Railguns
This article contains information relevant to both the C# and VB6 versions of Aurora. Where differences exist, they are noted in the appropriate sections.
Railguns are a type of beam weapon.
Description
A railgun typically shoots four projectiles at once, each of which has 1/3 the damage of a similar tech Laser, for a total damage output that's 33% higher. However, due to the lower damage of each shot, it is not as good at penetrating Armor or inflicting Shock Damage, and it has a shorter range.
Maximum Range = ( Base Damage * 10000km ) * Range Modifier Rate of Fire = ( Base Damage * 3 * 5s ) / Capacitor Recharge Rate
While the theoretical maximum range far exceeds 1.5m km, no Beam Fire Control is able to handle ranges beyond this limit. Longer ranges still have some value, as they reduce the damage drop-off at longer ranges, which leads to increased damage across their effective range.
Railguns cannot be mounted in turrets.
Usage
Railguns are used in situations where their rate of fire and raw damage output are most valuable, and their weakness at armour penetration matters less. For example, they are commonly used as an early point defense weapon, as their high number of shots (as many as 4 per 5-second tick) means a lot of chances to shoot down incoming missiles or fighters. This gives them a similar role to Gauss Cannons, which are larger per shot (assuming the same accuracy), but can be mounted in turrets.
Damage Profile
The Damage Profile of a railgun uses a medium gradient, which is not as good at armour penetration as lasers, but better than Missiles or Plasma Carronades. Each shot inflicts damage separately, so the total damage inflicted by a railgun burst can be rather spread out.

Background Tech
There are three key pieces of technology involved in the creation of a Railgun.
Railgun Size or Calibre. Larger projectiles cause more damage, has higher range, but requires more power, which means it'll fire slower unless your recharge tech keeps up.
Larger laser cause more damage, has higher base range
| Calibre | 10cm | 12cm | 15cm | 20cm | 25cm | 30cm | 35cm | 40cm | 45cm | 50cm |
|---|---|---|---|---|---|---|---|---|---|---|
| Size (HS) | 3 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 13 | 15 |
| Base Damage (per Shot) | 1 | 2 | 3 | 4 | 5 | 7 | 9 | 12 | 16 | 20 |
| RP cost | 1,000 | 2,500 | 5,000 | 7,500 | 10,000 | 20,000 | 40,000 | 60,000 | 120,000 | 240,000 |
Railgun Launch Velocity The muzzle velocity of the railgun. Railguns with higher velocities can shoot their ammo further and inflict damage at greater ranges.
| Launch Velocity | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 |
|---|---|---|---|---|---|---|---|---|---|
| RP cost | 1,000 | 2,000 | 4,000 | 8,000 | 15,000 | 30,000 | 60,000 | 120,000 | 240,000 |
Capacitor Recharge Rate determines your rate of fire.
| Recharge Rate | 1 | 2 | 3 | 4 | 5 | 6 | 8 | 10 | 12 | 16 | 20 | 25 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| RP cost | 1,000 | 2,000 | 4,000 | 8,000 | 15,000 | 30,000 | 60,000 | 125,000 | 250,000 | 500,000 | 1,000,000 | 2,000,000 |
