARDIAN laser should travel 299,702.458 kilometers.
Horizon's radius is 5,402 kilometers.
This means it's circumference (2πr) is 33,940 kilometers.
This means that a GARDIAN laser should be able to encircle the entire planet over 8 times in the amount of time we see that "projectile" move to the, heh, "Horizon." It is clearly not comprised of photons.
Do they actually say "laser" when you're on Horizon? Because they only justification I can think of is that the acronym doesn't actually specify lasers, and thus could be applied to any defense network.
